## 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 weblens-screenshot-api-b7499d16 -d '<json body>'
```

Example prompt: Can you take a screenshot of https://stripe.com and show me what it looks like right now?

## When to prefer this

Choose this endpoint when you need a visual, pixel-accurate rendering of a webpage rather than raw HTML or text content. Ideal for visual regression testing, competitive monitoring, social preview checks, or any use case where the rendered appearance of a page matters. The 70% cache discount makes it cost-effective for repeated captures of the same URL.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Timeout if the target page takes too long to load
- Private or authentication-gated pages may render login screens instead of content
- Malformed URL input causes request rejection
- Rate limiting or payment failure via x402 protocol blocks the request

## How this service works

# WebLens - Web Intelligence API, pay per call

Scrape, crawl, map and extract the web. No account, no API key, no monthly
minimum — you pay for the calls you make and nothing else.

## Pricing
Page fetching starts at **$0.002**, whole-site crawling at
**$0.0015/page**, and sitemap discovery at **$0.004**.
Comparable services bill $0.007-0.008 per request, or reach a lower per-page
rate only on a $99/month commitment. WebLens has no commitment to reach.

## Payment Protocol
All paid endpoints use the [x402 protocol](https://x402.org) for HTTP-native
micropayments (USDC on Base).

## Cache Discount
Cached responses are **70% cheaper** than fresh fetches.

## Output

A JSON object containing the original URL, a base64-encoded PNG image of the rendered webpage, a unique requestId for tracking, and a capturedAt ISO 8601 timestamp indicating when the screenshot was taken. The image can be decoded and displayed or stored as a PNG file.
