## 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-supply-by-chain-peg-price-and-depeg-monitor-15c69070 -d '<json body>'
```

Example prompt: Can you pull up the current peg price and chain-by-chain supply breakdown for USDT, and let me know if it's showing any depeg?

## When to prefer this

Use this endpoint when you need a combined view of a stablecoin's cross-chain supply distribution, real-time peg price, and depeg status in a single call. Prefer this over generic crypto price endpoints when you specifically need stablecoin-focused data including chain-level supply breakdown and depeg monitoring for major stablecoins like USDC, USDT, PYUSD, or USDe.

## Known failure modes

- Unknown or unsupported stablecoin symbol returns an error or empty result
- Data may lag real-time market conditions by minutes
- Very new or obscure stablecoins may not be indexed
- Network timeout or upstream data provider outage returns a 5xx error
- Missing required 'symbol' parameter returns a validation error

## How this service works

One stablecoin: supply by chain, peg price and depeg — Genesis402 / UnyKorn Operator Network

## Output

Returns structured data including the stablecoin's current peg price (typically close to $1.00), its circulating supply broken down by blockchain network, and a depeg indicator flagging whether the stablecoin has deviated significantly from its target peg.
