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 original URL, a base64-encoded PNG image of the rendered webpage, a unique requestId for tracking, and a capturedAt ISO 8601 timestamp indicating when the screenshot was taken. The image can be decoded and displayed or stored as a PNG file.
Example use cases
Visual website monitoring
“Take a screenshot of https://mycompany.com/pricing every hour and let me know if the layout or content changes — I want to catch any unexpected modifications.”
Competitor page documentation
“Grab a screenshot of https://competitor.io/features so I can see exactly what their features page looks like today and save it for our records.”
Social media preview verification
“Can you screenshot https://myblog.com/new-post so I can check how the page visually renders before I share it on social media?”
Technical details
Endpoint
POSThttps://api.weblens.dev/screenshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a visual, pixel-accurate rendering of a webpage rather than raw HTML or text content. Ideal for visual regression testing, competitive monitoring, social preview checks, or any use case where the rendered appearance of a page matters. The 70% cache discount makes it cost-effective for repeated captures of the same URL.
Side effects
- Invalid or unreachable URL returns an error response
- Timeout if the target page takes too long to load
- Private or authentication-gated pages may render login screens instead of content
- Malformed URL input causes request rejection
- Rate limiting or payment failure via x402 protocol blocks the request
