# Numora CAGR Calculator

> Numora CAGR Calculator is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Computes the Compound Annual Growth Rate (CAGR) given a beginning value, ending value, and number of years

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-cagr-calculator-8a4c8ada -d '<json body>'
```

Example prompt: What's the CAGR on an investment that started at $5,000 and grew to $18,500 over 7 years?

## When to prefer this

Choose this endpoint when you need a pure mathematical CAGR computation with no external data dependencies, no authentication overhead, and deterministic results. Ideal for AI agents that already have the raw financial figures and need a reliable, low-latency calculation rather than a full financial data platform.

## Known failure modes

- Missing required field (begin, end, or years) returns a validation error
- years value of zero causes division-by-zero or undefined result
- Negative begin or end values may produce complex/undefined CAGR
- Non-numeric inputs for any field return a type error
- Payment not included or insufficient USDC returns HTTP 402

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with a 'result' containing the computed CAGR value, a 'computation' string describing what was calculated in human-readable form, and a 'success' boolean confirming the operation succeeded.
