Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"lordevo-shop","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

What the publisher says
Attributed to the source that supplied each field. Treated as claims, not facts.
Pay-per-call website and domain checks for AI agents (x402, USDC on Base), $0.01-$0.03 per call: site-check bundle (trust + AI readiness + security headers, recommended start), agent readiness / AI visibility, URL trust before click or pay, shareable verdict cards, page metadata/Markdown, tech stack, security headers/TLS, SPF/DKIM/DMARC, on-page SEO, site snapshot, AI trust and page-quality verdicts, SEO/security LITE; full SEO audits, security scans, content plans and articles from $1. A2A message/send at /a2a is free: it names the right check with its endpoint, price and x402 payment terms.
Find the right check, its price and payment terms (free) — Free. Send what you want to check (a tool name and/or a URL, domain, email or IP) and get back the matching paid check with its exact HTTP endpoint, MCP call, price and live x402 terms; or "sample <tool>" for a free example output. Nothing is charged over A2A.
Site check: trust + AI readiness + security headers (recommended start) — $0.03 per call. One call answers both questions agents ask about a website: can I trust or pay it (url-trust: TLS, redirects, domain age via RDAP, lookalike/punycode, scam/parked signals, x402 challenge validity) and is it ready for AI agents and search (agent-readiness score 0-100), plus a security-headers summary. Returns overall verdict, scores, top fixes and the three full sub-results.
Agent readiness / AI visibility score (GEO) — $0.03 per call. Scores how visible and usable a site is for AI assistants and agents (0-100, grade A-F): robots.txt rules for AI search and training crawlers (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended...), noindex/noai, /llms.txt quality, schema.org JSON-LD, sitemap, title/description/canonical/lang, Open Graph, content readable without JavaScript, and agent discovery files (/.well-known/x402, MCP server card, A2A agent card, OpenAPI). Findings with fixes. Obeys robots.tx…
URL trust check before you click or pay (safe / caution / risky) — $0.01 per call. Pre-click / pre-pay check of one URL: TLS validity and expiry, redirect chain (HTTPS downgrades, cross-domain hops), domain age via RDAP, brand lookalike and punycode/mixed-script signals, parked or scam-pattern content, seed-phrase or lookalike login forms, security-header grade, and, if the URL answers 402, whether its x402 challenge is valid (USDC on Base, payTo, amount, resource host). Verdict safe/caution/risky with reasons. No third-party blocklist.
Can I fetch this URL? robots.txt + AI-crawler permission gate — $0.01 per call. Pre-fetch gate for agents and scrapers: is this exact URL allowed by robots.txt (RFC 9309: missing = allow, 5xx/unreachable = disallow) for generic agents and 16 named AI agents/crawlers (ChatGPT-User, Claude-User, PerplexityBot, GPTBot, ClaudeBot, Google-Extended, CCBot...), plus Crawl-delay, Content-Signal (search / ai-input / ai-train), X-Robots-Tag noai/noindex from a HEAD request, and sitemaps. Verdict allowed / disallowed / allowed_but_no_ai_use / allowed_with_crawl_delay.…
Link check: is it alive, where does it really go (redirects resolved) — $0.01 per call. Resolve one link the way a browser would: follows up to 10 redirects (HEAD first, GET fallback), returns alive true/false with a reason (http_404, dns_not_found, timeout...), the final URL and domain, every hop with its status, cross-domain and HTTPS-downgrade flags, URL-shortener detection, content type/length, Last-Modified/ETag, X-Robots-Tag and TLS validity. Dead links are an answer, not an error. Cached up to 5 min. ~0.3-3 s.
