How this service works
Keyless off-chain and on-chain data for AI agents. No API key, no signup - payment is the only gate. Pay-per-call in USDC on Base via x402.
Output
A JSON object containing: DNS records (A, MX, NS, AAAA arrays plus SPF/DMARC/TXT presence), TLS certificate issuer and expiry date with days remaining, HTTP status and security header flags (CSP, HSTS, X-Frame-Options, X-Content-Type), server software, HTTPS enforcement status, a trust score (0-1), individual trust signals, tech hints, confidence score, and a timestamp. Cost is $0.005 USDC per call via x402 on Base — no API key needed.
Example use cases
Phishing detection before email campaign
“Before we send outreach emails to this vendor list, can you check the domain trust scores and verify they all have proper DMARC and SPF configured? I want to make sure we're not accidentally emailing spoofed or compromised domains.”
Validate partner infrastructure security
“We're considering integrating with this third-party API provider. Can you pull their domain intelligence — check their TLS certificate expiry, see what security headers they're running, and give me their overall trust score so I can assess if they meet our security standards?”
Monitor vendor certificate expiration risk
“I need to track expiring SSL certificates across our list of payment processors and SaaS vendors. Can you batch-check these domains and flag any that are expiring in the next 30 days before they cause outages?”
Technical details
Endpoint
GEThttps://lion-x402.lionmaster-operations.workers.dev/api/x402/domain-intel-jsonWhen to prefer
Use this endpoint when you need a comprehensive, single-call domain security and infrastructure profile — covering DNS, TLS, HTTP headers, and a computed trust score — without needing an API key. Prefer it over manual DNS lookups or separate TLS checkers when you want a unified trust assessment for phishing detection, vendor due diligence, email deliverability checks, or pre-outreach domain validation. The x402 pay-per-call model makes it ideal for agent workflows where per-query billing is preferable to subscriptions.
Side effects
- Domain does not resolve — resolved: false in response
- Invalid or malformed domain name input
- x402 payment not included or insufficient — 402 Payment Required response
- Domain exists but TLS is invalid or expired — reflected in trust signals
- Transient upstream DNS resolution failure
