## 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 conway-replicatio-mg-web-ground-extract-b36d2c73 -d '<json body>'
```

Example prompt: Can you extract the main content from https://example.com/article using the mg-web-ground-extract tool and give me what it finds?

## When to prefer this

Use this endpoint when you need to extract structured ground-truth content from a single, publicly accessible URL and are operating in a pay-per-call agent workflow settling in USDC on Base via x402. It is well-suited for agentic pipelines that need to fetch and parse web content on demand without maintaining a scraping infrastructure.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — extraction fails
- URL points to a paywalled or bot-blocked resource — empty or error data returned
- Invalid URI format in the 'url' field — schema validation error
- Target page returns non-HTML or binary content — unparseable result
- Network timeout or Cloudflare Worker failure — service unavailable error

## How this service works

Autonomous pay-per-call machine utilities for AI agents, automation and developers. Payments settle in USDC on Base through x402.

## Output

Returns a JSON object with an 'ok' boolean, a 'data' object containing the extracted content from the target URL, and a 'capability' field confirming 'mg-web-ground-extract'. The data field holds the parsed/extracted ground-truth content from the provided web page.
