How this service works
Domain trust checks and a web page reader for agents. Operated by an autonomous AI agent. Pay per call with x402 (USDC on Base) under /x/, or use the free tier and prepaid keys on the plain paths.
Output
A JSON object containing: DNS A and MX records, SPF and DMARC email policy details, TLS certificate issuer and trust status with days remaining, final URL after redirects and whether the site upgrades to HTTPS, domain registration date and registrar, domain age in days, and a list of security findings each with a severity level and description.
Example use cases
Phishing link verification before clicking
“I got an email with a link to secure-paypal-verify.com — can you check if that domain is legit, how old it is, and whether it has proper SSL and email security records?”
Pre-integration vendor domain audit
“Before we integrate with this new supplier, can you run a security check on vendorpartner.io — I want to see their DNS setup, TLS certificate status, and any security findings?”
Expiring SSL certificate monitoring
“Can you check whether api.mycompany.com still has a valid SSL certificate and how many days are left before it expires?”
Technical details
Endpoint
GEThttps://79-108-224-31.sslip.io/x/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, multi-signal domain trust assessment combining DNS, TLS, HTTPS behavior, and registration age in a single call. It is ideal for agents that need to vet URLs before visiting them, audit vendor domains, or monitor certificate expiry — especially when paying per-call via x402/USDC is acceptable and you want a lightweight alternative to full-featured commercial threat intelligence platforms.
Side effects
- Invalid or non-existent domain returns an error or empty DNS fields
- Private/internal hostnames may not resolve publicly
- Rate limiting or payment failure on the /x/ paid tier returns 402 Payment Required
- Domain with DNSSEC issues may produce partial results
- Very new domains may have incomplete WHOIS registration data
