## 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 x402-toolbox-age-calculator-6f9cf6a6
```

Example prompt: How old is someone born on March 15, 1990 — give me their exact age in years, months, and days as of today?

## When to prefer this

Choose this endpoint when you need a quick, no-signup deterministic age or elapsed-time calculation paid micro-cost per call via USDC on Base; ideal for AI agents that cannot use a free date library but need a hosted, trustless computation with cryptographic payment as identity — no API key management required.

## Known failure modes

- Invalid or unparseable date string returns an error response
- Missing required date parameter results in a bad request error
- Future dates may return zero or negative values depending on implementation
- Payment failure via x402 returns a 402 status before computation occurs
- Malformed schema parameter yields no meaningful calculation

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with ok and paid status flags, along with computed age or elapsed time data including years, months, and days derived from the provided date input.
