Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-research-api-f8fa2b37 -d '<json body>'
```

Example prompt: Can you research the benefits and tradeoffs of the x402 payment protocol for me — pull from real web sources and give me a summary with key findings?

## When to prefer this

Choose this endpoint when you need synthesized, multi-source web research rather than a raw page scrape. It is ideal when the user wants a summary with cited sources rather than raw HTML or a single page's content. Prefer it over single-URL fetch endpoints when the query spans multiple web sources. The $0.08 price point (or ~$0.024 for cached) makes it cost-effective for moderate research workloads where fresh intelligence matters.

## Known failure modes

- Query too vague or empty — returns validation error
- Payment not provided or insufficient — returns HTTP 402 with x402 payment details
- Rate limiting if too many requests in a short period
- Web sources unavailable or blocked — may return partial results
- Cached response served when fresh data expected — use cache-bypass option if available

## 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 containing: the original query, an array of sources (each with URL, title, and snippet), an AI-generated prose summary, a list of key findings as bullet points, a unique requestId, and a timestamp of when the research was performed.
