## 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-batch-fetch-api-bed2e7a1 -d '<json body>'
```

Example prompt: Can you fetch and extract the content from these three URLs all at once: https://example.com/article1, https://example.com/article2, and https://example.com/article3? I need the full page text from each.

## When to prefer this

Choose this endpoint when you need to scrape or extract content from multiple URLs in a single API call rather than making individual fetch requests. It is more efficient than calling a single-URL endpoint repeatedly, and the $0.006 flat rate per batch call (with 70% discount for cached responses) makes it cost-effective for bulk research, competitive analysis, or content aggregation workflows.

## Known failure modes

- Individual URLs in the batch may fail (status: failed) while others succeed — partial success is possible
- Payment failure via x402 protocol if insufficient USDC balance
- Rate limiting or timeout on very large batches
- URLs behind authentication walls or bot-detection may return incomplete or blocked content
- Invalid or malformed URLs in the batch will result in failed status for those entries

## 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, page title, content text, and status (success or failure). Also includes a summary with total/successful/failed counts, a requestId for tracking, and the totalPrice charged for the batch.
