Raindrop's Rainfall & Precipitation Data API
Precipitation data that isn't just guesswork
Most weather APIs post previous forecasts as historical data. We store real-time sensor data for the past 11 years, to give rainfall totals accurate to within 0.05 inches.
Priced by the locations you track — from $10/month for a single point.
Why Raindrop?
Most weather APIs recycle old forecast predictions and call it "historical data." We store actual measurements from real sensors.
Recycled forecast model outputs: essentially past predictions, not measurements.
Actual observed data from 10,000+ NOAA sensors: Doppler radars, satellites, and rain gauges.
Grid-averaged data that misses local variability. Accuracy degrades at point level.
Accurate to 0.05 inches at 1 km resolution, the same data the National Weather Service relies on.
Often 1–2 years of history, or requires expensive enterprise tiers for full access.
11+ years of historical data (Jan 2015 – present) included on all plans. No hidden paywalls.

How locations work
- A location is a lat/lon you save. Requests just need to land within 1 km of one.
- Adding is free while a slot is open. Removals draw on a monthly allowance of 5× your locations, reset on the 1st.
- Every endpoint on your plan works at every location, as often as your rate limit allows. Past 50, Enterprise is quoted to fit.
