## 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 mike-digital-arbitrage-agent-api-extract-1df18b94 -d '<json body>'
```

Example prompt: Extract structured product pricing data from https://example.com/product/123 and return it as JSON with fields for name, price, and availability.

## When to prefer this

Choose this endpoint when you need to extract structured or semi-structured data from a specific URL with minimal setup, especially for digital arbitrage use cases like price monitoring, deal comparison, or content harvesting. Prefer it over generic scrapers when you want to optionally supply a target schema to shape the output. It is well-suited for one-shot extractions from live web pages rather than full-site crawls.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — extraction fails with an error
- URL points to a JavaScript-heavy SPA that requires rendering — content may be incomplete or missing
- Provided schema does not match available content — returned fields may be null or empty
- ngrok tunnel is offline or expired — endpoint returns connection refused or 502
- Rate limiting or bot-protection on the target site blocks the request
- Malformed URL input returns a 400 validation error

## How this service works

ngrok is the fastest way to put anything on the internet with a single command.

## Output
