Methods, systems, and computer program products for user-initiated dynamic data application programming interface creation are provided herein. A computer-implemented method includes automatically transforming a user-provided query into one or more parameterized queries, generating a data application programming interface based on at least one of the parameterized queries, outputting the generated data application programming interface to the user providing the user-provided query, and storing the generated data application programming interface in a database accessible to one or more additional users.
