Frequently asked questions
MeteoFeed is a commercial multi-country weather API — one bearer token for 195 countries plus 26 territories, 11 forecast models, and a wide range of weather and environmental data. Here is what it does, in plain terms. For the full machine-readable reference see /llms.txt, the API docs and the OpenAPI spec.
What is MeteoFeed?
MeteoFeed is a commercial multi-country weather API. It aggregates authoritative national meteorological services and global open-data models behind a single bearer token, so you integrate weather once and get consistent JSON for every country. Coverage spans all 195 sovereign states plus 26 inhabited territories — 221 entities — across every inhabited continent.
Which countries and regions does MeteoFeed cover?
Every sovereign state (195) plus 26 inhabited territories, on every inhabited continent and every island nation. The Netherlands, Germany and Belgium use native national pipelines (KNMI, DWD, RMI); everywhere else uses ECMWF Open Data forecasts, Copernicus CAMS air quality, NOAA METAR observations and NOAA GHCN climate, with NASA GIBS satellite radar and GDACS hazard tracking. You query any location by latitude/longitude, postcode or place name.
What kinds of weather data does MeteoFeed provide?
A wide range of weather and environmental data from one API: current observations, hourly and daily forecasts, severe-weather warnings, precipitation radar, marine wave forecasts and daily sea-surface temperature, air quality and pollen, sun position with UV index and solar-PV yield, climate normals, multi-decade historical archives, geocoding, worldwide typhoon and tropical-cyclone tracking, space weather with an aurora forecast, earthquakes, tsunamis, volcano alerts, and Alpine avalanche bulletins.
Which forecast models can I use, and can I pick a specific one?
Yes. The default best_match waterfall serves the best regional model automatically (KNMI HARMONIE over the Netherlands, DWD ICON-D2 over central Europe, ECMWF IFS elsewhere). You can also pin or compare 11 direct-from-source models with the ?model= parameter: ECMWF IFS and AIFS (an AI model), NOAA GFS and HRRR, Météo-France ARPEGE, AROME and AROME-OM, Environment Canada GEM and HRDPS, MET Norway MEPS, DMI HARMONIE-DINI, and GeoSphere Austria. For example: /v1/forecast?lat=52.1&lng=5.1&model=gfs.
Where does the data come from, and is it licensed for commercial use?
From authoritative public sources only — KNMI, DWD, RMI, ECMWF Open Data, Copernicus CAMS, MeteoAlarm, EUMETNET OPERA, NOAA (METAR, GHCN, GFS, HRRR, SWPC, OISST), USGS, NASA GIBS, Environment Canada, Météo-France, MET Norway and DMI, among others. Every source is CC-BY, public-domain or otherwise cleared for commercial redistribution, so MeteoFeed is built to be resold commercially with attribution.
How much does MeteoFeed cost?
There are four tiers: Free (750 requests per month, no credit card), Basic (EUR 30 per month, 7,500 requests), Pro (EUR 50 per month, 30,000 requests) and Business (EUR 249 per month, 1,000,000 requests, with annual billing available). Every tier includes all data domains and all 11 forecast models; higher tiers raise the request quota and the historical-archive depth.
Is there a free weather API tier?
Yes. The Free tier gives 750 requests per month with no credit card, full access to every endpoint and all forecast models, and a 3-year climate window. It is intended for evaluation and low-volume apps; you upgrade only when you need more requests or deeper history.
How do I get an API key and make my first call?
Sign up, verify your email and pick the Free tier, and you immediately get an mtfd_ bearer key. Then call, for example, GET https://api.meteofeed.com/v1/current?lat=52.37&lng=4.90 with the header "Authorization: Bearer mtfd_your_key". The whole flow takes under five minutes.
What format is the API, and is there an OpenAPI specification?
It is a standard REST/JSON API over HTTPS with bearer-token authentication. There is a full OpenAPI 3.1 specification at https://meteofeed.com/openapi/v1.yaml, interactive reference documentation at https://meteofeed.com/docs, and a downloadable Postman collection at https://meteofeed.com/postman-collection.json.
What are the rate limits and quotas?
Each tier has a monthly request quota plus a 60-requests-per-minute-per-key burst limit. Every response carries standard X-RateLimit-* and X-Quota-* headers (and a Retry-After header on a 429 response) so clients can self-throttle. Quotas reset monthly.
Does MeteoFeed provide historical weather data and climate normals?
Yes. Climate normals (/v1/climate) and a deep historical archive (/v1/historical) are available worldwide via NOAA GHCN-Daily, with much deeper national archives where we run native pipelines: the Netherlands back to 1970, Germany to 1781, Belgium to 1952. There is also a day-ahead forecast archive (/v1/historical/forecast) showing what the model predicted for a past date.
Does MeteoFeed have weather radar and satellite imagery?
Yes. Ground precipitation radar comes from KNMI, DWD RADOLAN and the EUMETNET OPERA composite across about 29 European countries; everywhere else uses NASA GIBS satellite precipitation imagery. Radar is served as PNG tiles via /v1/radar. There is also a public live 3D cloud globe at https://meteofeed.com/globe.
Can I get severe-weather alerts or push notifications?
Yes. /v1/warnings returns active severe-weather warnings (KNMI, DWD and MeteoAlarm across 30+ European countries). For push delivery, register a webhook in the dashboard and MeteoFeed POSTs HMAC-signed JSON whenever a new event appears — a severe-weather warning for a region, an earthquake near a point, a tropical-cyclone change, a geomagnetic or aurora storm, a tsunami threat, or a volcano alert change.
Is the weather data free to access without an API key?
No. The weather data is served behind a bearer key (a free tier plus paid tiers). The documentation, the OpenAPI specification, the coverage details and the marketing site are fully public, but live data requires an authenticated key so usage can be metered fairly.
How is MeteoFeed different from other weather APIs?
Three things. Breadth: one bearer token covers 221 countries and territories and roughly eighteen data domains, instead of stitching together per-country or per-domain providers. Model choice: you can pin or compare 11 named forecast models via ?model= rather than being locked to a single provider. Depth: multi-decade national archives, commercial-clean sourcing, and HMAC-signed push webhooks. It is a consolidated alternative to single-country or single-domain weather APIs.
Does MeteoFeed cover marine, air-quality, solar and aurora data?
Yes. Marine: wave forecasts across European and global sea crops, plus daily global sea-surface temperature with a marine-heatwave anomaly (/v1/marine). Air quality and pollen: Copernicus CAMS with a European AQI (/v1/air-quality, /v1/pollen). Solar: sun position, UV index and a photovoltaic-yield stack (/v1/sun, /v1/uv, /v1/solar). Aurora and space weather: the NOAA OVATION aurora-visibility forecast plus the Kp index and geomagnetic-storm scales (/v1/aurora, /v1/space-weather).
