How this service works
Live domain trust signals: DNS (MX/SPF/DMARC/A) + HTTPS probe via Cloudflare DoH. Keyless $0.005.
Output
A JSON object containing: DNS records (A, MX, NS, AAAA), SPF/DMARC presence, TXT record count; TLS issuer, expiry date, and days to expiry; HTTP server, status code, security headers (CSP, HSTS, X-Frame, X-Content-Type), HTTPS enforcement; a composite trust_score (0-1), confidence score, tech hints array, resolution status, asset_id, and as_of timestamp. Every response is Ed25519-attested for offline verification.
Example use cases
Example prompt
“Can you check the domain intelligence for stripe.com — I want to see its DNS records, whether it has SPF and DMARC, TLS certificate expiry, HTTPS enforcement, and its overall trust score?”
Technical details
Endpoint
GEThttps://lionx402.com/api/x402/domain-intel-jsonWhen to prefer
Choose this endpoint when you need a quick, verifiable snapshot of a domain's DNS health, TLS status, HTTP security posture, and trustworthiness in a single call — especially in agentic pipelines that require cryptographic attestation of the data. It is ideal for due diligence on vendors, counterparties, or leads, and for email deliverability pre-checks (SPF/DMARC). Pay-per-call USDC pricing makes it cost-efficient for spot lookups versus subscribing to flat-bundle infrastructure tools.
Side effects
- Domain does not resolve — resolved: false, confidence lowered
- Invalid domain format — likely 4xx error response
- Domain exists but has no MX/SPF/DMARC — fields present but false
- TLS certificate expired or missing — days_to_expiry negative or null
- Payment not included or insufficient — HTTP 402 response requiring x402 USDC payment on Base
- Rate limit or service unavailability — 5xx response
