## 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 x402-cloud-browser-act-webpage-interaction-action-execution-757e7e6f -d '<json body>'
```

Example prompt: Go to https://example.com/products, click the 'Add to Cart' button for the first item, then return the page text and a screenshot of the result.

## When to prefer this

Use this endpoint when an AI agent needs to interact with a live webpage through structured browser actions — clicking, typing, navigating — and extract resulting text or screenshots, especially in pay-per-call x402 USDC micro-payment contexts without needing to manage browser infrastructure. Prefer this over static HTML fetchers when the target page is dynamic or requires user interaction before content appears.

## Known failure modes

- Invalid or inaccessible URL returns success:false with errors array populated
- Actions array exceeds 10 items — request rejected by schema validation
- Target page requires authentication and blocks automated access — success:false
- Browser action references element not found on page — partial success with errors
- Network timeout reaching target URL — success:false with timeout error
- Malformed BrowserAction objects in actions array cause validation failure

## Output

A JSON object containing: 'success' (boolean indicating if actions completed), 'final_url' (the URL the browser ended on after all actions), 'text' (extracted text content of the page, or null), 'errors' (array of error message strings if any steps failed), and 'screenshot_url' (URL to a screenshot image if requested, or null).
