Technical details
Endpoint
POSThttps://keyronne.com/api/weather?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need weather data (current conditions or forecasts) for any global location without managing API keys. It is ideal for single-call, no-auth weather lookups with flexible location input (city name or coordinates), backed by MET Norway's open data. Prefer it over other weather APIs when you want no-key access and are working within the x402 micropayment ecosystem.
Side effects
- Unknown city name returns an error or empty result
- Lat/lon out of valid range (-90 to 90, -180 to 180) causes validation failure
- Requesting more than 90 hourly or more than 10 daily entries is rejected
- Payment failure returns HTTP 402
- Missing both city and lat/lon causes a bad request error
