The [any-system guide](/integrations/overview) explains how to prepare each route; the [A2A guide](/agents/a2a) documents the current public agent separately. The preview clients do not install a connector, schedule a sync, or activate a supplier. An agent skill does not give its user account or commercial authority.

## Check before calling

The live application contract is at `https://middlemantechnologies.com/openapi.json`. The [supplier preview OpenAPI file](https://middleman.mintlify.app/downloads/supplier-openapi.json) describes the implementation being prepared for release.

If the live contract lacks a supplier route, wait for the application release. Do not treat a `404`, login page or framework response as a successful integration. When available, `/api/v1/supplier/me` reports the capabilities your key can use. This preview reports `validate: true`, with `ingest`, `publish`, `quote`, `reserve` and `order` all `false`.

The existing [public read API](/developers/overview) is separate and does not require a supplier key.
