# text-chunker-watch

> text-chunker-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 webpage's RAG text chunks for changes, returning current chunks, a changed flag, field-level diffs with before/after values, and last-seen timestamp.

## Facts

- Endpoint: GET https://intel.rallylive.ca/watch/page/chunks
- Price: $0.02/call

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 text-chunker-watch-bbed142c
```

Example prompt: Keep an eye on https://docs.example.com/overview for me — call it on a schedule and let me know whenever the text chunks that would be used for RAG retrieval have changed compared to last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes specifically at the RAG text-chunk level for a given URL, and you want structured before/after diffs rather than a raw page diff. Ideal for automating RAG pipeline re-indexing workflows or tracking knowledge base drift on a schedule. Prefer this over generic page diff tools when you care specifically about how chunked text for LLM retrieval has changed, not just HTML or metadata changes.

## Known failure modes

- URL is unreachable or returns a non-200 status — check may fail or return an error state
- No previous result stored (first call) — 'changed' may default to false or null with no diff available
- URL content is dynamically rendered (JavaScript-heavy) — chunks may not reflect full page content
- Result older than 90 days — previous snapshot is purged, resetting the comparison baseline
- Rate or payment failure — call rejected if $0.02 USDC x402 payment not included

## How this service works

Change watch for text chunker: runs the check and compares it with the result from your previous call for the same url (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 page to rag chunks changes. $0.01 per check.

## Output

Returns the current text chunks extracted from the page, a boolean 'changed' field indicating whether chunks differ from the previous call for the same URL, a detailed diff showing exactly which fields changed with before/after values, and a timestamp of when the page was last seen. Previous results are retained for 90 days for comparison.
