## 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 button-labels-joined-text-extraction-b54c1c8c -d '<json body>'
```

Example prompt: Can you extract and join all the button labels from this page https://example.com/product where the button has id 'submit' and I'm looking for buttons related to 'checkout'? I've already seen 'Add to Cart' so skip that one.

## When to prefer this

Choose this endpoint when you need to quickly extract and join visible text from button elements on a static public webpage or a known HTML snippet without JavaScript rendering. It is ideal for UI audits, CTA copy analysis, competitive research on button labels, or monitoring changes in button text over time. Prefer this over general-purpose scrapers when you specifically need button label data with attribute-level filtering and deduplication against previously seen texts.
