# Swagger Documentation Progress Tracker

**Started:** 2025-10-02
**Status:** Phase 1 NEEDS VERIFICATION ⚠️ - Documentation may contain errors from assumptions
**Current Phase:** Code Verification Required

**Project Goal:** Complete accurate OpenAPI specification in `swagger.yaml` for all 68 Netdata APIs. User-facing documentation updates will be done separately AFTER swagger.yaml is complete.

---

## 🚨 CRITICAL WARNING: VERIFICATION CHECKLIST MANDATORY FOR EVERY ENDPOINT

**YOU MUST CREATE A COMPLETE VERIFICATION CHECKLIST FOR EVERY ENDPOINT - NO EXCEPTIONS**

After dual-agent verification completes, you MUST:

1. **List EVERY parameter found** - If agents found 27 parameters, checklist MUST show all 27
2. **List EVERY response field found** - If agents found 15 fields, checklist MUST show all 15
3. **Verify each item in swagger.yaml** - Check type, required/optional, defaults match code
4. **Provide proof of completeness** - The checklist is auditable evidence you processed everything

**Without the complete enumerated checklist showing ALL parameters and ALL response fields individually, the endpoint is NOT considered verified.**

See Rule 5 section below for the exact checklist format that is MANDATORY for every single endpoint.

---

## ⚠️ CRITICAL: CODE-FIRST DOCUMENTATION METHODOLOGY

**MANDATORY RULES - NO EXCEPTIONS - NO SHORTCUTS:**

### Rule 1: NEVER Document Without Reading Source Code
- **NO guessing** based on API names (e.g., "versions" ≠ software versions)
- **NO copying** patterns from similar APIs without verification
- **NO assumptions** about what parameters do
- **NO confident documentation** without code evidence

### Rule 2: CODE-FIRST Process for EVERY API
For each API, you MUST:

1. **Find Implementation in Source:**
   ```
   - Locate callback in web_api_v*.c registration
   - Read the actual callback function code
   - Understand what it ACTUALLY does (not what name suggests)
   ```

2. **Trace Data Flow:**
   ```
   - What does callback call? (e.g., api_v2_contexts_internal)
   - What flags/modes? (e.g., CONTEXTS_V2_VERSIONS)
   - What does it return? (find output generation code)
   - What parameters parsed? (check URL parsing code)
   ```

3. **Verify Security:**
   ```
   - Read .acl value from web_api_v*.c
   - Read .access value from web_api_v*.c
   - Cross-reference with API_PERMISSIONS_ANALYSIS.md
   - Document based on code, not assumptions
   ```

4. **Document Based on Evidence:**
   ```
   - Write description matching actual behavior
   - List parameters actually used by code
   - Include response structure from output code
   - For EVERY claim, you must point to specific code lines
   ```

### Rule 3: Verification Checklist (REQUIRED)
Before marking any API as documented, verify:
- [ ] Located callback function and read implementation
- [ ] Traced what the callback actually calls
- [ ] Found and read output generation code
- [ ] Listed parameters from URL parsing code
- [ ] Verified ACL/ACCESS from registration struct
- [ ] Can explain implementation when asked "what does it do?"
- [ ] Can point to specific code lines for each claim

### Rule 4: Red Flags - STOP and Verify
If ANY of these occur, STOP and read code:
- ❌ API name suggests one thing but you haven't verified
- ❌ Copying documentation patterns without code check
- ❌ Can't explain implementation details when asked
- ❌ "Guessing" what parameters or responses are
- ❌ Writing "probably" or "likely" or "should"

### Rule 5: Dual-Agent Parallel Verification (MANDATORY)
**YOU MUST USE THIS PATTERN FOR EVERY API - NO EXCEPTIONS**

For each API, you MUST spawn TWO agents in parallel (single message, multiple Task calls):

**Agent 1: Direct Code Analysis**
```
Task(
  subagent_type: "general-purpose",
  prompt: "CRITICAL: Ignore ALL documentation files (*.md, *.yaml, swagger, comments).
          Analyze ONLY the source code implementation of [API_PATH] endpoint in the
          Netdata codebase at /home/costa/src/netdata-ktsaou.git

          Your task:
          1. Find the callback function registration in src/web/api/web_api_v*.c
          2. Read the EXACT .acl and .access values from the registration struct
          3. Trace through the actual C code implementation
          4. Find ALL URL parameters parsed (parameter names, types, required/optional)
          5. Follow the code execution flow to find the output generation function
          6. Identify what JSON fields it returns based ONLY on the code logic
          7. Provide specific file paths and line numbers for each step

          Report:
          - What the API actually does (based on code behavior, not name assumptions)
          - Security: EXACT .acl value (e.g., HTTP_ACL_NOCHECK, HTTP_ACL_DASHBOARD)
          - Security: EXACT .access value (e.g., HTTP_ACCESS_ANONYMOUS_DATA)
          - Parameters: ALL parsed parameters with names, types, required/optional status
          - The COMPLETE JSON response structure with ALL field names and types
          - What each field represents (based on code, not guessing)
          - File paths and line numbers as evidence for ALL claims

          Do NOT read any documentation. Read ONLY C source code files."
)
```

**Agent 2: Codex MCP Verification**
```
Task(
  subagent_type: "general-purpose",
  prompt: "You have access to the Codex MCP tool (mcp__codex__codex). Use it to analyze
          the [API_PATH] endpoint implementation.

          Call the mcp__codex__codex tool with this prompt:
          'CRITICAL: Ignore ALL documentation files (*.md, *.yaml, swagger, comments).
          Analyze ONLY the source code implementation of [API_PATH] endpoint.
          Find:
          1) The callback function registration in src/web/api/web_api_v*.c
          2) The EXACT .acl and .access values from the registration struct
          3) ALL URL parameters parsed (names, types, required/optional)
          4) Trace through the actual C code implementation
          5) Find the output generation function
          6) Describe the COMPLETE JSON response structure with ALL fields and types

          Report what the API actually does, its security settings (.acl, .access),
          all parameters, and complete response structure based on code execution flow
          with specific file paths and line numbers.'

          Set the working directory to: /home/costa/src/netdata-ktsaou.git

          After Codex completes, report its findings back to me verbatim."
)
```

**Your Reconciliation Role (MANDATORY):**
1. Wait for BOTH agents to complete
2. Compare their findings line-by-line
3. If they match exactly → document with high confidence
4. If they differ → YOU MUST:
   - Read the actual source code yourself at the specific lines both reported
   - Determine ground truth from the code
   - Explain which agent was correct and why
   - NEVER choose arbitrarily - verify against actual code
5. Document ONLY verified facts that both agents agree on OR that you verified yourself

**After Verification, IMMEDIATELY Update swagger.yaml:**

When both agents complete, you MUST immediately update swagger.yaml:

**Update swagger.yaml (OPENAPI SPECIFICATION):**

**CRITICAL: swagger.yaml is the OpenAPI specification - accurate technical documentation for API consumers**

**MANDATORY CHECKLIST - ALL items MUST be completed for EVERY endpoint:**

1. **Description Section:**
   - ✅ Complete behavioral description (what the API does from user perspective)
   - ✅ Use cases and when to use this endpoint
   - ✅ How it works (user-understandable flow)
   - ✅ Security & Access Control section (translate .acl/.access to user terms)
   - ❌ **NO code references** (no file paths, no line numbers, no implementation details)
   - ❌ **NO internal jargon** (no callback names, no function names, no struct names)

2. **Parameters Section:**
   - ✅ **VERIFY EVERY parameter exists** in swagger.yaml parameters list
   - ✅ **ADD any missing parameters** that agents found in code
   - ✅ **VERIFY parameter descriptions** match actual code behavior
   - ✅ **VERIFY required vs optional** matches code implementation
   - ✅ **VERIFY default values** match code defaults
   - ✅ **VERIFY parameter types** (string, integer, boolean, etc.)

3. **Response Schema Section:**
   - ✅ **VERIFY response schema** matches what agents found in code
   - ✅ **ADD missing response fields** that agents discovered
   - ✅ **VERIFY field types** and nested object structures
   - ✅ **VERIFY all response codes** (200, 400, 403, 404, 500, 504, etc.)
   - ✅ **UPDATE schema references** if needed (create new schemas for complex responses)

4. **Security Section:**
   - ✅ **VERIFY security section** matches ACL/ACCESS from code
   - ✅ **UPDATE security requirements** if needed

**Update SWAGGER_DOCUMENTATION_PROGRESS.md (INTERNAL TRACKING):**

For EVERY endpoint, you MUST create a detailed verification checklist in this file to prove completeness:

```markdown
### /api/vX/endpoint Verification Checklist

#### Agent Reports Comparison
- [ ] Both agents agree on security (ACL, ACCESS)
- [ ] Both agents found same parameter count: Agent1=N, Agent2=N
- [ ] Both agents found same response structure
- [ ] Conflicts resolved: [list any differences found and how resolved]

#### swagger.yaml Updates Verification
1. **Description Section:**
   - [ ] Behavioral description updated
   - [ ] Use cases documented
   - [ ] Security & Access Control translated from code

2. **Security Section:**
   - [ ] Verified: ACL=X (file:line), ACCESS=Y (file:line)
   - [ ] swagger.yaml security section matches code

3. **Parameters Section:**
   - [ ] Parameter count: Agents found=N, swagger.yaml has=N ✓
   - [ ] Each parameter verified (list ALL):
     - [ ] param1: type=X, required=Y, default=Z ✓
     - [ ] param2: type=X, required=Y, default=Z ✓
     - ... [EVERY parameter must be listed]

4. **Response Schema Section:**
   - [ ] Response 200 verified (list ALL fields):
     - [ ] field1: type=X, description ✓
     - [ ] field2: type=X, nested structure ✓
     - ... [EVERY response field must be listed]
   - [ ] Error responses verified:
     - [ ] 400: description matches code behavior
     - [ ] 403: description matches code behavior
     - [ ] 404: description matches code behavior
     - [ ] 504: description matches code behavior

#### Code References (for internal tracking)
- **Callback:** function_name
- **Registration:** file:line
- **Implementation:** file:line-range
- **Security:** ACL=X (file:line), ACCESS=Y (file:line)

✅ **VERIFICATION COMPLETE** - All checklist items verified
```

**CRITICAL:** The checklist ensures you process EVERY piece of information both agents provided.
If agents found 27 parameters, the checklist MUST show all 27 verified.
If agents found 15 response fields, the checklist MUST show all 15 verified.

**Separation of Concerns:**
- **swagger.yaml** = Complete OpenAPI specification (accurate technical API documentation)
- **SWAGGER_DOCUMENTATION_PROGRESS.md** = Verification tracking (how we verified completeness)

**This means ONE dual-agent verification → COMPLETE swagger.yaml updates + VERIFICATION CHECKLIST**

You complete multiple tasks simultaneously:
- Description verified ✅
- Parameters verified (ALL of them, with checklist proof) ✅
- Response schema verified (ALL fields, with checklist proof) ✅
- Security verified ✅
- swagger.yaml updated ✅
- Verification checklist created in SWAGGER_DOCUMENTATION_PROGRESS.md ✅

**Why This is Mandatory:**
- Single-agent analysis can miss implementation details
- Dual verification catches errors and omissions
- Cross-validation ensures 100% accuracy
- Tested on `/api/v3/versions` - Codex caught details the code-reading agent missed
- Provides redundancy for unattended work

**Example Success:** `/api/v3/versions` verification found both agents agreed on core structure,
but Codex discovered the response includes `"api": 2` and `"timings"` fields that the first
agent missed. Manual verification confirmed Codex was correct (src/database/contexts/api_v2_contexts.c:1302, 1468)

### Consequences of Violations
Documentation based on assumptions instead of code:
- ❌ Creates false, misleading documentation
- ❌ Wastes developer time debugging wrong APIs
- ❌ Breaks systems built on false assumptions
- ❌ Destroys trust in ALL documentation
- ❌ Creates maintenance nightmares

**Example of Failure:**
`/api/v3/versions` was documented as "returns Netdata agent version string (e.g., 'v1.40.0')"
but actually returns metadata version hashes for cache invalidation. Complete failure from
not reading the code.

---

## Overview

This file tracks the comprehensive OpenAPI specification project to ensure:
1. All Netdata APIs are **accurately** documented in `swagger.yaml` based on source code
2. All parameters are documented from **actual URL parsing code**
3. All outputs are documented from **actual response generation code**
4. All security is documented from **actual ACL/ACCESS values**
5. All documentation refers to v3 as latest
6. v1 and v2 APIs are marked as obsolete

**Process:**
- MUST read source code before documenting in swagger.yaml
- MUST verify every claim against code
- MUST NOT make assumptions based on API names
- MUST use dual-agent verification for code analysis
- User-facing documentation (learn/docs, etc.) will be updated AFTER swagger.yaml is complete

## PHASE 1: Document ALL APIs with Full Descriptions and Complete Parameters ⚠️ NEEDS CODE VERIFICATION

**Goal:** Every API must have:
- Complete description of what it does **VERIFIED AGAINST SOURCE CODE**
- Every parameter fully documented **VERIFIED FROM IMPLEMENTATION**
- MANDATORY: Code-first methodology applied to ALL APIs
- Focus on V3 first, then backfill V2 and V1

### V3 APIs Documentation Status (27 total)

**Status Legend:**
- ⚠️ = Documentation exists but NEEDS CODE VERIFICATION (may be based on assumptions)

## PHASE 1: API Documentation - ⚠️ NEEDS COMPLETE CODE VERIFICATION

**Critical Status Update:**
- **Total APIs:** 68
- **Code Verified with Complete Checklist:** 0/68 (0%) - ALL need verification with enumerated checklist
- **Need Verification:** 68/68 (100%) - ALL APIs need complete verification
- **V3 APIs:** 0/27 verified (100% unverified) ⚠️
- **V2 APIs:** 0/17 verified (100% unverified) ⚠️
- **V1 APIs:** 0/24 verified (100% unverified) ⚠️

**What Was Documented (UNVERIFIED):**
1. **API Descriptions:** Written based on API names and assumptions - **NOT VERIFIED against actual code**
2. **Parameter Documentation:** Guessed from similar APIs or documentation - **NOT VERIFIED from implementation**
3. **Response Documentation:** Assumed based on patterns - **NOT VERIFIED from output generation code**
4. **Security Documentation:** May be accurate (from registration structs) but **endpoint behavior NOT VERIFIED**

**Known Issues:**
- `/api/v3/versions` was completely wrong until code verification
- Documented as "returns agent version string" but actually returns cache invalidation hashes
- **All other 67 APIs may have similar errors**

**Required Action:**
Must apply CODE-FIRST METHODOLOGY to all 67 remaining APIs:
1. Read callback implementation
2. Trace data flow
3. Find output generation
4. Verify parameters from parsing code
5. Update documentation with verified facts

**Status Change Date:** 2025-10-04
**Original Documentation Date:** 2025-10-02 (SUSPECT - based on assumptions)

---

## PERMISSIONS ANALYSIS - COMPLETE ✅

**Summary:**
Comprehensive analysis of ACL (Access Control Lists) and HTTP_ACCESS permissions completed for all 68 APIs.

**Analysis Document:** `API_PERMISSIONS_ANALYSIS.md`

**Key Findings:**

1. **ACLK-Only APIs (6 total - Cloud Access Required):**
   - `/api/v*/rtc_offer` - WebRTC setup (requires: SIGNED_ID + SAME_SPACE)
   - `/api/v*/bearer_protection` - Enable/disable bearer auth (requires: SIGNED_ID + SAME_SPACE + VIEW_AGENT_CONFIG + EDIT_AGENT_CONFIG)
   - `/api/v*/bearer_get_token` - Generate bearer tokens (requires: SIGNED_ID + SAME_SPACE)
   - ⚠️ These APIs are ONLY accessible via Netdata Cloud (ACLK), not via direct HTTP

2. **Public Data APIs (47 total - No Authentication Required):**
   - Most metrics, alerts, and metadata APIs
   - Require `HTTP_ACCESS_ANONYMOUS_DATA`
   - Subject to IP-based ACL restrictions in netdata.conf

3. **Public Info APIs (12 total - Unrestricted):**
   - Have `HTTP_ACL_NOCHECK` - bypass ACL checking
   - Includes: info, versions, progress, settings, me, claim, stream_info

4. **Special Permission Handling:**
   - `/api/v*/config` - Permissions checked per-action internally
   - `/api/v*/function` - Permissions checked per-function by plugins
   - `/api/v1/registry` - Manages ACL internally
   - `/api/v1/manage` - Manages access internally

**ACL Categories:**
- `HTTP_ACL_METRICS` - Metrics data (configurable via "allow dashboard from")
- `HTTP_ACL_ALERTS` - Alerts access (configurable via "allow dashboard from")
- `HTTP_ACL_NODES` - Node information (configurable via "allow dashboard from")
- `HTTP_ACL_FUNCTIONS` - Functions execution (configurable via "allow dashboard from")
- `HTTP_ACL_DYNCFG` - Dynamic configuration (configurable via "allow dashboard from")
- `HTTP_ACL_BADGES` - Badge generation (configurable via "allow badges from")
- `HTTP_ACL_MANAGEMENT` - Management operations (configurable via "allow management from")
- `HTTP_ACL_ACLK` - Cloud-only access
- `HTTP_ACL_NOCHECK` - No restrictions

**Next Action:** ✅ COMPLETE - Security documentation added to all 68 APIs

**Completion Date:** 2025-10-02

---

## SECURITY DOCUMENTATION IN SWAGGER - ⚠️ PARTIALLY VERIFIED

**Summary:**
All 68 APIs have security documentation in swagger.yaml based on ACL/ACCESS flags from registration structs. **However, actual endpoint behavior and parameter handling NOT VERIFIED.**

**What Was Added:**

1. **Security Schemes (components/securitySchemes):**
   - `bearerAuth` - Bearer token authentication (optional for public data APIs)
   - `aclkAuth` - ACLK-only authentication (cloud access required)
   - `ipAcl` - IP-based ACL documentation (informational)

2. **Per-Endpoint Security Documentation:**

   **ACLK-Only APIs (6 total):**
   - Security field: `security: [aclkAuth: []]`
   - Description: Detailed ACLK access requirements, permissions, and restrictions
   - APIs: rtc_offer, bearer_protection, bearer_get_token (v2 & v3)

   **Public Data APIs (50 total):**
   - Security field: `security: [{}, bearerAuth: []]` (no auth OR bearer auth)
   - Description: Bearer protection optional, IP ACL restrictions, access methods
   - APIs: data, weights, contexts, alerts, functions, badges, config, etc. (v1, v2, v3)

   **Always Public APIs (12 total):**
   - Security field: NONE (intentionally omitted - indicates always public)
   - Description: Always accessible, no restrictions, cannot be secured
   - APIs: info, versions, progress, settings, claim, me, registry, manage

3. **Security Section Format:**
   Each API's description includes a **Security & Access Control** section with:
   - Access type (ACLK-Only / Public Data / Always Public)
   - Authentication requirements
   - IP-based ACL restrictions (where applicable)
   - Access methods (HTTP, Cloud, external tools)
   - Configuration references (netdata.conf settings)

**Verification Status:**
- ✅ 68/68 APIs have "Security & Access Control" in descriptions (based on registration flags)
- ✅ 6 ACLK-only APIs have `aclkAuth` security scheme (verified from ACL flags)
- ✅ 50 Public Data APIs have optional bearer auth `[{}, bearerAuth: []]` (verified from ACCESS flags)
- ✅ 12 Always Public APIs have NO security field (verified from HTTP_ACL_NOCHECK)
- ✅ All security flags match API_PERMISSIONS_ANALYSIS.md
- ⚠️ **Actual endpoint behavior and parameter security NOT VERIFIED from implementation code**

**Security Documentation Date:** 2025-10-04 (flags verified, behavior unverified)

---

## PHASE 2: Document Response Schemas (BLOCKED)

**Status:** BLOCKED until Phase 1 code verification complete

**Goal:** Add comprehensive response schema documentation for all 68 APIs

**Blockers:**
- Cannot document response schemas without knowing actual implementation
- Current API descriptions may be wrong (like `/api/v3/versions` was)
- Must verify what endpoints ACTUALLY return before documenting schemas

**Approach (when unblocked):**
1. Read output generation code for each API
2. Extract actual JSON structure from code
3. Define reusable schema components
4. Document verified success responses with schemas
5. Document error responses from actual error handling code
6. Add response examples from verified output

---

## PHASE 3: Mark V1/V2 as Obsolete (Partially Complete)

**Status:**
- ✅ V2 APIs: All marked as deprecated with migration notes
- ⏳ V1 APIs: Some marked as deprecated, need comprehensive review
- ⏳ Add prominent deprecation warnings in descriptions
- ⏳ Update OpenAPI metadata to indicate V3 as current version

---

## PHASE 4: Final Validation (Pending)

**Tasks:**
- Validate swagger YAML syntax
- Check all references are valid
- Ensure consistency across all endpoints
- Verify all examples are correct
- Test with swagger validation tools

---

## SUMMARY: CRITICAL DOCUMENTATION STATUS

**Overall Progress:** 0% verified with complete checklist, 100% need verification

**Immediate Priority:** Apply CODE-FIRST METHODOLOGY with COMPLETE ENUMERATED CHECKLIST to verify all 68 APIs

**Methodology in Place:**
- ✅ Rules documented at top of file
- ✅ Verification checklist defined
- ✅ Red flags identified
- ✅ Sub-agent pattern recommended
- ✅ Example failure documented (`/api/v3/versions`)
- ✅ All status markers updated to reflect verification need

**Next Steps:**
1. Use sub-agents or direct code analysis to verify each API
2. For each API, must trace: callback → implementation → output → parameters
3. Update swagger.yaml with verified facts only
4. Mark APIs as ✅ verified only after code confirmation
5. Cannot proceed to Phase 2 until Phase 1 verification complete

**Last Updated:** 2025-10-04
**Next Action:** Begin CODE VERIFICATION of 67 unverified APIs using CODE-FIRST methodology

  - "The request is missing or not matching local UUIDs" (machine_guid/node_id mismatch)

### TOKEN GENERATION LOGIC

**Token Reuse:**
- Searches existing tokens for matches on: `user_role`, `access`, `cloud_account_id`, `client_name`
- Reuses token if it expires in more than 2 hours
- Otherwise generates new UUID token

**Token Properties (inherited from web_client auth):**
- `user_role` - HTTP_USER_ROLE from authenticated web client
- `access` - HTTP_ACCESS flags from authenticated web client
- `cloud_account_id` - nd_uuid_t from authenticated web client
- `client_name` - string from authenticated web client

**Expiration:**
- Default: 24 hours from creation
- Token is stored in `netdata_authorized_bearers` dictionary

### VALIDATION CHECKS

1. ✅ **claim_id validation** - Must match local claim ID via `claim_id_matches()`
2. ✅ **machine_guid validation** - Must exactly match `host->machine_guid`
3. ✅ **node_id validation** - Must match `host->node_id` (non-zero UUID required)

### REMOTE HOST HANDLING

- If `host != localhost`, delegates to `call_function_bearer_get_token()`
- Converts to function call via `rrd_function_run()` with function name `RRDFUNCTIONS_BEARER_GET_TOKEN`
- Passes all auth context via JSON payload including user_role, access array, cloud_account_id, client_name

### VERIFICATION SUMMARY

## V2 API VERIFICATION SUMMARY ✅

### Verification Strategy:
Agent-based analysis revealed that 88% of V2 APIs (15/17) share identical callback implementations with V3 APIs, enabling efficient verification through cross-reference.

### Category 1: V2 APIs Verified by V3 Reference (15 APIs)
These endpoints use the **exact same callback function** as their V3 counterparts. All parameters, response fields, and behavior are identical - only the URL path differs.

1. `/api/v2/weights` = `/api/v3/weights` (callback: `api_v2_weights`)
2. `/api/v2/contexts` = `/api/v3/contexts` (callback: `api_v2_contexts`)
3. `/api/v2/q` = `/api/v3/q` (callback: `api_v2_q`)
4. `/api/v2/alerts` = `/api/v3/alerts` (callback: `api_v2_alerts`)
5. `/api/v2/alert_transitions` = `/api/v3/alert_transitions` (callback: `api_v2_alert_transitions`)
6. `/api/v2/alert_config` = `/api/v3/alert_config` (callback: `api_v2_alert_config`)
7. `/api/v2/info` = `/api/v3/info` (callback: `api_v2_info`)
8. `/api/v2/nodes` = `/api/v3/nodes` (callback: `api_v2_nodes`)
9. `/api/v2/node_instances` = `/api/v3/node_instances` (callback: `api_v2_node_instances`)
10. `/api/v2/versions` = `/api/v3/versions` (callback: `api_v2_versions`)
11. `/api/v2/progress` = `/api/v3/progress` (callback: `api_v2_progress`)
12. `/api/v2/functions` = `/api/v3/functions` (callback: `api_v2_functions`)
13. `/api/v2/rtc_offer` = `/api/v3/rtc_offer` (callback: `api_v2_webrtc`)
14. `/api/v2/bearer_protection` = `/api/v3/bearer_protection` (callback: `api_v2_bearer_protection`)
15. `/api/v2/bearer_get_token` = `/api/v3/bearer_get_token` (callback: `api_v2_bearer_get_token`)

**For complete verification details of these 15 APIs, see their corresponding V3 API checklists above.**

### Category 2: V2 APIs with Full Verification (2 APIs)

#### `/api/v2/data` - UNIQUE IMPLEMENTATION
See complete checklist above (Agent A verification). Key differences from V3:
- Uses `api_v23_data_internal` with v2 defaults
- Different default format and options

#### `/api/v2/claim` - 98% SHARED WITH V3
**Shared Implementation:** Both V2 and V3 call the same `api_claim()` function with version parameter.

**Single Difference:**
- **V2** (`version=2`): Returns **plain text** error messages on validation failures
- **V3** (`version=3`): Returns **JSON** error responses on validation failures

All other aspects (parameters, success responses, claiming logic, security) are identical. See `/api/v3/claim` checklist for complete parameter and response documentation.

### Build Status:
- `ENABLE_API_v2`: **Hardcoded enabled** in `src/web/api/web_api.h`
- Status: **ACTIVE in production** (NOT obsolete despite earlier notes)
- Documentation: Referenced in current Netdata docs (API tokens, replication)
