Radar-derived precipitation intelligence

Rain Monitoring API for Business

Near-real-time radar-derived precipitation data for operational systems, applications, and business locations.

Monitor fixed locations or geographic areas, retrieve current rain intensity, and identify temporary radar-coverage interruptions through a simple API.

Available for selected business integrations and pilot projects.

Built for operations

A focused signal for rain-sensitive decisions

Get the information your systems need without turning every operational decision into a weather-data project.

Radius-based rain intensity

Evaluate current precipitation for a latitude, longitude, and configurable search radius—not just a generic city forecast. Depending on the integration, optional outputs could also include distance to precipitation, approximate precipitation-covered area, and the types detected within the radius: rain, mixed precipitation, snow, or freezing rain.

Continuous monitoring

Check multiple fixed business locations at the cadence your operation requires.

Honest availability

Differentiate current data, temporary source interruptions, and locations outside supported coverage.

Simple integration, adaptable delivery

Use concise JSON responses in dispatch, routing, dashboards, or automated workflows. Batch requests, threshold alerts, and custom integrations can be provided depending on the use case.

Clear by design

A useful answer in one request

Send a coordinate and radius. Receive a compact result with the latest processed timestamp, coverage state, and rain intensity when current radar data is available.

coverage: 1Current radar data is available
coverage: 0Radar data is temporarily unavailable
coverage: -1The location is outside supported coverage

The example shows the intended production API shape. Distance to precipitation, precipitation-covered area, and types within the radius—rain, mixed precipitation, snow, or freezing rain—could be added as optional fields. Authentication, response fields, and delivery options are finalized for each integration.

Reliability without ambiguity

High-availability infrastructure. Transparent source status.

Commercial deployments can be operated on monitored, high-availability API infrastructure. API-platform availability and radar-data availability are reported separately.

No stale data presented as current. When a source is delayed or unavailable, the API can report that condition explicitly.

API platformMonitored production infrastructure

Radar sourcesAvailability reported independently
Explicit status

The underlying observations are supplied by national and regional meteorological services. Maintenance, repairs, transmission problems, or other external issues can temporarily affect radar-data availability.

Operational use cases

Turn current rain into a business signal

Designed for teams that need location-specific precipitation data inside real workflows—not another consumer weather screen.

01

Delivery & logistics

Use current rain conditions in dispatch, courier operations, ETA calculations, and customer communication.

02

Construction & field work

Track precipitation around outdoor sites and trigger internal operating procedures.

03

Events & venues

Continuously monitor locations and react when rain begins or intensifies.

04

Mobility & fleets

Integrate precipitation information into routing, safety, and fleet-management workflows.
