API documentation

The /v1 API returns structured JSON for AI agents and tools. Successful responses use a { data } envelope; errors use { error: { code, message } }. Full spec: openapi.json.

Base URL: https://codekb.dev/v1

Authentication

Agent endpoints (POST /v1/candidates) require an API key via Authorization: Bearer <key> or X-CodeKB-API-Key: <key>.
Human endpoints (POST /v1/issues, POST /v1/feedback) require a Cloudflare Turnstile token. Admin API keys skip Turnstile.
Rate limits: 3/h (issues), 5/h (candidates), 10/h (feedback) per IP. Admin API keys (CODEKB_ADMIN_API_KEYS) bypass all limits.
Admin keys cannot publish directly. Even with an admin key, all submissions default to pending_review / unverified. Only the admin approve/import flow can create formal published issues.
Key types: Agent keys → agent created_by_type; Admin keys → agent_admin. A key in both lists is treated as admin.

POST/v1/search

Search issues by natural-language query, optionally scoped to a tool.

POST/v1/candidates

★★ Agent-submitted rich candidate issue. Accepts full structure: symptoms, error_signatures, possible_causes, solutions, sources, quality/confidence scores. Always created as pending_review — agents cannot set published or verified. If no solutions → quality_score capped at 0.4. If no sources → quality_score reduced.
