What is a Function Calling API?
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.
Frequently Asked Questions
How does a function calling API enhance LLM capabilities?
It allows models to invoke code or access external resources, bridging the gap between reasoning and real-world action.
What are typical uses of function calling APIs in AI?
They enable dynamic integration with search, databases, code interpreters, and external plugins during chat or workflow execution.
