## 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 tollkit-extract-17cba731 -d '<json body>'
```

Example prompt: Can you extract the product details from this page for me — pull everything structured from it and pay for it on-chain?

## When to prefer this

Choose Tollkit Extract when you need pay-as-you-go product page extraction with zero onboarding — no account creation, no API key provisioning, just an in-band USDC micropayment via x402 on Base or Solana. Ideal for agents that need occasional or unpredictable extraction volume and want to avoid subscription commitments.

## Known failure modes

- Insufficient USDC balance or failed x402 payment results in 402 Payment Required response
- Invalid or inaccessible URL returns an extraction error
- Page is behind a login wall or anti-bot protection causing incomplete extraction
- Malformed input parameters (e.g. invalid date format or currency code) result in 400 Bad Request
- Network timeout if target page is slow to respond
