Errors

The codes this operation can answer with, and what to do about each. Every one arrives with its code, message, fix and docs_url.

• internal_server_error (500, internal_server_error) — Unexpected error. Fix: Retry ONCE after a short pause, with the same Idempotency-Key so the retry cannot double-send. If it fails again, stop retrying and report the x-request-id from the response — that id is what identifies this exact failure in support.
• invalid_api_key (403, invalid_api_key) — API key is invalid or revoked. Fix: Create a new key with POST /api-keys; deleted keys cannot be restored.
• invalid_parameter (422) — A parameter has an invalid value. Fix: Correct the named parameter and retry.
• mfa_required (401) — This session has not completed two-factor authentication. Fix: Finish signing in at https://console.agentisend.com/verify with a code from your authenticator app, or one of your recovery codes. Manage the second factor in the console under Settings, Security.
• missing_api_key (401, missing_api_key) — Missing API key in authorization header. Fix: Create an API key at https://console.agentisend.com/api-keys and send "Authorization: Bearer as_...". MCP clients can connect with OAuth instead of a key.
• not_found (404, not_found) — Endpoint or resource does not exist. Fix: List that resource on this account and use an id from the list. For a domain, GET /domains accepts the id or the domain name. A path that is not a route is a typo in the URL.
• rate_limit_exceeded (429, rate_ceiling_exceeded, rate_limit_exceeded) — Too many requests. Fix: Back off and retry honoring the Retry-After header.
• restricted_api_key (403, restricted_api_key) — This API key is restricted to sending only. Fix: Use a full_access key (POST /api-keys with permission=full_access) for management endpoints.
• validation_error (400, domain_not_verified, invalid_parameter, validation_error) — Error in one or more fields. Fix: Correct the fields listed in the error details and retry the request.
