domain_check_v1
Measures how resilient a public web domain is from the outside and returns a weighted score out of 100, a per-category breakdown, and prioritised findings explaining what to fix first. Use it to audit a domain you do not control, to verify a fix after deployment, or to compare several domains on the same scale. Covers TLS certificate validity and protocol version, HTTP to HTTPS redirection, HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, cache directives, response time, DNS redundancy, IPv6 availability, CDN detection and software version disclosure. Everything is read from the public internet: nothing is authenticated, no ports are scanned, and no credentials are needed. Do not use it for private, internal, or localhost hostnames, for IP addresses, or to test a service you need logged-in access to. For a free score without the detailed findings, use domain_check_score_v1 instead. Price: $0.01 per call (x402, USDC on Base). No signup, no API key. Price: $0.01 per call (x402, USDC on Base).

domain_check_score_v1
Free. Returns the overall resilience score out of 100 for a public web domain, plus the score of each category and how many findings each one raised. Use it to triage: to rank a list of domains, to confirm a domain is healthy, or to decide whether the detailed report is worth pulling. It tells you which categories are weak and how many issues they hold, but not what the issues are. For the individual findings and the prioritised remediation list, use domain_check_v1.
