Estoy usando la API de precios de AWS boto3 para obtener los precios de las instancias.

Pero no obtengo los resultados de la combinación (us west 2, r3.2x large, Linux, sin software pre instalado, tenencia = compartido)

Aquí está mi código:

pricing = boto3.client('pricing', region_name='us-east-1')
hourlyTermCode = 'JRTCKXETXF'
rateCode = '6YS6EN2CT7'
token = ''
while True:
    paginator = pricing.get_paginator('get_products')
    pages = paginator.paginate(
        ServiceCode='AmazonEC2',
        Filters=[
            {'Type': 'TERM_MATCH', 'Field': 'operatingSystem', 'Value': 'Linux'},
            {'Type': 'TERM_MATCH', 'Field': 'location', 'Value': 'US West (Oregon)'}

        ],

        PaginationConfig={
            'StartingToken':token
        }
    )

    for response in pages:
        for price in response['PriceList']:
            resp = json.loads(price)
            product = resp['product']  # ['attributes']['']
            sku = product['sku']

            if product['productFamily'] == 'Compute Instance':
                if str(product['attributes']['instanceType']) == str(amazon_instance_type) :
                    if str(product['attributes']['operatingSystem']) == 'Linux':
                        if str(product['attributes']['preInstalledSw']) == 'NA':
                            if str(product['attributes']['tenancy']) == 'Shared':
                                sku_key = resp['terms']['OnDemand'].get(sku)
                                if sku_key:
                                    price = sku_key[sku + '.' + hourlyTermCode + '.' + rateCode]['pricePerUnit']['USD']
                                    print 'here 7'
                                    print price

        try:
            token = response['NextToken']
        except KeyError:
            pass
