# llms-txt-fetch-watch

> llms-txt-fetch-watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors a site's llms.txt file for changes, returning the current content, a changed flag, field-level diffs with before/after values, and the last-seen timestamp.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability llms-txt-fetch-watch-0e9322b1
```

Example prompt: Keep an eye on openai.com's llms.txt for me — let me know if anything has changed since the last time you checked, and show me exactly which fields are different.

## When to prefer this

Use this endpoint when you need scheduled or on-demand change detection for a site's llms.txt file specifically, with field-level diffs and 90-day history retention. Prefer it over a generic HTTP fetch when you need to know *what* changed (not just *that* something changed), and when you want to automate alerts tied to AI directive modifications across domains.

## Known failure modes

- Domain has no llms.txt file — returns an error or empty result
- First call for a domain has no previous result to compare against — changed flag may be undefined or false
- Domain is unreachable or returns a non-200 HTTP status — fetch fails
- Previous result expired after 90 days — treated as a fresh first-time check
- Malformed llms.txt content may cause incomplete field parsing

## How this service works

Change watch for llms txt fetch: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when llms changes. $0.01 per check.

## Output

Returns the current llms.txt content for the domain, a boolean indicating whether it changed since the previous call, a list of fields that changed with before and after values, and the timestamp of when the content was last seen. Previous results are retained for 90 days for comparison.
