How this service works
Credit-analyst primitive for agents: compares live top stablecoin DeFi yields (DefiLlama) against the official US Treasury Bill rate (US Treasury Fiscal Data) in one call. Returns the risk-free rate, top on-chain yields, the spread for each, and a verdict on whether on-chain yield currently compensates above risk-free. TradFi + DeFi combined — no other single endpoint does this.
Output
A JSON object containing a plain-language verdict (e.g. 'ON-CHAIN PREMIUM: top stable yields exceed risk-free by >1%'), an array of top yield spreads with pool name, chain, APY percentage, and spread percentage over the risk-free rate, plus the current US Treasury bill rate and its source.
Example use cases
Example prompt
“What's the current macro risk spread — are top on-chain stablecoin pools like Aave v3 USDC on Base actually beating the US Treasury bill rate right now, and by how much?”
Technical details
Endpoint
GEThttps://store.agentexchange.work/macro/risk-spreadWhen to prefer
Use this endpoint when an agent needs a fast, pre-computed macro snapshot comparing the best stablecoin DeFi yields to the US risk-free rate — ideal for portfolio decision support, DeFi opportunity scanning, or macro yield monitoring without needing to aggregate multiple data sources manually.
Side effects
- Upstream yield data unavailable — stale or missing on-chain APY data
- Treasury rate feed unavailable — risk-free benchmark cannot be fetched
- Payment not received — x402 micropayment in USDC not completed, returns 402
- Malformed response if DeFi data source temporarily returns unexpected schema
