}Call this endpoint with the verified account session created during user account setup. That session is the bootstrap path for the first application, so no existing API key is required. A user-scoped OAuth grant or compatible user-bound key can also manage applications. See the Developer guide for the complete endpoint and credential map.
Registering an application does not authorize access to an end user; that requires their scoped Darwin OAuth grant.
Authorizations
AccountSessionapiKeybearer
The HTTP-only Darwin account session cookie set after sign-in. Local development uses better-auth.session_token without the __Secure- prefix.
Body
application/json
Response
The application was registered.
