One API, multiple national met sources. Compare, don’t gamble.
Authoritative meteorological and aviation data in a single REST endpoint, merged worst-case on safety-critical fields. Every response carries per-source attribution and an explicit list of unavailable fields, so your application can audit data quality field by field instead of trusting a black-box composite.
What single-source weather APIs leave on the table.
DroneInfo aggregates national meteorological services into one normalised envelope. When providers disagree on a safety-critical field, we apply a pessimistic merge and surface the contributing sources, so your application can present a single conservative reading without losing provenance.
Multi-source merge
Authoritative meteorological and aviation feeds, blended worst-case on safety-critical fields so the reading you ship is the one your pilots can trust.
Real-radar nowcast
A 2-hour precipitation nowcast from national ground radar where we run an adapter - Norway/Sweden, Germany, UK, USA, Canada, Denmark, Japan - with an honest model fallback everywhere else. radarCoverage tells you which one answered.
Honest unavailable
When coverage is missing, the field returns null with a reason. No silent interpolation across coverage gaps.
Self-hosted forecast for EU
Our forecast model runs on dedicated infrastructure. Sub-200 ms p50 latency in Europe. Aviation METAR/TAF and the Kp index included on every tier.
How DroneInfo compares to single-source alternatives.
A side-by-side review of multi-source meteorological data against the typical single-source weather API.
A single envelope across every provider.
Each response carries the contributing sources, an explicit unavailable array, and units that remain consistent across regions.
- REST and JSON. Stable schema across all regions.
- Per-field source attribution and timestamps.
- Aviation METAR and TAF available from the Hobby tier.

}From your first call to production scale.
A permanently free tier, paid plans from $9 a month, and no overage charges. Every plan ships the same multi-source data and the same per-source attribution.
The same endpoint runs our pilot application.
DroneInfo’s consumer application for drone pilots reads from the same public API. The pessimistic merge, the per-response source attribution, and the null-with-reason gap handling are visible in production today.
Live forecasts for San Francisco, London, and Tokyo render directly from the endpoint your application would consume.
