# Stablecoin Market Data: Circulating Supply, Peg Price & Depeg Status

> Stablecoin Market Data: Circulating Supply, Peg Price & Depeg Status is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-03).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-market-data-circulating-supply-peg-price-depeg-status-5e6d33ca -d '<json body>'
```

Example prompt: Give me a stablecoin market snapshot — show me up to 50 stablecoins with their circulating supply, peg price, and whether any are currently depegged.

## When to prefer this

Choose this endpoint when you need a broad, cross-stablecoin market snapshot — covering supply, peg price, and depeg status — in a single call. It is ideal for monitoring stablecoin health across the entire market rather than looking up a single token. Prefer it over exchange-specific APIs when you need aggregated on-chain supply figures and depeg signals rather than trading price feeds.

## Known failure modes

- Invalid limit value (outside 1–150 range) returns a validation error
- Upstream data source unavailable results in a service error
- Payment of $0.003 USDC not provided triggers a 402 Payment Required response
- Empty result set if no stablecoins are currently tracked
