How to authenticate

Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	OAuth
Issuer	https://api.keyframer.dev/api/auth
Dynamic client registration	✓Advertised (RFC 7591)
Client ID Metadata Document	✓Supported A client identifies itself by a URL to its own metadata, so no registration step is required.
PKCE	✓S256
Grant types	authorization_code, client_credentials, refresh_token
Scopes	openid, profile, email, offline_access
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 11 tools listable
Credentials demanded in prose	✕update_scene, list_scenes, get_scene, get_preview_qr, generate_code These tools are listed anonymously and their own descriptions ask for an account or key, but no challenge is issued — so a client has nothing to act on and the refusal arrives as a tool error.

What the probe found

warningTools needing credentials are listed without a challenge

5 of the 11 tools listed anonymously say in their own descriptions that they need an account or a key (update_scene, list_scenes, get_scene, get_preview_qr, generate_code), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.

No CORS headers for browser-based clients

A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.

11 tools usable without signing in

The server exposes a public surface before authorization: search_recipes, get_recipe, get_scene_format, validate_scene, sample_scene, create_scene, update_scene, list_scenes, get_scene, get_preview_qr, generate_code.
