## 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-add-pool-12b88f85
```

Example prompt: Add a new pool to the x402 agent server — use the required properties I've set up and pay the $3 USDC fee via x402 to register it.

## When to prefer this

Choose this endpoint when you need to programmatically create or register a new pool on an x402-protocol-enabled server and are prepared to pay $3 USDC per call. Best suited for agents that manage x402 infrastructure or automate DeFi/resource pool provisioning workflows where micropayment-gated API access is acceptable.

## Known failure modes

- Payment not included or insufficient USDC (402 Payment Required)
- Missing required fields in request body (400 Bad Request)
- Pool already exists or conflict (409 Conflict)
- Server unavailable or cold-start timeout on Vercel (503/504)
- Malformed properties object causing parsing error (422 Unprocessable Entity)
