How to authenticate
Checked against the endpoint by our probe on 8 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | OAuth |
|---|---|
| Issuer | https://api.hatchloop.dev |
| 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, refresh_token |
| Scopes | agentbroker.tools, offline_access |
| Protected-resource metadata | ✓Published (RFC 9728) |
| Anonymous access | Handshake succeeds; 23 tools listable |
| Credentials demanded in prose | ✕import_booking_url 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. |
| Documentation | https://hatchloop.dev/agents.md |
What the probe found
1 of the 23 tools listed anonymously say in their own descriptions that they need an account or a key (import_booking_url), 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.
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.
The server exposes a public surface before authorization: find_business, verify_business, send_message, capture_lead, schedule_appointment, send_transactional_confirmation, handle_inbound, escalate_to_human, get_status, get_outcome, preview_cost, self_test, check_quota, check_booking_link, import_booking_url, call_business, check_compliance, verify_company_record, screen_sanctions, map_trade_restriction, get_conversation, mint_key, lookup_us_contracts.
