## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability webcap-web-analysis-api-page-classification-entity-extraction-5a79822b
```

Example prompt: Can you classify this page for me — https://example.com/pricing — and tell me what category it falls into and how confident you are?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
