# API reference index

Use these references for the supported workflows described in this manual. An application network request is not automatically a public integration contract.

| Interface            | Reference                                       | Authentication context                                |
| -------------------- | ----------------------------------------------- | ----------------------------------------------------- |
| Project GraphQL      | [Generated schema](/docs/api/graphql/reference) | Project-authorized token or supported signed-in flow. |
| Assets               | [Upload and metadata](/docs/api/assets)         | Authorized project request.                           |
| File delivery        | [Files](/docs/api/files)                        | Original bytes, inline viewing, and downloads.        |
| Image delivery       | [Images](/docs/api/images)                      | Delivery URL; separate from Studio membership.        |
| Studio search        | [Search hook](/docs/api/search)                 | Signed-in Studio context.                             |
| Outgoing events      | [Webhooks](/docs/api/webhooks)                  | Receiver authentication configured in headers.        |
| AI client connection | [MCP](/docs/integrations/mcp)                   | OAuth user authority.                                 |
| Application tools    | [Tool contract](/docs/reference/tools)          | Signed server invocation.                             |

Manage chats, runs, approvals, skills, memberships, and integrations through the documented product workflows unless a separately supported API contract is provided for your integration. Do not build a production dependency on undocumented Dashboard session endpoints.

For client failures, distinguish transport status from GraphQL errors and business outcome. Include redacted request IDs and timestamps when seeking [support](/docs/support).
