## 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 oblique-markets-web-extraction-sample-purchase-684108a3 -d '<json body>'
```

Example prompt: Can you extract the machine-readable content from https://example.com/products/widget-123 and give me the structured data from that page?

## When to prefer this

Choose this endpoint when you need a single-page, pay-per-use web extraction without committing to a subscription scraping service. Ideal for agents that occasionally need structured data from specific HTTPS URLs and can pay $0.01 USDC per call via x402. Prefer this over full-site crawlers when only one page is needed, and over free scrapers when reliability and machine-readable output formatting matter.

## Known failure modes

- Non-HTTPS URLs rejected — only HTTPS pages are supported
- Payment failure if x402 USDC balance is insufficient or wallet not configured
- Target page returns 4xx/5xx — extraction fails with upstream error
- Paywalled or login-required pages may return incomplete or empty extractions
- Rate limiting or bot-detection on the target site may yield partial data
- Invalid or unreachable URL returns an error response
