## 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 manylives-trading-risk-calculator-ea5154d0
```

Example prompt: I have a $10,000 trading account and want to risk 1% on a long Bitcoin trade — entry at $120,000, stop at $117,600, target at $124,800, with 10x leverage. Can you calculate my position size, liquidation price, and reward-to-risk ratio?

## When to prefer this

Use this endpoint when an AI trading agent needs to compute exact position sizing and risk metrics before placing a trade, especially for leveraged crypto or futures positions where liquidation price and margin requirements are critical. Prefer this over manual calculation when you need break-even win rate and fee-adjusted risk in a single call. It requires no account registration and charges only $0.005 USDC per call via x402.

## Known failure modes

- Missing required parameters (account, risk_pct, entry, stop) return an error
- Stop price equal to or above entry for a long trade may produce nonsensical results
- Leverage outside 1-125 range may be rejected
- Non-numeric string values for price/account fields cause parsing errors
- Payment of 0.005 USDC not fulfilled results in HTTP 402 response
