# Download the canonical Router HTTP contract

`GET /openapi.json`

Returns this exact OpenAPI 3.1 document without authentication. Agents and code generators can use it to discover every HTTP operation, request shape, response shape, error code, and lifecycle convention. Streaming speech operations are described by the AsyncAPI document in the public Gateway repository.

## Response `200`

The canonical OpenAPI 3.1 document.

- object — An OpenAPI 3.1 document.

## Other responses

- `429` — The request exceeded an edge request quota, an organization concurrency limit, or a provider rate limit. The body identifies the stable failure class; Retry-After gives the minimum safe delay.
- `default` — Normalized failure. Every non-2xx response carries this envelope; the Router never forwards a raw provider response body.

## Changes
