# EU Weather & Geo (x402) — City Geocoding

> EU Weather & Geo (x402) — City Geocoding is a paid API for AI agents from eu-weather-geo.frcompanycheck.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Geocodes a city name to latitude, longitude, country, timezone, and population data using GeoNames open data, paid per call in USDC via x402.

## Facts

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 eu-weather-geo-x402-city-geocoding-f8b0bc47
```

Example prompt: What are the coordinates and timezone for Lyon, France? I want up to 3 matching cities returned.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call city geocoder with no API key or account setup, especially when you also need timezone data alongside coordinates. Ideal for AI agents that need to resolve a city name before calling the weather forecast sibling endpoints on the same service. Compared to full geocoding APIs, it is optimized for city-level lookup rather than street-level address resolution.

## Known failure modes

- City name not found — empty results array returned, no charge
- Invalid or misspelled query returns zero results
- Country filter mismatch returns empty results
- Limit parameter out of range (must be 1-20) may return error or default
- x402 payment failure means request is not processed and no charge is incurred

## How this service works

Weather and geo utilities for AI agents, paid per call in USDC via x402 (no account, no API key): current weather and up-to-9-day daily forecasts for any city or lat/lon (MET Norway open data, CC BY 4.0), city geocoding with time zones (GeoNames, CC BY 4.0) and sunrise/sunset. Errors are never charged.

## Output

Returns a JSON object with the query string and an array of matching city results, each containing latitude, longitude, city name, country code (e.g. 'FR'), capital flag, IANA timezone string (e.g. 'Europe/Paris'), and population count.
