An interface that allows LLMs or agents to trigger external functions, APIs, or tools programmatically during reasoning.
More about Function Calling API
Function Calling API is an interface that enables LLMs or agents to trigger external code, APIs, or tool executions based on natural language instructions or workflow needs. This is a key feature in modern tool-augmented LLM architectures such as Toolformer, tool integration, and LLM orchestration.
Function calling APIs make it possible for agents to go beyond text generation, directly interacting with real-world systems to fetch data, perform actions, or automate tasks.
