## Tools
- domain_check_batch_v1 (Domain Resilience Check, Batch) - Runs the full resilience check on up to 100 domains in a single call and returns the same scored report for each one: TLS certificate, security headers, DNS redundancy, response time, with every individual finding. Use it to audit a portfolio, to rank a list of vendors, or to re-check a fleet after a config rollout. One payment covers the whole batch instead of one per domain, which is why it is both cheaper per domain and much faster than calling domain_check_v1 in a loop. A domain that cannot be reached is returned with its own error rather than failing the batch, and it is still charged, because the crawl was attempted. Do not use it for a single domain: domain_check_v1 is simpler and costs the same for one. Private, internal and localhost hostnames and IP addresses are rejected. Price: $0.01 per domain, dropping to $0.005 from 100 domains, up to 100 per call. One payment covers the whole batch (x402, USDC on Base). No signup, no API key. Endpoint: https://www.feranor.com/mcp
- domain_check_v1 (Domain Resilience Check) - 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. Endpoint: https://www.feranor.com/mcp
- domain_check_score_v1 (Domain Resilience Score) - 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. Free, no payment required. Endpoint: https://www.feranor.com/mcp
