## 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-retirement-savings-calculator-3fc31eee -d '<json body>'
```

Example prompt: I have $85,000 saved right now, I contribute $12,000 per year, my expected annual return is 7%, and I plan to retire in 25 years — how much will I have at retirement?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, pure-math retirement projection with no external data dependencies — ideal when you already have the interest rate, current savings, contribution amount, and time horizon and just need the compound growth math computed instantly without any market data lookups or account integrations.

## Known failure modes

- Missing required fields (rate, years, savings, or contribution) returns a validation error
- Non-numeric values for rate or savings cause a 400 error
- Negative years or zero rate may produce unexpected mathematical output
- Network timeout if the Vercel serverless function is cold-starting

## 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 human-readable computation description, and a result object containing the projected retirement balance or growth breakdown computed purely mathematically from the provided rate, years, savings, and contribution inputs.
