## 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-fury-boost-d63550ef -d '<json body>'
```

Example prompt: Apply a fury buff to my FortClaw unit with ID 7 to double its damage output.

## When to prefer this

Use this endpoint when you want to increase a specific unit's damage output in FortClaw by 100% of its base power. Prefer this over healing or HP buffs when your strategy requires maximizing offensive capability. Note the 3-fury-per-spawn-cycle cap — check stack count before calling repeatedly.

## Known failure modes

- Unit ID not found or invalid — success: false with error in result
- Fury application limit reached — unit already has 3 fury stacks for this spawn cycle
- Payment failure — x402 payment not completed or insufficient USDC balance
- Missing required unit_id parameter — request rejected
- Invalid wallet address format — authentication fails
