/v1/* request requires your server-side API key:
GET /healthz and GET /readyz do not require authentication.
Every response includes x-request-id. Record it for troubleshooting. Do not log API keys, query text, document text, or complete request bodies.
Timestamps use ISO 8601 UTC. Usage token totals are decimal strings. Scores order results within a response and do not have a fixed global range.
The API is versioned under /v1. Clients should ignore unknown response fields. Partner-impacting changes will be recorded in the changelog.
