## 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 stamina-budget-calculator-0b953fa6 -d '<json body>'
```

Example prompt: I have a stamina pool of 150 and each action costs 22 stamina — how many actions can I take before I run out?

## When to prefer this

Use this endpoint when building game tools, RPG utilities, or design calculators that need to quickly compute action counts from stamina resources without implementing the arithmetic manually. Ideal for game designers, tabletop assistants, and agent-driven RPG helpers.

## Known failure modes

- Missing or zero cost_per_action causing division by zero
- Non-numeric values for stamina or cost_per_action fields
- Negative stamina or cost values producing nonsensical results
- Payment failure (402) if USDC balance is insufficient
