# form-detect-watch

> form-detect-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 for changes in form detection results, returning a diff of what changed since the last check.

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 form-detect-watch-65369849
```

Example prompt: Keep an eye on https://example.com/contact and let me know whenever the forms detected on that page change — I want to see exactly which fields appeared or disappeared compared to the last check.

## When to prefer this

Choose this endpoint when you need to be notified of changes in form detection on a specific page over time, rather than just getting a one-time snapshot. It is ideal for scheduled agent workflows that need to track whether forms appear, disappear, or have their fields modified. Prefer this over a single form-detect check when continuity and delta detection matter.

## Known failure modes

- URL is unreachable or returns a non-200 status — check may fail or return no forms detected
- No previous result exists for the URL (first call) — changed flag may be null or false with no diff
- Page requires JavaScript rendering that the crawler doesn't support — forms may not be detected
- Payment not fulfilled — request rejected before check runs
- URL changes redirect target between calls — comparison may reflect redirect destination changes rather than original page

## How this service works

Change watch for form detect: 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 form detection on a page changes. $0.01 per check.

## Output

Returns the current form detection result for the given URL, a boolean indicating whether it changed since the last call, a detailed diff of exactly which fields changed with before and after values, and a timestamp of when it was last seen. Results are retained for 90 days for comparison.
