## 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 defi-slippage-check-467e844e -d '<json body>'
```

Example prompt: Before I execute this swap, check if a slippage tolerance of 150 basis points is safe — the token is high volatility.

## When to prefer this

Use this endpoint when you need a fast, pre-trade check on whether a configured slippage tolerance is safe given a token's volatility profile, especially before submitting automated swaps where sandwich-attack exposure or excessive slippage is a concern.

## Known failure modes

- Missing required slippageBps field returns validation error
- Invalid or out-of-range basis point value may return an error or unexpected result
- Unknown tokenVolatility string value may be ignored or cause a bad request
- Payment failure (402) if x402 payment header is missing or insufficient
- Service unavailability on Railway hosting platform
