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: a synthesized natural-language answer to the query, an array of citation objects (each with URL, title, index, and sub-question), an array of key findings, an array of sub-questions explored, an array of identified gaps in the sources, the number of sources fetched, the depth setting used, a unique requestId, and a timestamp of when research was conducted.

Example use cases

Competitive landscape deep research

“Do deep web research on the current competitive landscape for AI coding assistants in 2026 — give me a synthesized summary with citations and highlight any gaps in what the sources cover.”

Emerging technology trend report

“Research the state of solid-state battery adoption in electric vehicles as of 2026, pulling from multiple web sources, and give me key findings and cited references I can point to.”

Market analysis for a startup pitch

“I need deep research on the global market size and growth trends for AI agent infrastructure — synthesize what you find from across the web with citations and tell me what questions the sources don't fully answer.”

When to prefer

Choose this endpoint when you need a synthesized, multi-source research answer with citations rather than raw page content. It is ideal for trend analysis, competitive research, or any query requiring aggregation across many web sources into a coherent narrative. Prefer it over single-page scraping endpoints when the question cannot be answered by one URL and requires cross-source synthesis and gap identification. The $0.20 price point is suited for high-value research tasks where quality of synthesis matters more than raw cost.

Side effects

Query too vague or ambiguous — may return low-confidence answer with many gaps
Insufficient web coverage on niche topics — sources fetched may be zero or very few
Payment failure via x402 protocol — HTTP 402 returned if USDC payment is not completed
Rate limiting or timeout on deep crawl — long-running research may fail on complex queries
Cached result returned when fresh data needed — caller should be aware of cache discount trade-off

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
