# Numora CAGR Calculator

> Numora CAGR Calculator is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/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

- Endpoint: POST https://numormor.netlify.app/api/financial/cagr
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-cagr-calculator-866aa244
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_hvvCsQNb5wmuvF33Zm8NY

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-866aa244 -d '<json body>'
```

Example prompt: What's the CAGR on an investment that started at $10,000 and grew to $18,500 over 6 years?

## When to prefer this

Choose this endpoint when you need a pure, dependency-free CAGR computation without connecting to market data APIs or financial databases — ideal when you already have the start value, end value, and time period and just need the math done reliably. Prefer over general-purpose calculators when you want a structured JSON response with a human-readable description suitable for agent workflows.

## Known failure modes

- Missing required fields (begin, end, or years) returns a validation error
- Zero or negative years value may cause division-by-zero or invalid math error
- Zero beginning value causes mathematical impossibility (division by zero in CAGR formula)
- Non-numeric input types return schema validation errors
- Payment failure via x402 micropayment protocol returns 402 Payment Required

## 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 boolean success flag, a result object containing the computed CAGR value (typically as a decimal or percentage), and a human-readable computation string describing what was calculated.
