## 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-unit-hp-boost-5643e278 -d '<json body>'
```

Example prompt: In FortClaw, apply a molt to unit 42 to give it the +50% HP bonus — I want it tougher before the next battle.

## When to prefer this

Use this endpoint when you want to increase a specific unit's survivability in FortClaw by granting a +50% HP bonus. Prefer this over healing (which restores existing HP) when you want to permanently increase the unit's effective health pool. Best used early in a spawn cycle before the 3-molt cap is reached.

## Known failure modes

- Unit ID not found or invalid — molt fails with success: false
- Max 3 molts per spawn cycle already reached for this unit — operation rejected
- Insufficient USDC balance or payment failure ($5 required) — transaction not processed
- Missing unit_id in request body — validation error
- Wallet address not provided via body or x-wallet header — authorization failure

## How this service works

Give a unit +50% bonus HP from its base value. Max 3 molts per spawn cycle.

## Output
