It is hosted on Railway and responds with a 402 Payment Required challenge, confirming it is live and expects x402-protocol payment before returning results.\n\nBased on the endpoint path, the service likely accepts a target URL and returns an analysis of its HTTP security headers — such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. Security header analysis is a common component of web application security audits and compliance checks.\n\nDocumentation is extremely sparse: no OpenAPI spec, no docs page, no README, and no pricing page were found. The x402 challenge was captured but contained an empty challenge object, so the exact payment token, network, and price are unknown. All functional details about request parameters, response format, and pricing are inferred from the endpoint path alone and should be treated with caution.","tags":[],"capabilities":["security-header-analysis","http-header-inspection","web-security-audit","x402-payment","pay-per-call"],"categories":["security","web"],"synonyms":["HTTP security headers","CSP checker","HSTS analyzer","security header scanner","web header audit","X-Frame-Options check","security headers test"],"warnings":["Empty x402 challenge object — payment token, network, and price are unknown","No documentation, OpenAPI spec, or README available","Request parameters and response schema are entirely inferred from the endpoint path","Root domain returns 404; no supporting pages found"],"endpointUrl":"https://netintel-production-440c.up.railway.app/security-headers/analyze","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xdaDc335482AD545296Fd7b28518A251fFCbEb9Df","amount":"1000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.200","qualityRationale":"The endpoint is live (402 response captured), but the x402 challenge object is empty, there is no documentation, no OpenAPI schema, no pricing information, and no crawlable content.
