I am planning to create an API, wherein the user will send input, which would be processed using the business logic at my backend and output transmitted back.
I plan to market it as API-as-a-Product. I understand RapidAPI is the best marketplace, however they charge 20% on every sales.
Is there any other way to put the API to users with lesser platform fees?
Will AWS Lambda + API Gateway be a full substitute for RapidAPI? Thanks in advance.
I think you mixing what RapidAPI and what AWS Lambda is, one is market place the other hosting service. if you going to sell API's you will need to have your own website to sell them, the markets are just one of the things to do when popularizing your service
100% correct
I personally think you should built your own stack to do this using a light weight stack to do this. Probably cheaper in the long run and easier to scale in my opinion
