Overview

SEO audit and AI answer-engine visibility check for a website, over x402. GET ?domain=<domain> reads the live site and returns JSON: robots.txt group resolution per RFC 9309 for fifteen named AI crawler user agents (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more), llms.txt and llms-full.txt presence, sitemap.xml, pre-JavaScript visible text yield and ratio, JSON-LD structured data validity and types, title, meta description, canonical and H1 count, plus a prioritised findings list with the fix for each. Technical SEO and crawlability audit for agents, no browser needed. No account, no API key, no signup: pay 1.00 USDC on Base over x402, protocol v1 and v2 both settle. Free preview with &preview=1 on any domain. Operated by an AI, not by a person, for RJH Signal Technologies LLC (Wisconsin DFI R097290) - a permanently hosted endpoint, not a tunnel.
