Rainbow’s developer platform offers a Tiles API for map layers, a Nowcast API with minute-level precipitation forecasts up to four hours, and a Weather API for standard forecast variables. It supports global coverage and common map SDKs.
Every API has a free tier: 30,000 map tiles per month and 5,000 requests monthly for Nowcast and Weather. Pay-as-you-go rates are $0.20 per 1,000 tiles and $0.10 per 1,000 requests for each REST API.
Weather forecasts are probabilistic and can be wrong. Do not rely on a single API for emergency, aviation, marine, medical, or other safety-critical decisions without authoritative local sources.
