# CelerAPI Timezone Lookup

> CelerAPI Timezone Lookup is a paid API for AI agents from www.celerapi.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns the current local time, UTC offset, and timezone abbreviation for a given IANA timezone identifier, optionally at a specified point in time.

## 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 celerapi-timezone-lookup-c1a06b76
```

Example prompt: What's the current local time and UTC offset for the America/Chicago timezone right now?

## When to prefer this

Choose this endpoint when you need authoritative, structured timezone data (local time, UTC offset, DST abbreviation) for a known IANA timezone identifier without managing a timezone library yourself. Ideal for lightweight, per-request lookups in agent workflows where installing and maintaining a timezone library is impractical. Priced at $0.001 USDC per call with no API key required, making it accessible for ad-hoc or low-volume use cases.

## Known failure modes

- Invalid or unrecognized IANA timezone name returns an error
- Malformed 'at' datetime query parameter (wrong format) results in a validation error
- Payment not provided or insufficient results in HTTP 402
- Truncated response indicated by 'complete: false' flag in response body

## How this service works

Resolve companies, legal entities and financial reference data using authoritative sources. Machine-native, pay per request, no subscription.

## Output

A JSON object containing the resolved timezone name, current or specified UTC time, corresponding local time, UTC offset in minutes, timezone abbreviation (e.g. EST, CET), and a data version string sourced from the IANA Time Zone Database. Also includes a provenance block with source, license, and freshness metadata.
