How this service works
Live $1-peg deviation for the top USD stablecoins (USDT, USDC, USDS, DAI, USDe, PYUSD, USDD, TUSD, FDUSD by default, or pass your own list): current price, deviation in basis points, 24h high/low, worst 24h deviation, market cap, and an on-peg / stressed / depegged status. Backed by CoinGecko's public API.
Output
Returns for each queried stablecoin: current price in USD, deviation from $1 peg in basis points, 24h high and low prices, worst 24h deviation, market capitalization, and a boolean or label indicating whether the coin is currently on-peg or depegged.
Example use cases
Example prompt
“Check the current peg status for USDT, USDC, and DAI — I want to see how many basis points each is deviating from $1 and whether any of them are considered off-peg right now.”
Technical details
Endpoint
GEThttps://agent402.tools/api/stablecoin-pegWhen to prefer
Use this endpoint when you need real-time peg health for specific USD stablecoins, especially when you need basis-point precision, 24h deviation history, and on-peg/off-peg classification all in one call. Prefer it over generic crypto price APIs when stablecoin stability analysis is the primary goal.
