# OpenAPI specs

> Download the Partner API's OpenAPI description, per version.

The full OpenAPI description is served live and unauthenticated, so you can generate a client or import it into Postman without a key. It comes in two forms.

## The version-resolving URL

```
GET https://api.clemta.com/v1/openapi.json
```

Served without a key, so it has no account default to fall back on: pass `?version=YYYY-MM-DD` (or the `Clemta-Version` header) to pin a version, otherwise it serves the latest. Use this when you always want the description that matches the contract you call.

## Frozen, dated URLs

Each dated version is also served at its own stable path. These never change once published, so they are safe to vendor into a build.
