# Numora CAGR Calculator

> Numora CAGR Calculator is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

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

## Facts

- Endpoint: POST https://numomo.vercel.app/api/financial/cagr
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-cagr-calculator-26ca9dc1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_nj7dt5fE4UNrc6bOBGAcT

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-26ca9dc1 -d '<json body>'
```

Example prompt: What's the CAGR for 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 fast, dependency-free computation of CAGR from raw numeric inputs with no external data fetching. Prefer it over building your own formula when operating inside an agent workflow that supports x402 micropayments on Base, and when you want a clean JSON result with a human-readable computation description alongside the numeric result.

## Known failure modes

- Missing required fields (begin, end, years) returns a validation error
- Passing zero or negative values for begin may cause division errors or nonsensical results
- years = 0 causes division by zero in the CAGR formula
- Non-numeric inputs cause type validation failures
- Negative CAGR (end < begin) may or may not be supported — verify with the API

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