How this service works
Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.
Output
A JSON object containing: a 0–100 composite score, the audited domain name, a breakdown of points across four sub-categories (tls, mail_auth, web_hygiene, mail_delivery), a human-readable verdict (e.g. 'acceptable'), and an array of specific findings explaining what passed or failed (e.g. 'DMARC policy reject', 'null MX').
Example use cases
Pre-send cold outreach check
“Before I launch this cold email campaign, audit deliverability for hubspot.com — I need to know if their DMARC policy will reject our emails and what their overall score is.”
Vendor domain trust verification
“I'm about to onboard a new vendor whose invoices come from paymentsco.io — can you audit that domain for mail authentication and TLS so I can see if it looks legitimate?”
Own domain health check
“Audit my company domain acmecorp.com and tell me the score out of 100, what's failing, and whether the verdict is acceptable so I know what to fix before our next email blast.”
Technical details
Endpoint
GEThttps://xhagents.xyz/api/domain-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, scored audit of a domain's email deliverability and security posture — specifically covering TLS, DMARC/SPF/DKIM, MX configuration, and web hygiene — in a single $0.05 call with no API key. Prefer it over manual DNS lookups when you need a machine-readable verdict and score suitable for automated decision-making.
Side effects
- Invalid or non-existent domain returns an error or zero score
- DNS lookup timeout for domains with slow resolvers
- Domains with no MX records may return null MX finding rather than an error
- Missing DMARC/SPF records scored as 0 in mail_auth sub-category
- Payment failure via x402 if wallet has insufficient USDC
