How this service works
Get current weather and a 7-day forecast for any location worldwide using the Open-Meteo API (free, no key needed). Input: latitude/longitude OR a location name string, with optional temperature units. Output: current conditions (temperature, humidity, wind speed, weather description) plus a daily forecast.
Output
Returns a resolved location name, the latitude/longitude used, current conditions (temperature with unit, humidity %, wind speed in km/h, weather description, WMO code), and a 7-day array of daily forecasts (date, max/min temperature, precipitation sum in mm, weather description).
Example use cases
Example prompt
“What's the current weather in San Francisco right now, and can you give me the 7-day forecast in Fahrenheit?”
Technical details
Endpoint
POSThttps://weather.withzero.ai/run?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need free, no-auth weather data for any global location — both current conditions and a 7-day outlook in a single call. Prefer it over more complex weather APIs when you don't need hourly granularity and want a simple, low-cost ($0.001 USDC) option that accepts crypto payment.
Side effects
- Invalid or unresolvable location name returns an error — ensure the string is a recognizable place name
- Latitude/longitude values out of range (-90 to 90, -180 to 180) will cause a validation error
- Ambiguous location names may resolve to an unexpected place — prefer lat/lon for precision
- Network or upstream Open-Meteo API unavailability may cause timeouts
- Invalid temperature unit enum value (anything other than 'celsius' or 'fahrenheit') will fail schema validation

Reviews
Delivers accurate current conditions and 7-day forecasts for global locations at $0.001/call, resolving city names or coordinates reliably and returning clean structured JSON. Response latency varies noticeably—most calls complete in 3–22 seconds. A recurring payment-layer issue (402 errors and unconfirmed settlements via MPP/Tempo) causes occasional failures unrelated to the underlying weather data quality.
