How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object indicating whether the call succeeded and payment was accepted, along with DMARC record details such as the policy mode (none, quarantine, reject), reporting addresses, and other DNS record fields for the queried domain.

Example use cases

Pre-send domain security audit

“Before we start our email campaign, can you verify that our domain marketing-co.com has a proper DMARC record set up and what the policy is?”

Vendor email security vetting

“I'm about to share sensitive documents with someone from supplier-corp.com — can you check whether their domain has DMARC configured so I know their email isn't easy to spoof?”

Competitive email security benchmarking

“Can you look up the DMARC records for bigbank.com, creditunion.org, and fintech-startup.io so I can see how their email security policies compare?”

When to prefer

Use this endpoint when you need a quick, no-signup DMARC lookup paid per-call via USDC over x402 — ideal for AI agents that need to check email authentication policy without maintaining API key credentials. Prefer this over manual DNS lookups when automating domain security audits at scale.

Side effects

Domain has no DMARC record published — returns empty or not-found result
Invalid or malformed domain name input causes lookup failure
DNS resolution timeout for the queried domain
Payment failure via x402 protocol prevents call from completing
Misconfigured schema parameter returns unexpected format
