## 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 fortclaw-molt-pack-purchase-f87905b3 -d '<json body>'
```

Example prompt: Buy me a Molt Pack in FortClaw using my wallet address 0xABC123 so I get a random unit spawned at Zone 0.

## When to prefer this

Use this endpoint when an agent wants to acquire a new unit to participate in the FortClaw territory game. This is the entry-point action for gaining units — all other FortClaw actions (teleport, heal, fury, molt, bomb, nuke) require an existing unit obtained through this pack purchase.

## Known failure modes

- Insufficient USDC balance — payment of $25 fails, returns success: false
- Invalid or missing wallet address — cannot attribute the unit to a wallet
- x402 payment protocol error — payment header not properly formed
- Unit assignment failure — random unit generation or spawn fails server-side

## How this service works

## Output

Returns a success boolean and a result object confirming the pack purchase, with a randomly assigned unit now spawned at Zone 0 on the FortClaw map.
