## 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 control-operativo-x402-preflight-herramientas-para-asaderos-735ebd21
```

Example prompt: Before paying for the asadero inventory and sales control templates, can you run a preflight check on the herramientas-cobrables endpoint to find out the exact USDC amount, the wallet address to pay, and which network (eip155) to use?

## When to prefer this

Use this endpoint as the mandatory first step before making any paid call to the herramientas-cobrables asadero tools API, specifically when you need to discover or confirm x402 payment parameters (payTo address, USDC amount, network) programmatically before authorizing a blockchain micropayment on Base or another eip155 network.

## Known failure modes

- Invalid or missing URL query parameter returns a validation error
- Mismatched expected_network or expected_amount_usd causes a preflight mismatch response
- Network or RPC connectivity issues may return a timeout or 5xx error
- Malformed eip155 chain ID pattern causes schema validation failure
- Target endpoint unavailable results in an unreachable error
