How this service works
Screenshot any URL. Extract structured data. Monitor for changes. Developer API with pay-per-call pricing — no API keys, no accounts.
Output
Returns a JSON object containing the requested task type, a result object with task-specific fields (e.g. category, tags, and confidence score for classification), and payment metadata including the payer address and price in USDC units. Latency in milliseconds is also included.
Example use cases
Automated landing page categorization
“Go to https://acme.com and classify it — I want to know what category it falls under and any relevant tags, like whether it's a landing page, blog, or e-commerce site.”
Entity extraction from competitor pages
“Extract all named entities from https://competitor.com/about — things like people, organizations, products, and locations mentioned on the page.”
Sentiment check on product review page
“Analyze the sentiment of https://reviews.example.com/product/123 — is the overall tone of the page positive, negative, or neutral?”
Technical details
Endpoint
GEThttps://webcap.shoutsid.fyi/v1/x402/analyze?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, task-specific analysis of a live webpage — especially classification, entity extraction, accessibility auditing, sentiment scoring, or layout analysis — without managing API keys or accounts. It is well-suited for pay-per-call agent workflows using x402 micropayments at $0.01 per call. Prefer this over general LLM web browsing when you need a consistent structured JSON output with confidence scores rather than a free-form summary.
Side effects
- Invalid or unreachable URL returns an error — ensure the URL is publicly accessible
- Unsupported task enum value returns a validation error
- Page behind authentication or bot protection may return incomplete or blocked results
- Slow-loading pages may timeout or return degraded results
- Ambiguous context string may reduce accuracy of the analysis result
