How this service works
QuantOracle: crypto/apy-apr-convert
Output
Returns the converted interest rate value (APY or APR) based on the input rate and compounding frequency, enabling direct comparison of crypto yield rates expressed in different formats.
Example use cases
Example prompt
“Convert an APR of 18.25% compounded daily to its equivalent APY — I want to compare it against a lending platform quoting 19.5% APY.”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/crypto/apy-apr-convertWhen to prefer
Use this endpoint when you need to mathematically convert between APY and APR for crypto or DeFi contexts, especially when comparing yields across protocols that quote rates differently. Ideal when compounding frequency matters (daily, monthly, continuously) and you need a precise numeric result rather than an estimate.
Side effects
- Invalid or negative input rate returns a 400 error
- Unsupported compounding frequency value rejected
- Missing required conversion direction or rate field causes validation error
- Extremely large rates may produce overflow or precision errors
