The multi-source weather API.

GET /v1/weather/point

Single-shot current weather for a coordinate. Safety-critical fields (wind, gust, precipitation, visibility) are pessimistically merged across providers; every snapshot carries the contributing provider in its `source` field.

• •All wind speeds are m/s (ICAO/EASA aviation standard).
• •Optional fields are omitted from the JSON when the upstream provider cannot supply them - treat any missing key as unknown, never silently zero.
• •`windProfile` carries the upper-air interpolation. Pro tier only.
• •`nowcast` is populated when a precipitation nowcast is available for the coordinate. `radarCoverage` is `"ok"` for real ground-based radar (regions where we operate a national adapter) or `"model-fallback"` for a global model nowcast; absent when no nowcast is available at all.
• •`providerStatus[]` lists every upstream queried for this response with its current health (independent of whether it contributed a field).

GET /v1/flight-score

Advisory 0-100 drone-flight score with conservative thresholds blending wind and gusts (including the 25-150 m altitude corridor), precipitation, visibility, temperature, and the geomagnetic Kp index. Returns reasons on every degraded field. Not legal permission to fly.

}

• •`status` is one of `good` (≥70), `caution` (40-69), `bad` (<40), or `unknown` when a critical field is unavailable.
• •`mode` is `"pro"` when radar nowcast and the 25-150 m altitude wind corridor are factored into the verdict; `"free"` when the score uses only signals the free-tier UI surfaces.
• •`region` is the ISO 3166-1 alpha-2 country code when the `country` hint resolves to a known national authority, or `"generic"` otherwise. `legalNotice`, `officialLinks`, and `authorityName` reflect that resolution.
• •`authorityName` is the human-readable name of the national drone authority for the resolved region (e.g. `"FAA"`, `"Transportstyrelsen / LFV"`), or `null` for the generic fallback. The registry covers 30+ countries; outside it `officialLinks` falls back to the EASA geo-zones map.

GET /v1/activity-score

Two-axis conditions assessment for a chosen activity (drone, paraglider, hang-glider, speedflying, kitesurf, windsurf, wing-foil). `safety` answers "is it safe?"; `quality` answers "is it worth going?" - the axes diverge for wind- and thermal-dependent sports. Per-axis reasons plus a data-confidence flag. Advisory only; not legal permission to fly.

}

• •`safety.status` is one of `safe` / `caution` / `dangerous` / `unknown`; `quality.status` is one of `ideal` / `good` / `marginal` / `flat` / `unknown` (`flat` = not worth it, e.g. too light to ride).
• •For `drone` the two axes are identical (`quality` mirrors `safety`); for free-flight and wind-water activities they diverge - a calm day can be `safety: safe` yet `quality: flat`.
• •`confidence` is `full` / `partial` / `low` - `partial` when an activity's required inputs are missing (no thermal data for a paraglider, or no `shoreBearingDeg` for a wind-water sport). The engine never fabricates missing data.
• •Each reason carries an `axis` (`safety` or `quality`) and a `severity` (`info` / `warning` / `critical` / `blocking`; `blocking` zeroes the quality axis).
• •`region`, `legalNotice`, `officialLinks`, and `authorityName` follow the same country resolution as /v1/flight-score.

}

• •`category` is one of `aerial-powered` / `free-flight` / `wind-water` / `freefall`. The list grows over time - treat it as the source of truth for valid `activity` ids.

GET /v1/notam/point

Drone-relevant airspace restrictions (currently US Temporary Flight Restrictions via the FAA) visible from the coordinate. Honest three-state status: `not_supported` outside integrated countries, `active` when something intersects, `ok` when coverage exists and nothing does. Advisory only - never a substitute for the official source.

  "disclaimer": "Advisory only. NOTAMs and TFRs may be added between checks. Always verify on the official FAA source before flight."
}

• •`status` is `not_supported` for any country without a NOTAM integration (everything except the US today) - the response still carries `disclaimer` and an empty `notams` array, never an error.
• •`status` is `ok` when the country is covered but no drone-relevant items intersect, and `active` when at least one does. Records are sorted critical, then warning, then info, then by ascending `distanceKm`.
• •Each record's `kind` is `"tfr"` for FAA Temporary Flight Restrictions or `"notam"` otherwise; `validUntil` is omitted for open-ended restrictions.
• •FAA TFR data activates as the upstream feed is wired into the deployment. Until then US points resolve to `ok` with an empty list - coverage exists, no records are surfaced. The `disclaimer` is attached on every response regardless.

GET /v1/airspace/zones

Drone-relevant airspace zone geometry for a country, sourced from national authorities - control zones, restricted and danger areas, and drone-specific UAS zones as GeoJSON features ready to render or run point-in-polygon against. Covers 15 countries today; an unsupported country returns 404 with the supported list, never a fabricated 'all clear'. Advisory only - always confirm on the official authority map.

• •`country` is required and accepts any ISO 3166-1 alpha-2 code; an unsupported country returns 404 `COUNTRY_NOT_SUPPORTED` with the current supported list - never an empty "all clear". `GET /v1/airspace/zones/countries` returns that list on its own.
• •Each feature's `properties.type` is a discriminated zone kind (`ctr`, `atz`, `tiz`, `restricted`, `danger`, `esu_required`, …). `lowerLimit`/`upperLimit` follow the `{ kind: "sfc" | "unlimited" | "altitude" | "flight_level" }` shape; `scheduledActivation: true` marks zones active only during published activations.
• •Advisory only. Zone coverage and currency vary by national source - this endpoint never asserts an area is clear to fly. Always confirm on the official authority map before flight.

• •When the upstream feed is degraded the response still includes the resolved `stations[]` plus an `error` string in place of empty `metar`/`taf` arrays.

Rate limits & quotas

Two layers protect your traffic and our upstream providers.

Every successful response includes X-RateLimit-Limit-Month, X-RateLimit-Remaining-Month, and X-RateLimit-Remaining-Burst. Reading them is the cheapest way to pace traffic without polling a separate usage endpoint.

Errors

Errors share a single envelope: a stable error code and a human-readable message. Retry timing for 429 responses is in the Retry-After response header (in seconds), not in the body.

{
  "error": "RATE_LIMITED",
  "message": "Burst limit exceeded"
}

Multi-source merge

Safety-critical fields - wind, gusts, precipitation, visibility - are merged pessimistically across providers. We take the more flight-conservative reading (max for wind/gust/precipitation, min for visibility) and surface the primary source on the snapshot so your client can render attribution. Non-safety fields like temperature and dew point come from the primary provider so the snapshot stays internally coherent.

When a provider can’t answer (region outside its extent, upstream timeout) the contributing key is simply omitted from the JSON - treat any missing field as unknown rather than zero. We never silently substitute a different region or interpolate across gaps. Radar nowcast is labelled explicitly: radarCoverage: "ok" marks regions where we operate a national ground-radar adapter, "model-fallback" marks a global model nowcast used outside those regions, and the field is absent when no nowcast is available at all. Your client can decide whether to display the model fallback or hide it.

Data sources & attribution

DroneInfo aggregates authoritative meteorological forecasts, aviation observations, and national radar nowcasts from official government agencies. Attribution is carried on every reading via the source field on each weather snapshot, plus the per-request providerStatus[] array that reports the health of every upstream queried for the response.

The radar source reference documents the national networks we query: format, resolution, cadence, licence and required attribution, plus how each one distinguishes no coverage from no measurement from a measured zero.

Code samples

Server-side examples. Read the key from an environment variable; never ship it in client bundles.
