How to fix HTTP Error 503: Service Unavailable error - bottlenose

Question

Executing the command:
amazon = bottlenose.Amazon(AMAZON_ACCESS_KEY,AMAZON_SECRET_KEY,AMAZON_ASSOC_TAG)
response = amazon.ItemLookup(ItemId='B007OZNUCE')
I got the error:
Traceback (most recent call last):

Answer 1

Region is missing, add something like "DE" or "ES" depending on the country you're using.
Default is 'US':
amazon = bottlenose.Amazon(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_ASSOCIATE_TAG, Region='FR')
from: https://github.com/lionheart/bottlenose
Additionally: have you checked in the 'amazon' customer portal, on the 'platform API' access for the countries you want to use, that the API is enabled?
France: https://partenaires.amazon.fr/assoc_credentials/home
UK: https://affiliate-program.amazon.co.uk/assoc_credentials/home
US: https://affiliate-program.amazon.com/assoc_credentials/home
For me, it shows inactive, hence, that's probably the cause for the request to be denied.

Thanks for the inputs!
The same code worked magically now. Seems the api keys weren't enabled immediately after creating them.
