## 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 convert-webpage-to-markdown-change-watch-d5f5ed3a
```

Example prompt: Keep an eye on that webpage for me — call the convert-webpage-to-markdown watch check so I know exactly what changed in the markdown output since the last time we looked.

## When to prefer this

Choose this endpoint when you need scheduled monitoring of a webpage's markdown content and want structured diff output (before/after per field) rather than just a raw conversion. Ideal for agents that poll on a schedule and need to act only when content changes, rather than processing every response unconditionally.

## Known failure modes

- No previous result stored (first call returns changed=false or null baseline)
- URL is unreachable or returns a non-200 status, causing the check to fail
- 90-day history window exceeded, losing the comparison baseline
- Malformed input object missing required 'type' or 'method' fields
- Payment failure preventing the $0.02 USDC charge from completing

## How this service works

Change watch for convert webpage to markdown: 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 convert webpage to markdown changes. $0.02 per check.

## Output

Returns the current markdown conversion result, a boolean 'changed' flag indicating whether the output differs from the previous call for the same URL (stored up to 90 days), a list of exactly which fields changed with before and after values, and a timestamp of when the result was last seen.
