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 geo402-timezone-lookup-838c349b
```

Example prompt: What timezone is the location at latitude 48.8566, longitude 2.3522 in? Give me the IANA timezone name and UTC offset.

## When to prefer this

Use this endpoint when you need to resolve the timezone for a specific geographic coordinate without managing API keys or subscriptions, and you can pay per call via x402/USDC. Ideal for AI agents that need timezone data on-demand without committing to a subscription service.

## Known failure modes

- Missing lat or lon parameter returns 400 Bad Request
- Coordinates out of valid range (lat > 90 or < -90, lon > 180 or < -180) return validation error
- Payment not provided or insufficient USDC balance returns 402 Payment Required
- Remote timezone database unavailable returns 503
- Ocean or polar coordinates may return UTC or nearest timezone approximation

## How this service works

Pay-per-call geolocation utility for AI agents: geocoding, reverse geocoding, timezone lookup, and great-circle distance. No API key, no subscription — agents pay per request via x402 (Base/USDC) or MPP (Tempo/pathUSD).

## Output

Returns the IANA timezone identifier (e.g. 'America/New_York') and the corresponding UTC offset for the provided coordinates, enabling correct local time calculations for any geographic point.
