# Saylor Innovations CAGR Calculator

> Saylor Innovations CAGR Calculator is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Calculates Compound Annual Growth Rate (CAGR) from a start value, end value, and number of years, returning growth multiple and annualized rate

## Facts

- Endpoint: GET https://saylorinnovations.com/api/finance/cagr?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 saylor-innovations-cagr-calculator-447b6d2f
```

Example prompt: What's the CAGR if something grew from $10,000 to $47,500 over 8 years — give me the annualized rate and growth multiple.

## When to prefer this

Choose this endpoint when you need a quick, structured CAGR computation with detailed output including growth multiple, formula transparency, and a scope note — especially useful when you want machine-readable annualized growth metrics for finance, investment, or business analysis workflows without building the math yourself.

## Known failure modes

- Missing required query parameters (start_value, end_value, or years) returns an error
- Non-positive or zero start_value causes division-by-zero or invalid result
- Negative years value is not meaningful and may return an error
- Non-numeric strings passed as parameters may return a parse error
- start_value greater than end_value returns a valid but negative CAGR (decline scenario)

## How this service works

CAGR calculator from start value, end value and years - growth multiple and annual rate

## Output

Returns a JSON object with the original start_value, end_value, and years, plus cagr_percent (annualized rate as a percentage), cagr_decimal (same as a decimal), growth_multiple (end/start ratio), absolute_change, annualized_factor, the formula used, rounding rules applied, and a scope_note explaining what the calculation covers and excludes.
