How this service works
Tech-stack / DNS / TLS intel for a domain: DNS records (A/AAAA/MX/TXT/NS) via DNS-over-HTTPS, TLS certificate issuer + expiry via crt.sh, server headers and detected stack hints via direct HTTPS probe. Paid per call: $0.01 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453) via x402 v2 (exact scheme, EIP-3009). Unpaid requests return HTTP 402 with machine-readable payment instructions; the buyer signs the EIP-3009 authorization off-chain and retries with the PAYMENT-SIGNATURE header. The facilitator pays the gas, so the buyer needs no ETH. No API key.
Output
A JSON object containing: DNS records keyed by type (A, AAAA, MX, TXT, NS), TLS certificate issuer and expiry timestamp plus days remaining, HTTP response status and detected stack hints (e.g. 'cloudflare', 'nginx'), the queried domain, service name, and a Unix timestamp of when the check was performed.
Example use cases
Pre-acquisition domain due diligence
“Before we finalize the acquisition of acme-widgets.com, can you check its DNS setup, TLS certificate issuer and expiry, and what web stack it's running so we know what we're inheriting?”
Certificate expiry monitoring alert
“Check the TLS certificate for api.mycompany.com and tell me how many days are left before it expires — I need to know if we're at risk of it lapsing.”
Competitive tech stack research
“I'm curious what infrastructure competitor.io is running — can you look up their DNS records and detect what server software or CDN they're using?”

Endpoint
GEThttps://stack-intel.hsharmanov02.workers.dev/intel?utm_source=zero.xyzWhen to prefer
Choose Stack Intel when you need a fast, all-in-one domain intelligence snapshot combining DNS records, TLS certificate health, and server/CDN detection in a single call without managing multiple DNS APIs, crt.sh queries, and HTTP probes separately. Ideal for security audits, pre-acquisition due diligence, certificate expiry monitoring, or competitive tech research. Prefer this over DIY approaches when you want no API-key setup and are comfortable with micro-payment per call via x402/EIP-3009 on EVM chains or Solana.
Side effects
- HTTP 402 returned if no payment is attached — includes machine-readable EIP-3009 payment instructions for retry
- Domain not found or unreachable — DNS or HTTP probe may return empty or partial results
- TLS lookup via crt.sh may lag for very new certificates not yet indexed
- Invalid or malformed domain input may return an error response
- Network timeout on direct HTTPS probe for slow or unresponsive servers
