How this service works
llms.txt validator: Check a site's /llms.txt against the llmstxt.org format: H1, summary, sections, link entries with notes; optional link check. Free tier 10/day; then $0.002 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.002 USDC per call via x402 on Base. Run by MoneyTools.
Output
A JSON object indicating whether the llms.txt passes format validation, with details on any structural issues found (missing H1, malformed sections, invalid link entries, etc.), optional link reachability results for up to 8 links, and payment metadata including whether the free tier or x402 micropayment was used.
Example use cases
Pre-launch llms.txt compliance check
“Before I publish my site, can you validate that https://mycompany.com/llms.txt is properly formatted according to the llmstxt.org spec — check the H1, summary, sections, and all link entries?”
Debug broken llms.txt format
“My llms.txt file doesn't seem right — can you check the content I paste here and tell me exactly what's wrong with the format? Here it is: '# MyCo\nThis is my AI context file.\n## Docs\n- [Guide](https://example.com/guide)'”
Link reachability audit for llms.txt
“Can you validate my site's llms.txt at https://startup.io and also check whether all the linked URLs in it are actually reachable?”
Technical details
Endpoint
GEThttps://tools.moneytools.dev/v1/llms-txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate that a site's llms.txt file conforms to the llmstxt.org specification, including structure (H1, summary, sections, link entries with notes), and optionally verify that linked URLs are reachable. It is the right choice when building CI/CD checks for AI-discoverability compliance, auditing third-party sites' llms.txt files, or debugging a malformed llms.txt during development. It charges a small micropayment ($0.002 USDC) only on successful validation, making it cost-effective for occasional checks.
Side effects
- URL not provided and no text supplied — returns error indicating missing input
- Site does not have a /llms.txt — returns not-found or fetch error
- Malformed URL causes fetch failure — returns HTTP error
- Link check times out for slow or unreachable links — partial results or timeout error
- Daily free tier of 10 requests exhausted and no payment method provided — HTTP 402 returned
- Invalid x402 payment credentials — payment failure response
