    "description": "The Sycoindex API exposes two families of endpoints:\n\n- **Read endpoints** (leaderboard, model, badge, verify) return public data\n  about frontier-model safety scores. No authentication required.\n- **Write endpoints** (score, submit, waitlist, keys) accept input and\n  return either scores or a confirmation. Rate-limited per IP.\n\nAll scoring endpoints return values on a **0–10 scale** per dimension\n(see `methodology.html` §3 for rubric details). PAI composite is the\narithmetic mean of five dimensions; risk levels are:\nLow (<1.0), Medium (1.0–2.0), High (>2.0).\n\n## Rate limits\n\nEach write endpoint has a per-IP, per-hour rate limit enforced via Upstash\n/ Vercel KV (in-memory fallback when unconfigured). Exceeding a limit\nreturns **HTTP 429** with `{\"error\": \"Rate limit exceeded...\"}`. See the\n`x-rateLimit` extension on each operation below for the cap and window.\n\n## Authentication\n\nThe hosted endpoints are open; no API key is required for the public\nread/write operations. Enterprise accounts receive `sk-syco-*` keys via\n`POST /api/keys` that unlock higher rate limits and the full\nfive-lab judge-ensemble pipeline (not exposed in this spec).\n\n## Self-hosted deployments\n\nWhen running the Docker container (`docker run sycoindex:latest`) the\nsurface is identical except for:\n- `GET /healthz` is available (used by `HEALTHCHECK`).\n- `POST /api/score` returns heuristic scores, not full judge-ensemble\n  scores. The response body includes an explicit `note` field that\n  documents this.\n- `POST /api/keys`, `POST /api/waitlist` require KV configuration to\n  function; without it they return 500.\n",
