## 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 coin-railz-instant-agent-wallet-creation-7f8a1c0a -d '<json body>'
```

Example prompt: Set up a new MPC-secured Circle USDC wallet for my AI agent with ID 'agent-trading-bot-001', labeled 'Trading Bot Primary Wallet', and fund it with 10 USDC to start.

## When to prefer this

Use this endpoint when you need to programmatically create a new Circle MPC-secured USDC wallet specifically for an AI agent identity, and want developer-controlled (not user-controlled) wallet infrastructure with instant provisioning. Prefer this over generic wallet APIs when you need Circle's MPC custody model and the x402 micropayment protocol for agent-native crypto infrastructure.

## Known failure modes

- Missing or invalid agentId returns a 400 validation error
- Payment of 1 USDC not fulfilled causes a 402 Payment Required response
- Circle API backend unavailable causes a 503 or timeout
- Duplicate agentId may conflict with an existing wallet depending on service logic
- Invalid initialFundingAmount (e.g. negative) may return a 400 error
