Domain DNS, registration age and email authentication

$0.005 per call · failed calls are never charged · no account or API key needed

Domain intelligence in one call: DNS records (A, AAAA, CNAME, MX, NS, TXT, CAA), DNSSEC status, registrar, registration and expiry dates with domain age in days (RDAP/WHOIS), and email authentication (SPF and DMARC records and policies, whether the domain accepts mail). Use for lead qualification, phishing and trust checks, and deliverability audits.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/domain?name=cloudflare.com"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/domain?name=cloudflare.com&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.
