## 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 geocode-place-name-to-coordinates-country-timezone-and-population-09e53d80 -d '<json body>'
```

Example prompt: Look up the coordinates, country, timezone, and population for Nairobi and return up to 5 results.

## When to prefer this

Choose this endpoint when you need structured geographic metadata (coordinates, timezone, country, population) from a human-readable place name, especially within a pay-per-call micropayment context using x402. Prefer it over raw geocoding APIs when you also need timezone and population in a single call, or when you are operating in an agentic pipeline that already handles x402 payments.

## Known failure modes

- Place name not found or too ambiguous — returns empty results array
- Limit parameter out of range (below 1 or above 10) — may return error or be clamped
- Misspelled or non-existent place name — returns no results
- Payment not completed via x402 protocol — request rejected before processing
- Rate limiting or network timeout on the upstream geocoding provider
