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

POST
/connections/ai-accounts/custom/discover

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

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.

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

Successful response.

Any of:

Model ids as the endpoint returned them, kept verbatim.

SCOPE_REQUIRED — the x-uai-org scope names a workspace that does not exist, or one the caller is not a member of. The two are deliberately indistinguishable: a 403 would confirm the workspace exists.
