## 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 worlddata402-geocoding-c8b654bf
```

Example prompt: Can you geocode 'Paris, France' and give me its latitude and longitude coordinates?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call geocoding without a subscription, especially in agent workflows that already use x402 USDC micropayments on Base mainnet. It is a good fit when you need to enrich location strings with coordinates on demand, and you want to avoid committing to a monthly geocoding plan. Prefer alternatives like Google Maps or Mapbox Geocoding API if you need batch geocoding, high-volume throughput, or autocomplete suggestions.

## Known failure modes

- Ambiguous query with multiple matching places may return unexpected results or the first best match
- Unrecognized or misspelled place names may return empty results or an error
- Missing required 'q' parameter returns a 400-level error
- Payment failure over x402 protocol returns a 402 Payment Required response
- Rate limits or service unavailability may cause 5xx errors

## How this service works

Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).

## Output
