How this service works
Live DEX price vs the $1.00 peg for major USD-pegged stablecoins on Base (USDC, USDT, DAI, USDbC). A depeg is silent — balanceOf doesn't change, only what it's worth does — so an agent parked in stables reprices everything off a stale $1. Reports per-coin deviation in basis points and a healthy/watch/depeg status, worst-case across the set. A feed outage reads as 'unknown', never a healthy peg. Pass symbol= for one coin. Not financial advice.
Output
Returns per-coin data including live DEX price, deviation from $1.00 in basis points, and a status label (healthy/watch/depeg). Also reports the worst-case status across the monitored stablecoin set. If a price feed is unavailable, the status is reported as 'unknown' rather than defaulting to healthy.
Example use cases
Pre-trade stablecoin safety check
“Before I swap into USDC on Base, can you check if it's still holding its $1 peg on the DEX? I want the basis-point deviation and whether it's flagged as healthy or at risk.”
DeFi agent portfolio repricing
“My agent is holding DAI and USDbC on Base — can you pull their live DEX prices so I know if they're still worth $1 each, or if I need to rebalance?”
Depeg alert during market stress
“Markets are moving fast — can you check all four major stablecoins on Base right now and tell me if any of them are depegging? Give me the worst-case status across the whole set.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/stablecoin-peg?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or DeFi system needs to verify stablecoin purchasing power before executing trades, pricing assets, or reporting portfolio value — especially when a silent depeg (where balanceOf is unchanged but market value has fallen) would cause mispricing. Prefer this over static $1 assumptions whenever operating in volatile market conditions or during periods of systemic DeFi stress.
Side effects
- Price feed outage returns 'unknown' status rather than a healthy peg signal
- Invalid symbol parameter returns an error or empty result
- Network latency may cause slightly stale DEX prices
- Only covers Base chain — stablecoin pegs on other chains not reflected
