## 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-pdf-extraction-api-e0eace71 -d '<json body>'
```

Example prompt: Can you extract all the text from this PDF — https://example.com/report.pdf — and tell me the title, author, and what's on each page?

## When to prefer this

Choose this endpoint when you need to programmatically read the contents of a PDF hosted at a public URL, especially when you also need per-page structure and document metadata (title, author, page count). Prefer it over generic web scraping endpoints when the target is specifically a PDF file. The caching discount makes it cost-effective for repeated access to the same document.

## Known failure modes

- URL is not reachable or returns a non-200 status — extraction fails with an error
- URL does not point to a valid PDF — parsing error returned
- PDF is password-protected or DRM-restricted — content cannot be extracted
- Very large PDFs may time out or return partial results
- 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 PDF URL, an array of page objects (each with pageNumber and content), the full concatenated text, document metadata (title, author, page count), a unique request ID, and an ISO timestamp of when the extraction occurred.
