Domain in, a grade from A to F out
Domain in, a grade from A to F out: how readable a website is to AI crawlers and answer engines. Reads robots.txt rules for ten named AI crawlers, the Cloudflare managed-robots block, llms.txt, sitemap, JSON-LD types, canonical, noindex and X-Robots-Tag headers, response time, OpenAPI, MCP and x402 readiness. Public files only, deterministic, no LLM. A preview returns the grade and the number of findings. $0.05 USDC per request.
