## 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 x402-server-send-native-450209d0
```

Example prompt: Use the x402 pay-per-call API to send a native transaction — it costs $0.05 USDC per call and should return a status confirmation when done.

## When to prefer this

Choose this endpoint when you need to send a native blockchain transaction via a simple REST API and are comfortable with the x402 micropayment model ($0.05 USDC per call). It is ideal for agents operating in Coinbase-curated x402 ecosystems where pay-per-call billing is already set up, and when you want a minimal-overhead native send without running your own node infrastructure.

## Known failure modes

- Payment not included or invalid x402 payment header — server returns HTTP 402 Payment Required
- Malformed or missing required input properties — server returns 4xx error
- Vercel cold-start or server unavailability — request times out or returns 5xx
- Insufficient USDC balance to cover $0.05 per-call fee — payment rejected
- Network congestion causing delayed blockchain confirmation
