## 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 gedx402-browser-screenshot-b2215dd4
```

Example prompt: Take a full-page screenshot of https://example.com and give me back the image — I want to see exactly what the page looks like right now.

## When to prefer this

Use this endpoint when you need a visual screenshot of any public URL or rendered HTML and want to pay per-call in USDC without managing API keys or subscriptions. Prefer it over browser automation SDKs when you need a lightweight, pay-as-you-go screenshot API. It's ideal for AI agents that need visual context about a webpage, thumbnail generation, or visual QA — especially when operating in crypto-native or keyless environments.

## Known failure modes

- Invalid or unreachable URL returns an error or blank image
- Timeout if the page takes too long to load (gotoOptions.waitUntil can help)
- JavaScript-heavy SPAs may not render fully without waitUntil: networkidle0
- Invalid viewport or screenshotOptions cause parameter validation errors
- Payment failure (insufficient USDC balance or unsupported chain) results in HTTP 402 with no image returned
- Raw HTML that references external resources may not load them fully in the sandbox

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

## Output
