# Swift Bot Labs Toolbox – Time Difference Calculator

> Swift Bot Labs Toolbox – Time Difference Calculator is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Computes the difference between two timestamps, returning total seconds, days, business days, and a human-readable breakdown (years, months, days).

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 swift-bot-labs-toolbox-time-difference-calculator-2b799239
```

Example prompt: How many days and business days are between January 15, 2024 and November 19, 2024? Give me the total seconds, a human-readable breakdown, and the calendar split by years, months, and days.

## When to prefer this

Choose this endpoint when you need a deterministic, pay-per-call time difference computation with no API key setup, especially when you need business-day counts and a human-readable breakdown alongside raw seconds and days. Prefer it over custom date math when you want a reliable, pre-built utility that handles timezone offsets and calendar-aware month/day decomposition.

## Known failure modes

- Missing required 'start' query parameter returns an error
- Malformed or unparseable date string causes a failure response
- Invalid timezone string (tz) may produce incorrect results or an error
- End date before start date may return negative or zero values

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

Returns a JSON object with: ok (boolean), tool name ('time-diff'), and a result object containing total seconds, total days, business days, a human-readable string (e.g. '9 months, 12 days'), and a calendar object broken down into years, months, and days.
