Defining application programming interfaces (APIS) using object schemas

A system, comprising:

• a processor;
• and
• memory storing instructions which, when executed on the processor, perform an operation for accessing data using dynamically generated application programming interface (API) calls, the operation comprising:
• receiving a data request from a client device, the data request identifying an navigable path through a graph projection of the API, the navigable path including a plurality of nodes;
• generating an API call to process the data request, wherein the generating comprises, for each node in the navigable path:
• identifying a node in the graph projection to access data from, and generating a subquery to access data from the node using one or more parameters included in the data request and defined in a schema associated with the node;
• executing the one or more subqueries to obtain a result;
• and returning the result of executing the subqueries as the result of the API call;
• wherein the operations further comprise:
• verifying that the identified node associated with the subquery references an immediate parent node of the node and that the subquery comprises a valid query based on a schema associated with the node in the graph projection of the API.

A non-transitory computer-readable medium comprising instructions which, when executed by one or more processors, performs an operation for accessing data using dynamically generated application programming interface (API) calls, the operation comprising:

• receiving a data request from a client device, the data request identifying a navigable path through a graph projection of the API, the navigable path including a plurality of nodes;
• generating an API call to process the data request, wherein the generating comprises, for each node in the navigable path:
• identifying a node in the graph projection to access data from, and generating a subquery to access data from the node using one or more parameters included in the data request and defined in a schema associated with the node;
• executing the one or more subqueries to obtain a result;
• and returning the result of executing the subqueries as the result of the API call;
• wherein the operations further comprise:
• verifying that the identified node associated with the subquery references an immediate parent node of the node and that the subquery comprises a valid query based on a schema associated with the node in the graph projection of the API.
