# payload402 Geo Lookup (Place/Coordinates to Timezone)

> payload402 Geo Lookup (Place/Coordinates to Timezone) is a paid API for AI agents from payload402.edgebytenet.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-16).

Resolves a place name or lat/lon coordinates to IANA timezone identifier, canonical coordinates, and country metadata using Open-Meteo geocoding.

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 payload402-geo-lookup-place-coordinates-to-timezone-fe2cb36b
```

Example prompt: What's the IANA timezone and coordinates for Istanbul? I need to schedule a meeting in local time there.

## When to prefer this

Use this endpoint when an agent needs a deterministic, authoritative IANA timezone string for a named city or lat/lon pair — especially for scheduling, calendar, or travel logistics tasks where guessing the timezone from an LLM would be unreliable. Prefer this over IP-geolocation endpoints (which infer location from network address) and over asking an LLM to recall timezone data, which can be stale or wrong. Best suited for single-location synchronous lookups rather than batch geocoding jobs.

## Known failure modes

- Ambiguous or misspelled place name returns incorrect or no match
- Providing lat without lon (or vice versa) triggers a validation error
- Very small or obscure localities may not be recognized by Open-Meteo geocoding
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or upstream Open-Meteo unavailability causing 5xx errors

## How this service works

Resolve a place name or lat/lon to IANA timezone and coordinates (Open-Meteo). Use for agent scheduling, travel logistics, and local-time questions without LLM guessing. Not IP geolocation.

## Output

A JSON object with the canonical place name, country, country code, latitude, longitude, IANA timezone string (e.g. 'Europe/London'), and a source field indicating Open-Meteo as the geocoding provider.
