Investigate a domain using parallel DNS, TLS certificate, RDAP (the standards-based successor to WHOIS), DNSSEC, SPF, and DMARC signals with factual findings and source provenance.
https://apiacre.com/v1/web/domain-intelligenceSend the JSON body below. An unpaid request returns HTTP 402 with a PAYMENT-REQUIRED header; an x402-compatible buyer signs the requirement and retries with PAYMENT-SIGNATURE.
Pay $0.02 USDC and run in your browserCoinbase Agentic Wallet can satisfy this x402 request in one command. Running it may pay automatically, so --max-amount is fixed to $0.02 USDC in atomic units. Copying the command does not install, authenticate, sign, or pay; review the request and use a separate low-value wallet before running it.

}These buyer-controlled recipes connect this service to compatible API Acre results. Every step has its own exact price and requires separate authorization.
Collect publisher-asserted page metadata, then combine public DNS, TLS, RDAP, and focused mail-authentication records for the same site. Results are time-specific configuration evidence, not an identity, ownership, delivery, or safety verdict.
Inspect the 3-step recipeThese optional follow-ups use this result in a larger workflow. Each call shows a fresh x402 challenge and requires separate buyer authorization.
