Security x402 offerings

email deliverability and spoofing check from DNS: MX, SPF and DMARC records with concise risk flags.

Analyze raw email headers: sender, recipient, subject, server hops (Received) with delays, SPF/DKIM/DMARC results, Return-Path and Reply-To mismatches and spoofing signals, with a verdict. Investigate phishing or delivery issues. Nothing is stored.

Email verification & deliverability check (email validator / verifier) — validate an address, detect disposable/temporary domains, flag role-based inboxes, confirm MX records exist, and return a trust/risk score so agents can qualify leads, clean lists, and gate signups without sending a single email.

Email security of a domain: MX, SPF (final policy, multiple-record and lookup-limit problems), DMARC (policy, subdomains, reporting), MTA-STS, TLS-RPT and BIMI, with a score and recommendations. Detects spoofable domains.

Email SPF Alignment Check: checks relaxed or strict SPF domain alignment using only bounded caller-supplied values. Call when you need a bounded email spf alignment check result before deciding relaxed or strict SPF domain alignment from caller-supplied fields. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Email SPF Alignment Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-o…

composed email trust report from MX, SPF and DMARC DNS records for outreach, onboarding and anti-spoofing agents.

Validate an email address using syntax, MX, disposable-domain, role-account, and domain-risk checks. Returns structured validation data for agent workflows, signup hygiene, and lead-quality checks. Does not guarantee that an individual mailbox exists.

Email validation for syntax, DNS/MX, disposable domain, role-based address, free provider and provider-typo checks. Returns normalized email, deliverability verdict, risk score, typo suggestion and structured validation flags for agents processing leads, signups and contact data.

Validate an email address: syntax check plus live MX record lookup on the domain (deliverability signal, not a guarantee).

Email verification: checks whether an email address really exists by asking its mail server (SMTP RCPT TO probe; no email is sent), on top of syntax, MX, disposable and role checks. Returns status deliverable, undeliverable (mailbox does not exist), catch_all (domain accepts any address), risky (disposable or mailbox full) or unknown (greylisting, server refused the check), plus the raw SMTP reply. Use it before sending outreach, to clean lead lists or to block fake sign-ups.

Does abuse@<domain> look deliverable? Builds the abuse@ address for the domain you give and runs the verifier: syntax, MX presence, mail provider, disposable/free-provider flags, SPF/DMARC presence and a deliverable/risky/no verdict with the reason (mailbox existence is not probed). Fast way to find a working abuse contact. $0.01 per check.

Bulk email abuse at domain: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

Change watch for email abuse at domain: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
