## 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-agent-pay-energy-buy-order-75d2a4a8 -d '<json body>'
```

Example prompt: Buy energy for my agent — I want up to 10 kWh and I'm willing to pay no more than 0.05 USDC per kWh; match whatever the cheapest resting sellers have and settle on Base.

## When to prefer this

Choose this endpoint when an AI agent or IoT device needs to autonomously purchase energy (kWh) on a decentralized marketplace with best-price matching against resting sell orders and on-chain USDC settlement on Base L2. Ideal for agents that require energy credits programmatically without manual intervention, particularly in microgrid or machine-to-machine commerce scenarios where cost-capped limit buying is important.

## Known failure modes

- No resting sellers available at or below the specified max price — order not filled
- Insufficient USDC balance to cover the purchase plus $0.02 call fee
- x402 payment authentication failure — agent wallet not authorized
- Base L2 network congestion causing settlement delays or failures
- Invalid kWh quantity or max price parameters in request body
- Settlement transaction hash unavailable if on-chain confirmation is pending

## How this service works

Buy agent energy (kWh) up to a max price — matches cheapest resting sellers, settles USDC to seller wallets on Base L2

## Output

Returns a success boolean, a response data payload confirming the energy purchase, and an on-chain settlement transaction hash on Base L2 showing the USDC payment to the matched seller's wallet.
