## 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 market-memoryapi-org-bb20c40e
```

Example prompt: Check all the major stablecoins right now and tell me which ones are deviating from their $1.00 peg — I want to know the percentage off and which direction.

## When to prefer this

Use this endpoint when you need real-time peg stability data specifically for stablecoins and want a simple depeg deviation metric. Prefer this over general crypto price endpoints when the focus is risk monitoring, DeFi safety checks, or detecting depegging events across multiple stablecoins at once.

## Known failure modes

- Price feed unavailable — upstream data source timeout
- Stablecoin not tracked — unknown or unlisted asset returns empty result
- Rate limit exceeded — too many requests in short window
- Payment verification failure — x402 payment header invalid or insufficient
