# Timezone by Coordinate

> Timezone by Coordinate is a paid API for AI agents from mcpfax-utility.bowling-anthony.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Converts geographic coordinates (latitude/longitude) to IANA timezone identifier, UTC offset, and current local time.

## Facts

- Endpoint: GET https://mcpfax-utility.bowling-anthony.workers.dev/v1/timezone
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 timezone-by-coordinate-5a7dbcd9
```

Example prompt: What timezone, UTC offset, and current local time are at coordinates 48.8566° N, 2.3522° E?

## When to prefer this

Use this endpoint when you have a lat/lon pair and need to determine the timezone programmatically — ideal for enriching GPS data, scheduling across locations, or converting coordinates from device telemetry into human-readable timezone context. Prefer this over a city/place name lookup when you have raw coordinates rather than a named location.

## Known failure modes

- Coordinates out of valid range (lat not in -90 to 90, lon not in -180 to 180) return a validation error
- Coordinates in open ocean with no defined timezone may return UTC or an error
- Missing or malformed coordinate fields return a 400-level error
- Payment failure or insufficient USDC balance returns a 402 error

## How this service works

Timezone by coordinate — Coordinates → IANA timezone, UTC offset, local time.

## Output

Returns the IANA timezone string (e.g. 'America/New_York'), the UTC offset in hours (e.g. -5 or +5.5), and the current local datetime at the given coordinates.
