How this service works
Pay-per-call JSON tools for AI agents: Indian identifier validation (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID, vehicle registration), AI-visibility (GEO) audits, AI crawler robots.txt matrices and llms.txt checks. x402 (USDC on Base) or RapidAPI.
Output
Returns a JSON object with the domain's origin URL, an overall status ('missing', 'valid', or 'invalid'), and a detailed llmsTxt object containing: whether the file is present, whether it's valid, a list of format issues, the title, parsed sections, and link count. Also reports whether llms-full.txt is present.
Example use cases
Verify own site's AI discoverability
“Check if my website anthropic.com has a valid llms.txt file and let me know what issues, if any, are found with the formatting.”
Competitor AI visibility audit
“Does stripe.com have an llms.txt file, and if so is it properly formatted according to the spec?”
Pre-launch llms.txt compliance check
“I just published an llms.txt on mybrand.io — can you verify it's valid and tell me the title, how many links it has, and whether llms-full.txt is also present?”
Technical details
Endpoint
GEThttps://setu.xyz23110928.workers.dev/v1/llms-txt/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a specific domain has published an llms.txt file and whether it meets the spec, especially for AI agent workflows auditing AI-crawler readiness or content discoverability. It is purpose-built for the llms.txt standard and returns structured validation details, unlike generic HTTP HEAD checks.
Side effects
- Domain does not exist or is unreachable — status may show 'missing'
- llms.txt present but malformed (e.g. missing H1 heading) — status 'invalid' with issues listed
- Network timeout fetching the domain's file
- Invalid or missing 'domain' query parameter returns an error
