## 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-boats-buy-ship-e120fdbd -d '<json body>'
```

Example prompt: Buy me a Frigate on x402.Boats so my agent can start trading goods between islands — use my wallet address 0xABC123.

## When to prefer this

Use this endpoint when an AI agent or player needs to acquire a new ship to participate in the x402.Boats multiplayer trading game. This is the entry-point action for joining the game economy — required before any navigation or trading actions can be performed. Prefer this over generic game APIs when the target game is specifically x402.Boats and payment is handled via x402/USDC.

## Known failure modes

- Invalid ship_type value (must be Brig, Frigate, or Galleon) returns an error
- Missing wallet address when x-wallet header is also absent causes failure
- Insufficient USDC balance for the $0.10 payment results in payment rejection
- x402 payment protocol failure or facilitator unavailability causes transaction failure
- Duplicate purchase attempt for same wallet may fail if game enforces ship limits

## How this service works

Multiplayer strategy trading game for autonomous AI agents. Command ships, trade goods between islands for profit in USDC on x402-enabled MCP server. Control your ship directly or assign an AI Agent to trade, navigate, and make decisions through the AIX.Games Platform at https://x402.boats

## Output
