How this service works
Stablecoin peg check: price vs USD, deviation in basis points and peg status for USDC, USDT, DAI, USDe and PYUSD from public Ethereum pools (utilpeek by Tanod). Use when an agent must check whether USDC, USDT, DAI, USDe or PYUSD still trades at one dollar, from on-chain pools.
Output
Returns for each requested stablecoin: the current USD price sourced from public Ethereum pools, the deviation from $1.00 expressed in basis points, and a peg status (e.g. pegged / depegged / warning). Returns a 422 error listing supported coins if an unknown symbol is requested.
Example use cases
Pre-trade stablecoin health check
“Before I swap into USDT, can you verify it's still at peg? Show me the current on-chain price and deviation in basis points.”
Depeg alert for DeFi risk monitoring
“Check all five major stablecoins — USDC, USDT, DAI, USDe, and PYUSD — and tell me if any of them have lost their dollar peg right now.”
Arbitrage opportunity scan
“Is DAI trading meaningfully above or below $1 on-chain? Give me the exact price and basis point deviation so I can evaluate an arbitrage.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/fx/stablecoin-peg?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, on-chain peg verification for USDC, USDT, DAI, USDe, or PYUSD specifically sourced from Ethereum liquidity pools rather than centralized exchange prices. Prefer it over generic price feeds when you need basis-point precision on peg deviation and an explicit peg status flag, especially for risk checks before DeFi transactions.
Side effects
- Unknown coin symbol in request → 422 with list of supported coins
- Network/RPC issues fetching on-chain pool data → 5xx error
- Stale pool data if Ethereum node is lagging
- Payment failure (x402) if USDC balance is insufficient
