API reference

Open in ChatGPTOpen in Claude

One reference page per endpoint, generated from the API's own OpenAPI description. Each page lists the request fields, the response fields, the credits the endpoint costs, and copy-paste examples.

All endpoints live under https://YOUR_API_HOST and need an API key in the Authorization header. See authentication.

Lookups are POST requests with a JSON body.

Conventions

  • Requests and responses are JSON. Request bodies are limited to 64 KB.
  • A lookup that ran returns HTTP 200 with found true or false. Errors use the error envelope.
  • Every response has an X-Request-Id header. Quote it when you contact support.
