# Extract Inline Code as JSON - Change Watch

> Extract Inline Code as JSON - Change Watch is a paid API for AI agents from page.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-20).

Monitors a webpage's inline code blocks for changes, returning current extracted JSON, a changed flag, before/after diffs, and 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 extract-inline-code-as-json-change-watch-1e501166
```

Example prompt: Keep an eye on this page and tell me if any of its inline code blocks have changed since the last time you checked — show me exactly what changed and what the old versus new values were.

## When to prefer this

Choose this endpoint when you need to detect changes to inline code blocks specifically (not full page text, tables, or meta tags) and require a structured diff with before/after field values. It is especially useful for scheduled monitoring workflows where you want to be alerted only when something actually changes, rather than re-parsing the entire page yourself. Prefer sibling watch endpoints for other element types like tables, buttons, or meta tags.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails
- No inline code elements found on the page — returns empty result
- First-time call for a URL has no previous result to compare against — changed flag may be indeterminate
- Previous result expired (older than 90 days) — baseline lost, treated as first call
- Payment not processed — request blocked at x402 paywall

## How this service works

Change watch for extract inline code as json: runs the check, compares it with the result from your previous call for the same url (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the currently extracted inline code as JSON, a boolean 'changed' flag indicating whether it differs from the previous check (stored for 90 days), a list of fields that changed with their before and after values, and the timestamp of when the page was last seen.
