## 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-content-fetch-api-9632f572 -d '<json body>'
```

Example prompt: Can you fetch the full text content from https://techcrunch.com/2024/01/15/openai-raises-funding/ and return it as clean readable text?

## When to prefer this

Choose this endpoint when you need to fetch and read raw web page content from arbitrary URLs without setting up a browser environment. It is especially useful for AI agents that need to ingest, summarize, or analyze content from specific web pages, and offers a cache discount (70% cheaper) when the same URL has been recently fetched by another user.

## Known failure modes

- URL is unreachable or returns HTTP error — status field will reflect failure
- Page requires JavaScript rendering and content is not available in static HTML
- Website blocks scraping via robots.txt or anti-bot measures — returns failed status
- URL is malformed or missing — request validation error
- Rate limiting or server timeout on the target domain

## 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

Returns a JSON object with a results array where each entry contains the URL, title, full extracted content as markdown, success status, and a truncated flag. Also includes a summary with total/successful/failed counts, a fetchedAt timestamp, and a unique requestId.
