Hello, @contact2ranjeet . Community Manager here. Thank you for posting your question here in the Marqeta Dev Community. Glad to have you join us.
Marqeta does not charge for API calls. However, we typically need to get more information about the project and the scope of services needed from us to be able to provide pricing. If you would like to explore using Marqeta's platform, we would be happy to connect you with a member of our Business Development team.
