AWS Pricing API not yielding prices for the given search criteria - python-2.7

Question

I am using AWS boto3 pricing api to get the prices of instances.
But I am not getting the results for the combination (us west 2, r3.2x large, Linux, No pre software installed, tenancy =shared)
Here is my code:
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

Answer 1

This works:
import json
import boto3
client = boto3.client('pricing', region_name='us-east-1')
response = client.get_products(
ServiceCode='AmazonEC2',
Filters=[
{'Type': 'TERM_MATCH', 'Field': 'operatingSystem', 'Value': 'Linux'},
{'Type': 'TERM_MATCH', 'Field': 'location', 'Value': 'US West (Oregon)'},
{'Type': 'TERM_MATCH', 'Field': 'instanceType', 'Value': 'r3.2xlarge'},
{'Type': 'TERM_MATCH', 'Field': 'tenancy', 'Value': 'Shared'},
{'Type': 'TERM_MATCH', 'Field': 'preInstalledSw', 'Value': 'NA'}
]
)
for pricelist_json in response['PriceList']:
pricelist = json.loads(pricelist_json)
product = pricelist['product']
if product['productFamily'] == 'Compute Instance':
print pricelist['terms']['OnDemand'].values()[0]['priceDimensions'].values()[0][u'pricePerUnit']['USD']
It is based on the output of:
