## 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 screenshot-x402-analyze-screenshot-3cad7576 -d '<json body>'
```

Example prompt: Screenshot the page at https://example.com at 1280x800 in dark mode and describe what you see in three short sentences — hide the cookie banner using '#cookie-notice' before capturing.

## When to prefer this

Choose this endpoint when you need both a visual capture of a webpage AND an immediate AI-generated textual interpretation of that capture in a single pay-per-request call with no API key setup. Ideal for agents that need to understand what a page looks like without storing or processing raw image bytes themselves. Prefer over plain screenshot endpoints when the downstream task requires natural language understanding of page content.

## Known failure modes

- Invalid or unreachable URL returns an error with no screenshot
- Vision model fails to process image, returning empty content array
- Viewport dimensions out of allowed range (100–3840 x 100–2160) cause validation error
- CSS selectors list exceeds 40 items, triggering schema validation failure
- Payment not completed via x402 protocol results in 402 Payment Required response
- Page takes too long to render, causing timeout with no result
