## 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 pennyrail-time-diff-seconds-86f0c073 -d '<json body>'
```

Example prompt: How many seconds are there between January 1, 2024 and March 15, 2024?

## When to prefer this

Use this endpoint when you need a precise seconds-based time difference between two dates as a paid microservice call, particularly within x402-compatible agent workflows where per-call micropayment settlement is acceptable and you want a simple, stateless computation without standing up your own date-arithmetic logic.

## Known failure modes

- Missing or malformed date inputs cause a 400-level error
- Invalid date format results in a parsing error response
- Future-to-past ordering may return a negative value or error depending on implementation
- Payment failure (x402) if USDC balance is insufficient for the $0.001 per-call fee

## How this service works

Machine-readable settlement service

## Output

Returns a numeric value representing the total number of seconds between the two provided dates, useful for precise time-delta calculations in scheduling, countdowns, or duration measurement.
