## 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-gateway-production-up-railway-app-5f32694c
```

Example prompt: Take a full-page screenshot of https://example.com and give me the base64 image so I can review what it looks like right now.

## When to prefer this

Use this endpoint when you need a visual snapshot of a live webpage rendered as an image, especially when a base64-encoded output is required for downstream processing. Prefer this over HTML scraping when the goal is visual verification or archival rather than structured data extraction.

## Known failure modes

- URL is unreachable or returns an error (timeout or 4xx/5xx)
- Invalid or malformed URL input
- Page requires JavaScript-heavy rendering that times out
- Access blocked by target site (bot detection, CAPTCHA)
- Payment not completed or insufficient USDC balance

## How this service works

Capture a screenshot of any URL — returns base64-encoded image, supports full-page capture
