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 an array of crawled pages, each with its URL, depth, title, HTTP status, and full markdown content (with a truncation flag). Also includes a summary with counts of crawled, successful, failed, and discovered pages, max depth reached, robots.txt compliance status, the timestamp, and a request ID.
Example use cases
Documentation site indexing for RAG
“Crawl all the pages on docs.stripe.com up to 2 levels deep — I want the full markdown content of each page so I can load it into a vector database for a support chatbot.”
Competitor website content audit
“Go through the entire marketing site at competitor.com, up to 3 levels deep and no more than 100 pages, and pull back the text content of every page so I can analyze what topics they cover.”
Internal wiki knowledge extraction
“Crawl our company wiki at wiki.internal.io starting from the homepage, up to 4 levels deep, and get me the title and full content of every page you find.”
Technical details
Endpoint
POSThttps://api.weblens.dev/crawl?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to retrieve content from multiple pages across an entire site rather than a single URL. It is ideal for building knowledge bases, indexing documentation, auditing site content, or feeding website text into downstream AI pipelines. Prefer it over single-page fetch endpoints whenever you need breadth across a domain. The pay-per-call model (no monthly commitment) makes it cost-effective for sporadic or one-off full-site crawls compared to subscription-based alternatives.
Side effects
- Target site blocks crawlers or returns 403/429 — affected pages will have status 'failed' in the response
- Robots.txt exclusions prevent crawling certain paths when robotsRespected is true
- Very large sites may hit the page limit before full discovery
- Network timeouts on slow or unreliable target servers
- Invalid or unreachable starting URL returns an error response
- JavaScript-rendered pages may not return full content if the site requires a browser runtime
