Agent keys are scoped to a mailbox and read/send permissions. - POST /v1/mailboxes returns mailbox information and an initial agent key. - POST /v1/mailboxes/{mailboxId}/messages requires Idempotency-Key. HTTP 202 means queued, not delivered. - Poll GET /v1/events with a persisted after cursor. Customer-configurable push webhooks are not currently available. - Reply through POST /v1/mailboxes/{mailboxId}/messages/{messageId}/reply. - Scargo is not a Gmail/Outlook account provider, OAuth mailbox connector, SMTP/IMAP service, or autonomous agent runtime. - No published SDK package, MCP server, or outbound attachments yet. - Custom domains: account keys can add /v1/domains, prove DNS ownership, and check provider sending/receiving records. Pass domain_id when creating a mailbox after both directions are verified. Provider activation is required for mail DNS and delivery. - Workflow decisions, extraction, approval, and task state belong to the integrating application. Public documentation reviewed: 2026-09-11.
