orbit Web Tools

Web utilities for agents, computed live at call time: URL health/redirect/x402 check, web page to Markdown (robots.txt honoured), DNS lookup with SPF/DMARC, email address validation (MX, disposable, role, typo), HTTP security-header audit and AI-agent readiness audit (llms.txt, AI crawler rules, x402, MCP, OpenAPI). $0.001 per call.

Skills

• URL health check ($0.001 via x402)
  Is a URL up? Live GET from Cloudflare's edge: final HTTP status, every redirect hop with status and latency, total ms, content-type/length, server, TLS, and if it answers 402 the decoded x402 payment terms (version, network, amount, payTo, bazaar). Unreachable host is still a delivered verdict (up:false).

• Web page to Markdown ($0.001 via x402)
  Fetch a public web page and return LLM-ready Markdown: title, meta description, canonical, language, main content (scripts/nav/footer stripped, headings/lists/links kept), first 50 absolute links, word count. Honours robots.txt (disallowed → 403, not charged). No JS rendering; non-HTML → 415. max_chars 500-50000 (default 20000).

• DNS lookup ($0.001 via x402)
  Live DNS records for a domain via DNS-over-HTTPS (1.1.1.1): A, AAAA, CNAME, MX, NS, TXT, CAA, SOA, or type=ALL for all of them plus parsed SPF and DMARC policy. Returns rcode (NOERROR/NXDOMAIN), records with TTL, DNSSEC AD flag.

• Email address check ($0.001 via x402)
  Validate an email address without sending mail: RFC syntax, domain MX (falls back to A), null-MX, disposable-domain list, role account (info@, support@…), free provider, typo suggestion (gmial.com → gmail.com), SPF/DMARC presence, and a verdict valid/risky/invalid with reasons. Does not probe the mailbox.

• HTTP security headers audit ($0.001 via x402)
  Audit a site's HTTP security headers live: HSTS (max-age, preload), CSP (unsafe-inline/eval flags), X-Frame-Options/frame-ancestors, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/CORP, cookie Secure/HttpOnly/SameSite flags, server/version leaks, HTTPS redirect. Score 0-100, grade A+-F, list of fixes.

• AI-agent readiness audit ($0.001 via x402)
  How ready is a website for AI agents? Live checks of /llms.txt, robots.txt rules for 12 AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot…), sitemap.xml, /.well-known/x402 and x402 402 answer, /openapi.json, MCP (/mcp, /.well-known/mcp.json), A2A agent card, security.txt. Score 0-100 with findings.
