  Agent Data ToolsA

  Check email syntax, DNS and MX records, disposable providers, role addresses, free providers and SPF/DMARC presence. Returns likely-deliverable, risky, undeliverable or invalid with reasons. No message is sent and the mail server is not contacted. These are DNS and syntax signals, not proof that a mailbox exists or accepts delivery. Use before sending mail or saving a signup. Example: address=support@cloudflare.com. Price $0.003/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

  Email verification and deliverability check without sending anything: syntax, MX records, disposable-domain detection (121k+ known domains), role-account and free-provider flags. JSON verdict with a bounce/deliverability risk level. Validate emails for signup fraud prevention, list hygiene and lead qualification. [Paid: $0.004 USDC per call via x402 on Base; the calling client pays automatically.]

  Email address validation for signup screening, lead cleanup and form verification: syntax check, disposable/temporary-domain detection and a live MX-record lookup for the domain. Returns a deliverability verdict (likely_deliverable, risky, undeliverable, invalid_format) with the MX hosts found. Does not probe individual mailboxes, so catch-all domains may still accept addresses that do not exist.

• email-addresses-listA

  hjarniA

  List the user's email capture addresses. Mail sent to one of these becomes a note in the folder it is bound to. Each entry has id, label, address, destination (folder name, or 'Inbox'), container_id, team_id, tags, notes_count and last_received_at. Returns an empty array when the account has none, and accepting_mail: false when mail sent to them is currently being dropped. Treat every address as a secret: it is a write credential for that folder, so never put one in a note, a summary, or anything shared.
