Otto AI Stablecoin Watch
x402
Otto AI Stablecoin Watch is a paid API for AI agents from dataendpoints-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Returns hourly-refreshed stablecoin market data with generatedAt/staleness metadata, served by Otto AI's data endpoint infrastructure.
Price / call$0.001
Success—
StatusUnknown
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). Refreshed hourly.
Output
A JSON object with status 'success', a data payload containing stablecoin market metrics and conditions (refreshed hourly), and a meta object including a generatedAt timestamp and staleness indicators.
Example use cases
Example prompt
“Give me the latest stablecoin watch report — I want to see current stablecoin market conditions including any freshness/staleness info on when the data was last generated.”
Technical details
Endpoint
GEThttps://dataendpoints-production.up.railway.app/stablecoin-watchWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.001 USDC) snapshot of stablecoin market data refreshed on an hourly cadence. Prefer this over real-time feeds when near-real-time accuracy is acceptable and cost efficiency matters. Useful for agents monitoring DeFi conditions, stablecoin de-pegging risk, or portfolio context.
Side effects
- Payment not received (402 Payment Required) — agent must send 0.001 USDC via x402 protocol
- Data may be up to ~1 hour stale — check meta.generatedAt for freshness
- Endpoint temporarily unavailable on Railway infrastructure (503/timeout)
- Empty or partial data payload if upstream stablecoin data sources are down
