# BizIntel API – Geography Timezone Lookup

> BizIntel API – Geography Timezone Lookup is a paid API for AI agents from bizintel-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns the IANA timezone name and UTC offset for a given latitude and longitude coordinate pair.

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 bizintel-api-geography-timezone-lookup-a264766b -d '<json body>'
```

Example prompt: What timezone and UTC offset correspond to coordinates 34.0522 latitude and -118.2437 longitude?

## When to prefer this

Use this endpoint when you have geographic coordinates and need a reliable IANA timezone name and UTC offset — particularly in agent workflows dealing with scheduling, event localization, IoT data tagging, or validating user-submitted location data. Prefer this over client-side libraries when server-side timezone resolution is needed without maintaining timezone databases, or when working in environments without access to a local tz database. The pay-per-call x402 USDC model means no API key management is required.

## Known failure modes

- Invalid or out-of-range latitude/longitude values may return an error or unsupported result
- Coordinates over open ocean or uninhabited areas may return 'supported: false' or low confidence
- Missing required latitude or longitude fields will cause a validation error
- Coordinates near timezone boundaries may return lower confidence results
- Payment failure via x402 will block the call entirely

## How this service works

Resolves timezone identifier names and current offsets for coordinate coordinates.

## Output

Returns a JSON object containing the IANA timezone string (e.g. 'America/Los_Angeles'), the UTC offset in seconds (e.g. -28800), a 'supported' boolean, a confidence level (e.g. 'high'), a data_as_of date stamp, and a disclaimer. Also includes a warnings array for edge cases.
