No status page, SLA, changelog, idempotency key on send or official SDK was found, and SOC 2 is not yet held.\n\n**Gmail API.** Fourteen OAuth scopes separate labels, sending, metadata and read-only access, and the quota page gives every method a unit cost. Eight of the scopes are restricted, read-only and metadata among them, so a public app that reads mail needs Google's verification and an annual third-party security assessment. Gmail mailboxes only.\n\n## Before you call either\n\n### Aurinko Email API\n\n1. Use `https://api.aurinko.io/v1`. Several cURL examples in the docs print `https:/api.aurinko.io` with one slash, and one search example names the host `asti.aurinko.io`\n2. Do not retry `POST /v1/email/messages` blindly after a timeout. There is no idempotency key, so check Sent mail with `q=rfc822msgid:` or by subject first\n3. Call `POST /v1/email/sync` until `ready` is true, then page `/v1/email/sync/updated` with `pageToken` until a `nextDeltaToken` appears and store it\n4. Check the `omitted` array on message lists. Full bodies come only from Google and Office 365, and other providers return a snippet\n5. Request `Mail.Read` plus `Mail.Send` for read and send without modify rights. The docs example names `Mail.ReadOnly`, which is not in the scope list\n\n### Gmail API\n\n1. Ask for the narrowest scope. `gmail.labels` is non-sensitive and `gmail.send` is sensitive, while every scope that reads mail is restricted\n2. List with `messages.list` and `q` in Gmail search syntax, then fetch each ID with `format=metadata` or `full`. List calls return IDs only\n3. Send by posting an RFC 2822 message, base64url encoded, in `raw`. Set `threadId` and matching reply headers to stay in a thread\n4. Store the `historyId` and call `history.list`. On a 404, run a full sync. Call `watch` again at least every 7 days\n5. Back off exponentially on 403 and 429 rate errors, and keep batches to 50 requests or fewer\n\n## Questions\n\n### Which is better for AI agents, Aurinko Email API or Gmail API?\n\nGmail API scores 77.8 (BB) on agent readiness against Aurinko Email API's 44.2 (E), and leads in 6 of 7 scored categories. Aurinko Email API leads on payments \u0026 pricing.\n\n### Do Aurinko Email API and Gmail API need an API key?\n\nBoth use an OAuth sign-in.\n\n### Can an agent call Aurinko Email API and Gmail API without installing anything?\n\nYes. Aurinko Email API has a hosted endpoint at https://api.aurinko.io and Gmail API at https://gmail.googleapis.com/gmail/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/aurinko-email-vs-gmail-api.json, and with the fewest tokens: https://www.anchorterminal.com/compare/aurinko-email-vs-gmail-api.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"aurinko-email\", \"b\": \"gmail-api\"}`.
