Weather — entry 001 of 31
Weatherstack
Weatherstack (now operated under the APILayer umbrella) delivers real-time, historical, and forecast weather for millions of cities worldwide, plus marine/tide data and a bulk lookup endpoint for batch requests. It also absorbed the former APIXU service, whose users were migrated onto this platform. Documentation and account management now live on docs.apilayer.com rather than weatherstack.com itself.
