## 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 stablecoin-peg-health-check-370bed84
```

Example prompt: Is USDC currently holding its dollar peg? Give me the exact price deviation in basis points and tell me whether it's at risk of depegging.

## When to prefer this

Use this endpoint when you need a fast, single-call live peg health snapshot for a specific stablecoin — including deviation in basis points and peg mechanism context — especially for depeg alerting, risk dashboards, or DeFi safety checks. Prefer this over general crypto price APIs when you specifically need peg-deviation framing and stablecoin risk metadata.

## Known failure modes

- Unrecognized stablecoin symbol or address returns a 400 or 404 error
- Price feed temporarily unavailable returns a 503 or error response
- Stablecoin not supported by the endpoint returns an error indicating no data
- Network issues or timeout result in no response
