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 aayat-ai-page-changes-summary-2907d2fd -d '<json body>'
```

Example prompt: Check https://example.com/pricing for any changes since last time — here's the token from my previous check: fZDNasMwEIRf... — and give me a summary of what was added or removed.

## When to prefer this

Choose this endpoint when you need lightweight, stateful, pay-per-call webpage change monitoring without setting up any account or infrastructure. It is ideal for agents that periodically poll URLs and need a concise natural-language summary of what changed rather than raw HTML diffs. Prefer it over full-page scraping tools when you only care about textual content changes and want the token-based continuity to avoid re-processing unchanged content. The ignoreNumbers flag makes it especially useful when pages have frequently updating counters or timestamps that would otherwise create noise.

## Known failure modes

- Invalid or unreachable URL returns an error with no diff data
- Expired or corrupted token causes the endpoint to treat the request as a first check, losing change history
- Page behind authentication or bot-detection may return empty or incorrect content
- Very large pages may hit the token size limit (60,000 characters)
- If the page structure changes drastically, the diff may produce noisy or misleading added/removed entries

## How this service works

Page change detection with an AI summary: like /page/changes (send back the token from your last check), plus a two-sentence summary of what changed and whether it looks significant (price, policy, product or content change) versus noise. POST {url, token}.

## Output

A JSON object containing: a boolean indicating whether the page changed, a human-readable summary of what changed, arrays of added and removed text snippets, the page title, a content hash, timestamps of the current and previous check, block count, and a token to pass on the next call to enable incremental diffing.
