How it works

POST a conversation. Get back a structured assessment: harmfulness score, predatory-user identification, risk tier, confidence, and latency. That's it.

Authentication

Every request carries a bearer token. Create and revoke API keys from your account dashboard once you're approved.

$ curl https://api.polycreek.org/v2/predict \
-H "Authorization: Bearer sk-aletheia-..." \
-H "Content-Type: application/json"
POST /v2/predict

Single Prediction

Score one conversation in real time. Use this for live moderation on chat, DM, and messaging platforms.

  • Sub-50ms p95 latency
  • Multi-task output: harmfulness, predator ID, risk tier
  • Per-request pricing on standard tier
