## When to prefer this

Choose this endpoint when you need a quick, real-world city name with coordinates from a global sample — ideal for seeding test data, geography quizzes, map demos, or any scenario requiring a plausible random location. Prefer it over geocoding APIs when you don't have a specific city in mind and just need a valid real-world city. The optional seed parameter makes it suitable for reproducible randomness.

## Known failure modes

- Invalid or unrecognized country code returns no results or an error
- Network timeout from the Cloudflare Worker
- Payment failure via x402 protocol prevents access
- Seed parameter producing no matching city for the given country filter
