A server retrieves source code comprising API calls from source code repositories, and parses the source code to identify a first set of APIs, each having one or more attributes. The server retrieves API definitions and parses the API definitions to identify a second set of APIs, each having one or more attributes. The server compares the first set of APIs and the second set of APIs to determine matching APIs. Using the matching APIs, the server detects backend systems associated with each API and generates a call graph for each API by traversing abstract syntax trees (ASTs) associated with the source code. The server builds an API model object for each API, comprising the attributes of the API, the detected backend systems, and the call graph.
