last night I only got 401 errors after the same script working fine an hour before. I checked the "downed services site" and all seemed well. I almost tore up the whole project looking for the flaw when I thought to myself: "self, just give it a night and maybe it's an undocumented flaw on the API". Well, this morning it works again.

I found the "# of API calls" report once... now I can't find it anymore. I'm sure it's there and will stumble across it again sometime and then forget. I do wish somebody would document the WeatherKit API in a professional manner. It seems very much "institutional knowledge" at best, trial and error in the worst. Maybe Ajax can get on that as it's first task :D.

I don't think Apple uses kph for precipitation intensity, at least not currently / anymore. I ran a 240h hourly API request and the precipitation amount ranges from 0 to 1.9. The precipitation intensity is identical to the precipitation amount. Since it's hourly granularity, the unit of speed is definitely not "per second" so not m/s. also K/h is implausible because 1.9 kph = 75000 inches per hour. I would venture to guess that precipitation is "cm" and precipitation intensity is "cm/h" Has anyone found explicit confirmation of the units? I don't see it anywhere in Apple's documentation. cloudCover: % daylight: T/F humidity: % precipitationAmount: cm ? precipitationIntensity: cm/h ? precipitationChance:% pressure: hPa ? snowfallIntensity: cm/h snowfallAmount: cm temperature: C temperatureApparent: C temperatureDewPoint: C uvIndex: 0-10? visibility: m? windDirection: degrees ? windGust: m/s ? windSpeed: m/s ?

this works for me. note that you need to update with your token: curl -v -H "Authorization: Bearer {YOUR_TOKEN_HERE}" "https://weatherkit.apple.com/api/v1/weather/en/35.0/-80.0?dataSets=forecastHourly&currentAsOf=2022-01-01T00:00:00Z&hourlyStart=2022-01-01T00:00:00Z&hourlyEnd=2022-01-07T00:00:00Z&timezone=America/New_York&countryCode=US" the token can be created with python: import jwt import datetime TEAM_ID = 'TTTTTTTTTT' #replace with your team_id from the apple developers site, keep in quotes KEY_ID = 'KKKKKKKKKK' #replace with key_id from the apple developers site APP_ID = 'com.MyVeryOwnURL.WetterAPI' #invent this with your own domain in reverse file_path = f'./AuthKey_{KEY_ID}.pem' # use full path to the key you download from Apple Developer Site. Note, I converted my .p8 file to .pem using `openssl pkcs8 -nocrypt -in AuthKey_KKKKKKKKKK.p8 -out AuthKey_KKKKKKKKKK.pem` header = { "alg": "ES256", "kid": KEY_ID, "id": f"{TEAM_ID}.{APP_ID}" } current_time = datetime.datetime.utcnow() expiration_time = current_time + datetime.timedelta(minutes=19) payload = { "iss": TEAM_ID, "iat": int(current_time.timestamp()), "exp": int(expiration_time.timestamp()), "sub": APP_ID } with open(file_path, 'r') as file: private_key = file.read() coordinates= '35.0,-80.0' token = jwt.encode(payload, private_key, algorithm='ES256', headers=header) # Create the curl command curl_command = f'curl -v -H "Authorization: Bearer {token}" "https://weatherkit.apple.com/api/v1/weather/en/35.0/-80.0?dataSets=forecastHourly&currentAsOf=2022-01-01T00:00:00Z&hourlyStart=2022-01-01T00:00:00Z&hourlyEnd=2022-01-07T00:00:00Z&timezone=America/New_York&countryCode=US" print(curl_command) After that's done, run it in the terminal. it'll give you your the line you need to copy and explicitly paste to execute on the terminal. good luck!

I don't have an answer but I'm experiencing the same frustration. I'm trying to use python to generate my JWT then generate a curl command to test in the terminal (because it has verbose messaging). I created a private key. under "Keys" create a key with the + button. this generates a file AuthKey_{KEY_ID}.p8 where {KEY_ID} is the key_id that was given. I downloaded the p8 file. I converted the p8 file to .pem using openssl pkcs8 -nocrypt -in AuthKey_{KEY_ID}.p8 -out AuthKey_{KEY_ID}.pem I've seen different instructions regarding the creation of the identifier. the documentation says create a ServiceID. an 'influencer' I've tried to follow says to create an App ID identifier. I tried both but have questions: 1) if serviceID do I need to enable "Sign in with Apple". I did not. 2) If AppID, a) which appID Prefix do I choose? I chose the one associated with TeamID, although that was not the default. b) do I tick the box for WeatherKit under the Capabilities or App Services sub-tab? it offers both. I chose both. 3) I created a JWT using python. I have understood that the one 'key' is to get the header to include the APP_ID (the reverse URL). here's what I'm trying but it still fails: ## note remember to update the file path of the .pem file to reflect your username and file location import jwt import datetime TEAM_ID = 'NONYABIZN5' KEY_ID = '4WHTVRUWNT' APP_ID = 'com.beispiel.WetterAPI' file_path = f'/Users/myUser/sandbox/wetterapi/AuthKey_{KEY_ID}.pem' header = { "alg": "ES256", "kid": KEY_ID, "id": f"{TEAM_ID}.{APP_ID}" } current_time = datetime.datetime.utcnow() expiration_time = current_time + datetime.timedelta(minutes=19) payload = { "iss": TEAM_ID, "iat": int(current_time.timestamp()), "exp": int(expiration_time.timestamp()), "sub": APP_ID } with open(file_path, 'r') as file: private_key = file.read() token = jwt.encode(payload, private_key, algorithm='ES256', headers=header) # Create the curl command curl_command = f'curl -v -H "Authorization: Bearer {token}" "https://weatherkit.apple.com/api/v1/availability/37.323/122.032?country=US"' print(curl_command) that produces a curl command that I can drop into my terminal. the curl returns: * Connected to weatherkit.apple.com (2600:1408:c400:58::17d5:9e54) port 443 (#0) * ALPN: offers h2,http/1.1 * (304) (OUT), TLS handshake, Client hello (1): * CAfile: /etc/ssl/cert.pem * CApath: none * (304) (IN), TLS handshake, Server hello (2): * (304) (IN), TLS handshake, Unknown (8): * (304) (IN), TLS handshake, Certificate (11): * (304) (IN), TLS handshake, CERT verify (15): * (304) (IN), TLS handshake, Finished (20): * (304) (OUT), TLS handshake, Finished (20): * SSL connection using TLSv1.3 / AEAD-CHACHA20-POLY1305-SHA256 * ALPN: server accepted http/1.1 * Server certificate: * subject: CN=weather-data.apple.com; O=Apple Inc.; ST=California; C=US * start date: Jul 25 21:03:10 2023 GMT * expire date: Oct 23 21:13:10 2023 GMT * subjectAltName: host "weatherkit.apple.com" matched cert's "weatherkit.apple.com" * issuer: CN=Apple IST CA 8 - G1; OU=Certification Authority; O=Apple Inc.; C=US * SSL certificate verify ok. * using HTTP/1.1 > GET /api/v1/availability/37.323/122.032?country=US HTTP/1.1 > Host: weatherkit.apple.com > User-Agent: curl/8.1.2 > Accept: */* > Authorization: Bearer sdfsfns,dfnanflsandfasdanflknasdlknalsdknlnlnasflnldsfknalasdfknlksandflnsdflnasdflnsaldfknsldakfnlskndflsknadflnsadflnsaldfnaoiw,vm,asfdlkjsdlfklnvlnasdjfsdfadnflsakfndklsfdalknklfsdnlklrewoewu8llnsLSKNlkzxcLKlKNlnskdKVLKSNlknZLKcnLKLKAlkaMLnSDVBisdbdkvbkjvsavskajdbzCXk-2-TasdE-skdfjKJHkjKLlkJLKJlkNLnLKHHiUbKBNhIUHIU > < HTTP/1.1 401 Unauthorized < Server: Apple < X-Frame-Options: SAMEORIGIN < Strict-Transport-Security: max-age=31536000; includeSubdomains < X-XSS-Protection: 1; mode=block < Access-Control-Allow-Origin: * < X-Content-Type-Options: nosniff < Content-Security-Policy: default-src 'self'; < X-REQUEST-ID: 8e5e48ac-410a-4398-b7e6-8d4fbd0454a4 < Date: Thu, 17 Aug 2023 01:56:37 GMT < X-Cache: TCP_MISS from a23-202-158-148.deploy.akamaitechnologies.com (AkamaiGHost/11.2.2-50400341) (-) < Connection: close < * Closing connection 0 {"reason": "NOT_ENABLED"}% I've tried this with both "Identifiers" by choosing a suffix to my Reverse URL and using that in one and not using that in the other...
