How this service works
232 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.
Output
A JSON object containing the site URL, raw text of the llms.txt, parsed title, summary, an array of sections (each with a title and array of links with URL, link text, and description), total character count, total link count, and a boolean indicating whether llms-full.txt exists.
Example use cases
Discovering a site's AI-readable overview
“Fetch the llms.txt for openai.com and tell me what it says — the title, summary, and any sections or links it includes.”
Checking competitor AI discoverability
“Read the llms.txt for stripe.com and pull out all the sections and links so I can see what they're telling AI agents about their product.”
Verifying llms-full.txt availability
“Look up the llms.txt for huggingface.co and let me know whether they also publish an llms-full.txt, plus give me the full structured breakdown.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/llms-txt-read?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically read and parse a website's /llms.txt file into structured JSON rather than raw text. It is ideal when you want to understand what a site officially communicates to LLMs — its title, purpose summary, and navigational sections — without writing your own parser. Prefer it over raw HTTP fetching when you need clean structured output ready for downstream agent reasoning.
Side effects
- Site does not have an /llms.txt file — returns null or empty fields
- URL is malformed or unreachable — request fails with error
- Site blocks automated fetches — may return empty or partial content
- llms.txt exists but is malformed — partial parsing with null fields
