Record calls to your own API (Telltale for APIs)
POST /api/v1/api-calls · operationId recordApiCalls
For developers: your server sends this request with a server key; it is not a button in the dashboard. To see the same information without code, open Tools › All tools in the dashboard.
Shapes only: unknown fields are refused, never dropped, so no body, query value, header or credential can be stored. A call with agent evidence (agent token, Web Bot Auth signature, a declared name checked against its operator's IP list, an AI agent provider's published IP range, or a declared name) is one approved-route call with channel api, once per eventId; every other call is Unknown (never Human) and only counted per route and day. Sent by the API middleware (/adapters/v1/api.js; see Telltale for APIs).
Authentication
Send Authorization: Bearer YOUR_SERVER_KEY (siteServerKey: Site server key in Authorization: Bearer <key> (the scheme is case-insensitive and required; a bare key is 401). Shown once on creation or rotation. Publishable keys cannot authenticate). Keep the server key in server-only configuration; never send it to a browser.

Failures are not verdicts. Error bodies follow the Error schema: code is one of bad_request, unauthorized, session_reinit_required, forbidden, not_found, conflict, identity_required, payload_too_large, rate_limited, internal_error, service_unavailable, request_failed, approval_invalid, approval_used, approval_expired, approval_mismatch, step_up_not_held, step_up_mismatch, step_up_settled, step_up_expired, step_up_superseded, agent_tokens_disabled, tool_not_approved, tool_not_read_only. Errors and retries explains each code and what to do.
