How this service works
Read a website's /llms.txt (the standard that tells LLMs what a site is about) as structured data: title, summary, sections with links and descriptions, and whether llms-full.txt exists.
Output
Returns a JSON object with: the site URL, raw llms.txt text, parsed title, summary/description, an array of sections each containing a title and an array of links (each with URL, anchor text, and description), total character count, total link count, and a boolean indicating whether llms-full.txt is available.
Example use cases
AI agent onboarding to new site
“Before I start using docs.example.com, can you read its llms.txt and give me a structured summary of what the site covers — title, overview, and all the main sections with links?”
Checking LLM discoverability of a domain
“Does openai.com have a proper llms.txt? If so, pull it and tell me the title, summary, whether llms-full.txt exists, and how many links are listed across all sections.”
Aggregating site descriptions for a directory
“I'm building a directory of AI-friendly sites — can you read the llms.txt at huggingface.co and return the structured data including title, summary, and all section titles with their links and descriptions?”
Technical details
Endpoint
POSThttps://api.vextorium.com/leer-llms-txt-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically understand what a website wants LLMs to know about it, without scraping the full site. Ideal for agents building site summaries, checking AI discoverability, or ingesting structured llms.txt metadata. Better than raw scraping for this specific use case since it handles the llms.txt standard parsing and normalization for you.
Side effects
- Site does not have a /llms.txt file — returns null fields or an error
- URL is malformed or unreachable — network or parse error returned
- llms.txt exists but does not conform to the standard format — partial or empty parsed fields
- Payment not sent — HTTP 402 returned before data is delivered
