Technical details
Endpoint
POSThttps://agent402.tools/api/cagrWhen to prefer
Use this endpoint when you need a precise CAGR and total growth figure given explicit start value, end value, and duration in years — ideal for financial analysis, investment benchmarking, or business KPI reporting when you already have the raw data points.
Side effects
- beginValue or endValue is zero or negative — undefined result or division by zero
- years is zero or negative — invalid exponent, computation fails
- missing required fields returns a validation error
- non-numeric inputs cause a 400 bad request
