This is pretty neat. If you could take it a step further and have integrations to send the response payloads to other services like S3, SES, SQL insert into Redshift, etc then it would be great.
You can easily do this with AWS Lambda and the boto3 library. You get logging, metrics and alerting if you want too. AWS has a generous free tier.
For python devs, this is a great framework to easily create and deploy them - https://github.com/aws/chalice.
