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: a synthesized natural-language answer to the query, an array of citations (each with URL, title, and index number), a confidence score (0–1), a unique request ID, and a timestamp of when the answer was generated.

When to prefer

Choose this endpoint when you need a direct, cited natural-language answer to a factual question rather than raw scraped HTML or a list of search results. It is best for research, fact-checking, and knowledge retrieval tasks where the agent needs a synthesized conclusion backed by verifiable web sources. Prefer it over raw scraping endpoints when interpretability and citation quality matter more than raw content access.

Side effects

Query too vague or ambiguous — low-confidence answer returned
Topic has no recent web coverage — citations may be sparse or stale
Payment failure via x402 — HTTP 402 returned if payment not authorized
Rate limiting or abuse detection — HTTP 429 returned
Internal search or synthesis error — HTTP 500 with error message
