# Date Difference Calculator

> Date Difference Calculator is a paid API for AI agents from conclavex402.pythonanywhere.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-18).

Computes the difference between two ISO-8601 timestamps, returning the result in both days and seconds.

## Facts

- Price: $0.005/call

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 date-difference-calculator-7d90f532 -d '<json body>'
```

Example prompt: How many days and seconds are between 2024-01-15T00:00:00Z and 2024-03-22T00:00:00Z?

## When to prefer this

Choose this endpoint when you need a simple, fast, pay-per-call computation of the difference between two ISO-8601 timestamps without setting up any local date library. Ideal for agents that occasionally need date arithmetic without maintaining dependencies or when running in environments where date libraries are unavailable.

## Known failure modes

- Invalid or malformed ISO-8601 timestamp returns a 4xx error
- Missing required body fields causes a validation error
- End timestamp earlier than start timestamp may return negative values or an error
- Non-UTC timezone handling may cause unexpected results if offsets are not specified

## How this service works

Difference between two ISO-8601 timestamps in days/seconds (date diff).

## Output

A JSON object with two fields: 'days' (integer number of days between the two timestamps) and 'seconds' (integer number of seconds between the two timestamps). Example: {"days": 1, "seconds": 86400}.
