RestGPT

Overview

RestGPT is an autonomous agent that bridges large language models with real-world applications through RESTful APIs. It enables AI systems to interact with external services like movie databases, music players, and other web applications without manual API integration. The tool uses an innovative iterative coarse-to-fine planning framework that breaks down complex tasks into manageable sub-tasks, then executes them through API calls. The system consists of several key modules: a Planner that generates natural language sub-tasks, an API Selector that maps high-level goals to specific API calls, and an Executor with a Caller for organizing API parameters and a Parser for processing responses. This architecture allows RestGPT to handle multi-step workflows that require sequential API interactions. RestGPT addresses the challenge of making LLMs actionable in real-world scenarios by providing a structured approach to API interaction. It comes with RestBench, a comprehensive evaluation benchmark featuring scenarios from TMDB movie database and Spotify, with human-annotated solution paths for testing agent performance. The tool demonstrates practical applications in information retrieval and content management tasks, showing how AI agents can autonomously navigate complex API ecosystems to accomplish user goals.

Use Cases

• • Building AI assistants that autonomously search and retrieve information from movie databases
• • Creating music playlist management bots that interact with streaming services like Spotify
• • Developing agents for complex multi-step data retrieval tasks across multiple APIs
