# API versions

The version is the first part of every address after `/api`. A version can still gain calls and fields, and have them corrected, while it is served. Each version's contract is linked below, and its pages are made from it.

| Version | Reference | Contract |
| --- | --- | --- |
| `2026-10` | [The reference](https://matrixrewards.co.uk/docs/api/2026-10.md) | `https://app.matrixrewards.co.uk/api/openapi/2026-10.json` |

A call to a version this platform does not serve is answered with [unsupported_version](https://matrixrewards.co.uk/docs/errors/unsupported_version.md), which lists the versions that are.
