I'm setting up a new pod in my pod file and when I do pod install I have an error what should I doing ?

I tried this line to add the pod in my podfile : 

pod 'MapboxVisionNativeAll', :podspec => '<https://api.mapbox.com/downloads/v1/vision/ios/mapbox-vision-native-all/0.3.0.podspec?access_token=>'

this the error 

[!] Failed to fetch podspec for `MapboxVisionNativeAll` at `https://api.mapbox.com/downloads/v1/vision/ios/mapbox-vision-native-all/0.3.0.podspec?access_token=<sk.eyJ1IjoiYnJhaGltY2hlYmJpIiwiYSI6ImNqdXlhMXl6aDBmeXo0M3BpYjV6MnFib3IifQ.VinI6ER1YN2nDxXRJzaFXw>`.
