How this service works
Monitor stablecoin peg deviation from $1 across USDT, USDC, DAI and more, flagging depegs in real time - an exit-risk signal for agents holding stables that LLMs cannot know. stablecoin depeg, peg deviation, usdc depeg, usdt peg, stablecoin monitor, depeg alert Accepts payment on Base or Solana — either network works.
Output
A structured response containing the current price of each monitored stablecoin, its deviation from the $1 peg (in absolute and/or percentage terms), a depeg flag indicating whether the deviation exceeds a risk threshold, and metadata such as the stablecoin name and symbol. Useful for agents to assess exit risk before transacting with or holding stablecoins.
Example use cases
Example prompt
“Before I move funds, check if USDC, USDT, and DAI are all holding their $1 peg right now — flag anything that's deviating more than usual.”
Technical details
Endpoint
GEThttps://api.x402node.dev/market/stablecoin-depegWhen to prefer
Use this endpoint when an AI agent needs to assess whether stablecoins it holds or is about to transact with are maintaining their $1 peg. Ideal before executing DeFi trades, stablecoin swaps, or large transfers involving USDT, USDC, or DAI. Prefer this over general crypto price endpoints because it is purpose-built for depeg detection with explicit risk-flagging logic rather than raw price data alone.
Side effects
- Price feed unavailable — upstream market data source is down, returning 503 or partial data
- Invalid stablecoin symbol provided — returns 400 with error message
- Rate limit exceeded — returns 429 if called too frequently
- Network timeout — real-time feed latency causes delayed or empty response
- Payment not fulfilled — returns 402 if the $0.005 USDC micropayment is not completed
