How this service works
llms.txt reader: checks whether a site publishes llms.txt or llms-full.txt (the emerging standard for telling AI agents what a site offers), returns the content (up to 20 KB) and its headings and links. Discover agent-friendly documentation instantly. $0.01 per domain.
Output
Returns whether llms.txt or llms-full.txt exists at the given domain, up to 20 KB of file content, a list of parsed headings, and all links found within the file — enabling agents to quickly understand what a site intentionally exposes to AI consumers.
Example use cases
Vetting AI-friendly API providers
“Before I integrate with openai.com, can you fetch their llms.txt file and tell me what sections and links it lists so I know what they expose to AI agents?”
Building an agent tool directory
“I'm compiling a list of developer tools that support the llms.txt standard — can you check whether vercel.com, supabase.com, and anthropic.com each have an llms.txt or llms-full.txt and what headings they contain?”
Debugging missing agent documentation
“My AI agent can't find documentation for the Resend API — can you check resend.com for an llms.txt or llms-full.txt file and return whatever content and links are there?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/site/llms-txtWhen to prefer
Use this endpoint when you need to quickly discover whether a website intentionally documents itself for AI agents via the llms.txt standard. It is the right choice when building agent tool directories, auditing AI-readiness of APIs, or pre-checking a domain before deeper crawling. Prefer it over general web scraping when you specifically want the structured llms.txt signal rather than raw HTML.
Side effects
- Domain does not publish llms.txt or llms-full.txt — returns empty or not-found result
- Domain unreachable or returns non-200 status — network/HTTP error
- File exceeds 20 KB cap — content is truncated
- Malformed llms.txt with no parseable headings or links — empty structured fields
- Invalid or non-existent domain name — DNS resolution failure
