Fetch.ai’s Autonomous Economic Agents (AEA) Framework is an open-source Python SDK and CLI toolset for creating modular, autonomous agents that can negotiate, transact, and collaborate in decentralized environments. It includes scaffolding commands to generate agent projects, templates for protocols and skills, connection modules to integrate with multiple ledgers (Ethereum, Cosmos, etc.), contract interfaces, behavior and decision‐making components, testing and simulation utilities, and a publishing mechanism to distribute agents on the Open Economic Framework network. Developers leverage its modular architecture to rapidly prototype digital workers for DeFi trading, data marketplaces, IoT coordination, and supply chain automation.

Build with ADK streamlines the creation of AI agents by providing a CLI scaffolding tool, workflow definitions, LLM integration modules, testing utilities, logging, and deployment support. Developers can initialize agent projects, select AI models, configure prompts, connect external tools or APIs, run local tests, and push their agents to production or container platforms—all with simple commands. The modular architecture allows easy extension with plugins and supports multiple programming languages for maximum flexibility.
