How this service works
Simple CAGR from start value, end value, and years. Call when annualizing multi-year equity curves offline. Returns cagr as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the computed CAGR as a decimal or percentage, calculated deterministically using the standard CAGR formula ((end/start)^(1/years) - 1) with no external data dependencies.
Example use cases
Backtesting equity curve annualization
“I ran a backtest and my strategy started at 100000 and ended at 340000 over 10 years — what's the compound annual growth rate?”
Comparing two investment options
“Investment A went from 20000 to 45000 in 4 years. What's the CAGR so I can compare it against other options?”
Reporting fund performance to stakeholders
“Our fund started at 5000000 and is now at 8200000 after 3 years. Can you calculate the annualized CAGR for the performance report?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/cagr-simpleWhen to prefer
Use this endpoint when you need a fast, cheap, deterministic CAGR computation with no external data dependencies, no API keys, and no live market data — ideal for offline backtesting, financial reporting pipelines, or any agent workflow that needs annualized return figures on demand for $0.001 per call.
Side effects
- Missing required fields (start, end, or years) results in a validation error
- years = 0 causes a division-by-zero or undefined result
- start = 0 causes a division-by-zero error
- Negative start or end values may produce mathematically undefined or complex results
- Non-integer inputs rejected if schema enforces integer type
- Payment failure (insufficient USDC balance) blocks the request via x402
