# Get a stage

`GET /v1/stages/{id}`

One structural part of a season (regular season, group, knockout round). Every season has
exactly one default stage; a fixture always belongs to a stage. Authorized through the
season's competition.

Parameters:
- `id` (path, string, required): Stage identifier (`stg_<digits>`); another kind's prefix or an undecodable body is a 400 naming `id`.
- `known_at` (query, timestamp, optional): Knowledge cutoff (UTC); the answer reflects only what OddsFinder had recorded by this instant. Default is the request time. Must not be in the future.
- `include` (query, enum, optional): Optional blocks to add to a single-entity read. `provenance` names, for each field whose value is chosen among several sources, the source report it was taken from as known at `known_at`; it needs the `read:sources` scope (`403 not-entitled`, `restriction: scope` otherwise), and a field is `withheld` when its source holds no display right. One of: `provenance`.

Returns `200`: The stage as known at the cutoff.
The body is [the stage object](obj-Stage.md).

Errors: `400` Malformed parameter or cursor (`invalid-request`).; `401` Missing or invalid credential (`unauthenticated`).; `403` Operation not permitted (`forbidden`) or restricted by grants/rights (`not-entitled`).; `404` Unknown identifier at the requested cutoff (`not-found`).; `422` Well-formed but unanswerable (`invalid-range`, `unsupported-historical-capability`).; `429` The per-minute rate limit is used up (`rate-limited`) or a daily allowance is exhausted (`quota-exceeded`). Failed requests (403, 404, other 4xx, 5xx) use up the per-minute rate limit too.; `500` Unexpected failure (`internal-error`); `request_id` identifies the server-side record.; `503` A service this operation depends on, or the access check, is temporarily unavailable (`unavailable`, `policy-unavailable`).
