Email & messaging

Use when you need to judge whether a website or email domain is trustworthy: registration date and domain age (RDAP), expiry, registrar, nameservers, email setup (MX, SPF, DMARC), disposable-email domains, and a low/medium/high risk with flags such as 'registered 4 days ago', a common sign of scam shops. Accepts a domain, URL or email.

Use when an agent must check a domain: does it resolve, who hosts its DNS and mail, is email authenticated, how old is it, when does it expire. Input: domain (e.g. example.com; URLs accepted). Output: JSON DNS records (A, AAAA, CNAME, MX, NS, TXT, CAA, SOA), mail provider, parsed SPF and DMARC, DNS provider, and RDAP registration (registrar, created, expires, age in days, status, DNSSEC). No contact data. Example: ?domain=google.com

MX records, SPF and DMARC check of a domain: does it accept email, its mail servers, SPF policy, DMARC policy and detected deliverability issues. DNS only, no SMTP.

Website technology detection: CMS, e-commerce platform, analytics, tag managers, CDN, hosting, chat, payments, A/B testing, consent tools and the e-mail provider, each with version, confidence 0-100 and evidence, from 231 own fingerprints over the home page, headers, cookies and the domain's MX/TXT records. For lead filtering and competitor research.

Domain Intel ($0.012): domain identity & trust posture in one call — RDAP registration data (registrar, creation/expiration/last-changed dates, status, nameservers, or a clean not-registered result), live DNS email-authentication read (MX/SPF/DMARC/NS), and a heuristic posture summary (e.g. newly-registered + no SPF/DMARC = elevated impersonation risk). Fetched live from IANA's RDAP bootstrap + the TLD registry's own RDAP server, and this server's own DNS resolver (no third-party DoH relay).…

Post a message on a public notice board. POST JSON {"message": "..."} up to 280 characters; after payment it appears at /board, newest first, with the payer address and time, kept for 30 days. An effect, not a data lookup. No moderation beyond length; illegal content is removed.

Verify email syntax and public DNS readiness with a bounded deterministic preflight. Forest checks normalized syntax, MX/address records including explicit null MX, and curated role/free/disposable-domain signals, then returns a conservative safe-to-attempt decision. It never connects to SMTP, sends mail, authenticates, stores customer mailboxes or claims that a mailbox exists. Base mainnet USDC

Text classification with your own labels for agent pipelines: route support tickets, qualify leads, tag feedback, sort emails or moderate comments. Send the text (up to 6,000 characters) and 2 to 30 labels, optionally with a description each; get the best label with a confidence from 0 to 1 and a one-sentence reason, or every label that applies with multi_label. Labels are enforced by a JSON schema, so the answer is always one of yours. Any language. Instructions inside the text are ignored.

Verify an email address: check its syntax and DNS (MX) to see whether it can receive mail, no SMTP. Input: email. Returns a verdict, MX hosts and disposable, role and free-provider flags. Use when an agent must decide whether an email address looks deliverable before sending or storing it.

Generate deterministic fake test rows from a field->type spec plus a seed (names, emails, phones, addresses, dates, ints, bools). Output JSON, CSV, or NDJSON. Same seed always yields the same data -- reproducible fixtures.

Send one SMS to a mobile number, paid per message in USDC with x402. Use it when an agent must notify a person by text. The 402 quotes the exact price for the destination and message length. No account and no API key: any wallet that pays sends in one call. An opt-out link is appended to the message, and numbers that opted out are refused. Returns an order; poll GET /v1/orders/{id} for delivery status.

End-to-end email-auth report for a domain: SPF + DMARC + DKIM (probes common selectors automatically) + MX records + score 0–100. The one call to make when 'why is our mail going to spam?' lands in your inbox.

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…
