## What it is
uAgents is a lightweight Python framework by Fetch.ai for building autonomous AI agents as microservices, using decorators for scheduled tasks, message handlers, and REST endpoints. Agents register on the Almanac smart contract for decentralized discovery and exchange cryptographically secured messages, optionally transacting on the Fetch.ai blockchain.

## Use cases
- build autonomous ai agents in python
- create a multi-agent system that communicates securely
- deploy agents as microservices with scheduled tasks
- register and discover agents on a decentralized network
- connect llm-powered agents to a marketplace
- run agent-to-agent messaging between services
- integrate blockchain wallets and transactions into agents

## When to choose
- you want a lightweight, decorator-based Python framework for autonomous agents
- you need decentralized agent discovery and secure inter-agent messaging
- you want agents that can transact on the Fetch.ai blockchain or integrate with Agentverse

## When to avoid
- you need a fully self-contained agent stack with no blockchain or external registry dependencies
- you require Python 3.14+ or legacy Python 3.8/3.9 support
- you want a framework with a large plugin ecosystem independent of the Fetch.ai platform
