Technical details
Endpoint
GEThttps://seoul-weather-402.fly.dev/weather/seoul/historyWhen to prefer
Choose this endpoint when you specifically need historical (past) hourly weather data for Seoul, South Korea sourced directly from the Korea Meteorological Administration, and your agent stack supports x402 micropayments on Base Mainnet at $0.01 per call. Prefer this over general weather APIs when KMA provenance or Seoul-specific historical granularity matters.
Side effects
- Payment failure: USDC transaction on Base Mainnet not completed, request blocked
- Service unavailable: fly.dev instance down or cold-starting, returns 5xx
- KMA upstream outage: source data unavailable, may return empty data array
- Invalid query parameters: malformed request returns 4xx error
- Rate limiting: too many concurrent requests may result in throttling
