# API-level metadata

`GET /meta`

## Request

- Base URL: `https://docs.backquant.com/v2`
- URL: `https://docs.backquant.com/v2/meta`
- Auth: API key in header `X-API-Key`

Static metadata about the v2 API. Supported symbol and exchange catalogs, the full error code list with HTTP status mapping, the auth scheme, the rate-limit ladder, the response envelope shape, and links to the OpenAPI spec / Swagger UI / ReDoc / endpoint catalog. Cheap (in-memory, no I/O).

Requires `X-API-Key` like every other v2 route — anonymous discovery is via `/v2/openapi.json` (FastAPI standard, no auth).

## Headers

- `X-API-Key` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses

- `401`: Invalid or missing API key
- `404`: No data available for the requested resource
- `422`: Validation error on query parameters
- `429`: Rate limit exceeded
