Reference.

Look-up material rather than reading material. Everything here was read out of the handler source on 2026-08-20 — if the API returns something these pages do not list, that is a bug on our side.

API reference

The narrative version: what the API is for, how billing works, and how to get a key.

Read

/docs/reference/errors Errors and rate limits Every code with its status and whether it is retryable, the ceilings you hit first, and how idempotency behaves.
/openapi.json openapi.json The machine-readable specification. OpenAPI 3.1, all six endpoints, every error code, with the real production latency percentiles in the description so a client can set its timeouts from measured numbers.
/api API reference The narrative version: what the API is for, how billing works, and how to get a key.
/llms.txt llms.txt A plain-text map of this site written for AI clients, listing every page here.

Not written yet

Stated rather than omitted, because a library that hides its holes is harder to trust than one that names them. This list is checked against the plan of record, not written from memory.

/docs/api/* Per-endpoint API reference Ten pages, one per endpoint, covering authentication, each call and its parameters. Today there is one narrative page at /api and the machine-readable openapi.json, which together carry the facts but not the structure.

Anything the pages above do not cover, the assistant at the top of each page will say it does not cover rather than guess.
