## When to prefer this

Choose this endpoint when you need a quick, no-signup, pay-per-call weather lookup for a city and are already operating in an x402 micropayment environment on Base. Ideal for agents that need weather data without managing API keys or subscriptions, and where cost-per-call at $0.002 USDC is acceptable.

## Known failure modes

- Missing or invalid city name returns an error or empty result
- Payment failure via x402 results in HTTP 402 with no data returned
- Unknown or misspelled city may return null or error response
- Service unavailability on duckdns host may result in connection timeout
