## 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 delx-commerce-simple-cagr-calculator-f9c7fe3b -d '<json body>'
```

Example prompt: What's the CAGR for an investment that started at 100 and ended at 150 over 3 years?

## When to prefer this

Choose this endpoint when you need a fast, low-cost, pay-per-call CAGR computation with no API key or signup required, especially in autonomous agent workflows that use x402/USDC micropayments. Prefer it over building your own formula when you want a verifiable, schema-tagged result for auditability.

## Known failure modes

- Missing required fields (start, end, or years) returns an error
- years value of zero causes division-by-zero error
- Negative start or end values may yield mathematically undefined results
- Non-integer inputs may be rejected if the schema strictly validates types
- Network or payment failure via x402 protocol returns 402 Payment Required

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the computed CAGR as a decimal (e.g. 0.1447 for ~14.47%), along with the original start value, end value, and number of years, conforming to schema 'delx/util-cagr-simple/v1'.
