Find a custom connection's models through the sign-in box (writes nothing)

POST

/connections/ai-accounts/custom/discover

• Production

May require, depending on the request: connections.write, connections.org.write

Authorizations

• bearerAuth

Parameters

Header Parameters

x-uai-org

string

Org scope: me or an org slug. Absent means the caller’s active/personal org. It selects the workspace used for permission checks and for most resource filters; operation-specific access rules still apply.

Request Body ^required

object

scope

required

org: the workspace’s accounts, used by every member’s tasks; me: the caller’s own, in this workspace.

string

Allowed values: org me

providerType

required

openrouter: an OpenRouter key; bedrock: an Amazon Bedrock API key; custom: any endpoint that speaks the engine’s protocol.

string

Allowed values: openrouter bedrock custom

engine

required

Claude Code or Codex. One connection serves one engine.

string

Allowed values: claude codex

baseUrl

custom only: the https base URL as the engine’s CLI means it (Claude: the API root, no /v1; Codex: the root /responses is appended to). No userinfo, query or fragment. An internal connection may use http.

string

>= 1 characters <= 2048 characters

region

Bedrock only: one AWS region id.

string

>= 1 characters <= 32 characters

transport

Bedrock only: runtime (Claude Code, Codex) or mantle (Codex only).

string

Allowed values: runtime mantle

internal

custom only: “Internal network”, an endpoint reachable only inside your own network (a LAN or private-network gateway). Workspace connections only (scope: "org", added by someone holding connections.org.write). Saved by hand: nothing calls it at save, models are typed, and it runs only on an owned runner serving the workspace. Can’t change on a reconnect.

boolean

secret

required

The provider key. Write-only.

string

>= 1 characters <= 8192 characters

boolean

reason

required

Why a discover or test failed. The only failure detail that ever leaves the sign-in box; never a provider’s response body.

string

Allowed values: unreachable private-address unauthorized forbidden model-not-found wrong-protocol rate-limited timeout upstream-error invalid-models expired unsupported

400

BAD_JSON — the body is not valid JSON, or INVALID_REQUEST — the decoded body does not match the route’s request schema.
