HTTP Headers Analyzer API

Analyzes HTTP response headers from any URL and returns structured security data: CSP, HSTS, X-Frame-Options, and other protection headers, plus cache directives and server fingerprinting. Exposes a single tool that fetches a page and parses the headers into categorized findings. Operates over SSE transport and integrates x402 micropayments, meaning each analysis call costs a small amount. Useful when you need to audit header configurations across multiple domains, check if security policies are properly set, or automate reconnaissance tasks that would otherwise require manual curl inspection. The hosted API endpoint means no local dependencies beyond the MCP connection.
