# FastX402 Timezone Offset Lookup

> FastX402 Timezone Offset Lookup is a paid API for AI agents from fastx402.tools, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-27).

Returns the UTC offset (hours and minutes), DST status, and formatted offset string for a given IANA timezone on a specific date.

## 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 fastx402-timezone-offset-lookup-f02f2b80
```

Example prompt: What is the UTC offset for America/New_York on July 15, 2026 — and is it in daylight saving time?

## When to prefer this

Choose this endpoint when you need to programmatically determine the exact UTC offset (including DST awareness) for any IANA timezone on a specific historical, current, or future date, without maintaining a local timezone database. It is especially useful in scheduling, internationalization, and data pipeline enrichment scenarios where DST transitions matter and you need a reliable, pay-per-call service with no account setup.

## Known failure modes

- Invalid or unrecognized IANA timezone name — likely returns an error or empty response
- Malformed date string (not YYYY-MM-DD) — may return a validation error
- Missing required query parameters (timezone or date) — returns 400 bad request
- Date out of supported range — may return unexpected or empty results
- Payment failure via x402 — 402 response if USDC payment is not accepted

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object with the queried timezone name, the date, the UTC offset in whole hours and total minutes, a formatted offset string (e.g. '-04:00'), and a boolean indicating whether daylight saving time is in effect.
