## 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 yieldprobe-usd-stablecoin-depeg-monitor-bcfdd947 -d '<json body>'
```

Example prompt: Check which USD stablecoins are currently depegged and show me their price deviation from $1 plus how their supply has changed over the last day and 7 days.

## When to prefer this

Choose this endpoint when you need real-time stablecoin peg health data — particularly to detect depeg events, monitor supply trends, or assess stablecoin risk — without building your own price feed aggregation. It is purpose-built for DeFi agent workflows that need both depeg detection and supply change signals in a single call at very low cost.

## Known failure modes

- Payment failure if x402 USDC payment of $0.002 is not fulfilled
- Stale data if on-chain price feeds are temporarily unavailable
- Empty depeg list if all monitored stablecoins are currently on-peg
- Rate limiting or access denial if payment protocol misconfigured

## How this service works

Every depegged USD stablecoin plus the largest by supply, with price deviation and 1d/7d supply change. $0.002 per call.

## Output

A list of USD stablecoins that are currently depegged plus the largest stablecoins by supply, each with: current price, deviation from the $1 peg, a depeg flag, and percentage supply changes over the past 1 day and 7 days.
