Mail Security Tools
api.
Get the exact SPF, DKIM and DMARC records to publish, with steps for your DNS host. $1 USDC on Base per call. Reads live MX, NS, SPF, DKIM and DMARC, detects the mail provider and DNS host, and returns records in order with a staged DMARC rollout. Non-sending domains get a lock-down set. Bad input 400, unknown domain 404, not charged. Don't use this for a quick grade; use /v1/score.
