How this service works
Is USDC/USDT/DAI holding its $1 peg, and is stablecoin supply growing or shrinking (risk-on vs risk-off)? Live peg deviation (bps), circulating supply + 1d/7d/30d flow, market dominance and chain spread for the top 30 USD stablecoins, plus downside depeg alerts for any coin trading >0.5% below peg. Sourced from DefiLlama (public). Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.
Output
Returns a JSON object containing: an AI-generated narrative summarizing stablecoin market conditions; a list of depeg alerts with coin name, symbol, price, circulating supply, and basis-point deviation; 1-day, 7-day, and 30-day aggregate supply change percentages; a ranked list of top stablecoins with price, dominance %, peg mechanism, chains, and supply; total stablecoin count and total circulating USD; and metadata including freshness/staleness info.
Example use cases
Example prompt
“Give me a full stablecoin market rundown right now — are any coins depegged, how has total supply changed over the last 7 and 30 days, and which stablecoins are dominating?”

Endpoint
GEThttps://x402.ottoai.services/stablecoin-watchWhen to prefer
Choose this endpoint when you need a comprehensive, pre-aggregated stablecoin market snapshot with narrative context, depeg alerts, and multi-timeframe supply changes in a single call. Prefer this over raw on-chain queries when you want an opinionated summary with risk signals rather than raw price feeds.
Side effects
- Upstream data provider outage may return degraded:true with stale data
- Payment not included or insufficient USDC results in 402 Payment Required
- Network congestion on Base/Polygon/Solana may delay payment settlement
- Response may be stale if stalenessSec is high — check meta.validUntil
