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.1inch.com
Dynamic client registration	✓Advertised (RFC 7591)
Client ID Metadata Document	✕Not advertised
PKCE	✓S256
Grant types	authorization_code, client_credentials, refresh_token
Scopes	openid
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 10 tools listable
Credentials demanded in prose	✕authenticate, swap, orderbook, product_api, aqua, walletconnect, debug 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

7 of the 10 tools listed anonymously say in their own descriptions that they need an account or a key (authenticate, swap, orderbook, product_api, aqua, walletconnect, debug), 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.

10 tools usable without signing in

The server exposes a public surface before authorization: search, list_examples, get_example, authenticate, swap, orderbook, product_api, aqua, walletconnect, debug.
