Has anyone figured out the correct incantation of request parameters to get historic hourly weather conditions from WeatherKit? I've tried every combo of hourlyStart, dailyStart, currentAsOf, etc with past dates and it seems like the oldest it will go back to is midnight for today. I would like to get the last 24 hours of conditions.

We are currently using the DarkSky API for energy forecasting, and one important piece of data is the solar DNI. With DarkSky we could set the solar parameter to true and we would get this data: "solar": { "azimuth": 275, "altitude": 30, "dni": 677.1, "ghi": 369.1, "dhi": 33.6, "etr": 1318.8 } The WeatherKit API does not appear to have this parameter. Does anyone know if it will have this solar data eventually? It will impact whether we can use the API or not.

Hi all, I am trying to use the WeatherKit REST API but when I try to register an app, I don't see WeatherKit as an available services that I can select under the App Services Tab. How do I get access to the WeatherKit service? Thanks,

If you use the iOS16 Swift WeatherKit API you can get the weather data attribution logo doing something like: // Skipping full syntax for example let attribution = WeatherService.shared.attribution // A URL to an image you can show along with the weather data attribution.combinedMarkLightURL What about if you are not using the iOS16 WeatherKit wrappers e.g. you are using the REST API on your own server to return data. The API docs show a providerLogo/providerName parameter in the metadata returned from the service, but they don't seem to be populated right now. Is it ok just to use a unicode Apple logo to make a string instead like:  Weather Also in the API there is a metadata object returned in each dataset e.g. current, daily, hourly which each has an attributionURL field, will all those values always be the same or we might have to display multiple URLs for data sources, the Swift example seems to just have one attribution object.

I have upgraded from macOS 12.5.4 to macOS 13 Beta 1. Haven't done anything odd. I am attempting to use WeatherKit but I am getting a lot of (odd) errors: The sample can't access the ~/Library/Weather/ folder despite it being set to read for users, others and group. (I've since switched to read and write for all, but no dice). Lots of other odd errors. 2022-06-11 22:52:26.720487+0100 PlayWithWeatherKit[16282:277975] [WeatherService] Couldn't get access to the /Library/Weather directory for the geocode Store. error=Error Domain=NSCocoaErrorDomain Code=257 "The file “Weather” couldn’t be opened because you don’t have permission to view it."

In the Meet WeatherKit video it is stated that "You can access historical data by specifying a start and end date to the hourly and daily requests.", but I'm not seeing a way to do that in the Swift API (I see it is there in the REST API). Am I missing something or is that just not implemented yet?

Could someone help me find the example code for WeatherKit that is associated with the video? Thanks.

Hi, I am getting and invalidJWTResponse when using WeatherKit Swift API, I have setup everything correctly including enabling WeatherKit in both Capabilities and App Services, Added WeatherKit" to Xcode Capabilities, and waited for more than one day! But still it's not working! invalidJWTResponse(Optional(<NSHTTPURLResponse: 0x6000008d8300> { URL: https://weather-data.apple.com/v2/token } { Status Code: 401, Headers {     Connection =     (         close     );     "Content-Length" =     (         0     );     Date =     (         "Thu, 09 Jun 2022 18:24:24 GMT"     );     Server =     (         "AppleHttpServer/5712591c84160e0cbbf19c8f434c32ab02f2a7f4"     );     "Strict-Transport-Security" =     (         "max-age=31536000"     );     "X-Apple-Origin" =     (         "01ca7adc-14e8-31f5-9654-4375b40868e2"     );     "X-B3-TraceId" =     (         795fbfea426330d9     );     "X-Cache" =     (         "TCP_MISS from a88-221-161-85.deploy.akamaitechnologies.com (AkamaiGHost/10.8.2-41841244) (-)"     );     "X-REQUEST-ID" =     (         "3e6d21c8-ffa0-4c56-aa91-8466619a4993"     ); } }))

The documentation lists the number of calls per month you can make for the different pricing tiers here: https://developer.apple.com/weatherkit/get-started/ but are there going to be any per second/minute/hour rate limits on calls to the API like with other weather service APIs. For example maybe you get 1,000,000 calls per month but there is some limit like 5 calls per second or 10,000 calls per hour imposed by the APIs? Also what happens if you go over your allowed call limit for the month, will the API just return an error like HTTP 402 or you will get a warning for a period of time? Would you be able to buy extra calls for the month without having to upgrade to a new tier, assuming maybe you are experiencing a temporary increase in traffic.

To anyone it may help, I've put together an OpenAPI spec of the WeatherKit REST API, which you may find useful for client generation using one of the OpenAPI generators. https://github.com/vanshg/WeatherKit-OpenAPI

Hi - I don't see anything in the documentation about which regions of the world the API will support e.g. US, Europe. I see there is an /api/v1/availability you can call but is there some rough guidelines around what areas are supported and which aren't. Thanks Mark.

Hi there! Please could you publish some of the specifics for authentication for the new WeatherKit REST API? I am attempting to use something cobbled together from MapKit, and unfortunately WeatherKit returns a 500 error in response. Broken code sample below. If you find a working solution or can identify an error, please comment with the solution. Thank you! require 'http' require 'jwt' require 'openssl' require 'logger' p8 = OpenSSL::PKey::EC.new(File.read("/PATH/TO/DOWNLOADED/P8/FILE")) token = JWT.encode({ iss: 'KEY_NAME_FROM_CIP', iat: Time.now.to_i, exp: Time.now.to_i + 3600, aud: 'weatherkit', }, p8, 'ES256', { kid: 'KEY_ID_FROM_CIP', typ: 'JWT' }) res = HTTP.use(logging: { logger: Logger.new(STDOUT) }).headers( "Authorization" => "Bearer #{token}" ).get "https://weatherkit.apple.com/api/v1/weather/en/LONG/LAT?dataSets=currentWeather&timezone=Europe/London" puts "code: #{res.code}" puts res.body
