# API Reference

The two accepted OpenAPI documents are the only API facts for this section. The build publishes **61 operation pages** and fails if a source contract, generated page, SDK mapping, or downloadable specification is stale.

- [Gateway contract and seven generated methods](/api-reference/gateway)

## Choose the correct plane

| Plane       | Credential     | Purpose                                                                        |
| ----------- | -------------- | ------------------------------------------------------------------------------ |
| Admin API   | Management Key | Configure Workspaces, capacity, plans, access, keys, usage views, and billing. |
| Gateway API | Inference Key  | Send provider-compatible requests through one explicit ProviderConnection.     |

The credentials are not interchangeable. The Management SDK wraps only the Admin API; provider SDKs and agents call the Gateway directly.
