## 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-and-depeg-monitor-405d380f
```

Example prompt: Can you check the current peg status of all the major stablecoins — USDT, USDC, DAI, USDe — and let me know if any of them are depegged or showing a warning?

## When to prefer this

Choose this endpoint when you need a fast, aggregated, multi-source peg health check across all major stablecoins in a single call, combining both DEX market depth and Chainlink oracle data — rather than querying individual price feeds or building your own aggregation. Ideal for pre-trade safety checks, DeFi risk monitoring, and automated stablecoin health dashboards.

## Known failure modes

- Payment failure if x402 USDC micropayment of $0.005 is not included or rejected
- Stale data if DEX or Chainlink oracle feeds are temporarily unavailable
- Thin market flag if a stablecoin has insufficient DEX liquidity to assess peg accurately
- Network timeout if the upstream DEX or oracle data source is slow to respond

## How this service works

Stablecoin peg and depeg monitor ($0.005): is USDT, USDC, DAI, USDS, USDe, PYUSD, GHO, crvUSD, RLUSD, USD1 or FDUSD still worth a dollar? DEX price, depth of a $100k sale and Chainlink price, status PEGGED, WATCH, DEPEG or THIN_MARKET, refreshed every 5 minutes.

## Output

Returns peg status (PEGGED, WATCH, DEPEG, or THIN_MARKET) for each covered stablecoin (USDT, USDC, DAI, USDS, USDe, PYUSD, GHO, crvUSD, RLUSD, USD1, FDUSD), along with the current DEX spot price, Chainlink oracle price, and estimated market impact depth of a $100,000 sell order, refreshed every 5 minutes.
