First, install the necessary dependencies for your agentic system
You'll need swarms, fastapi, and the x402 package for the server.

Environment Configuration:
Create a .env file in your project root with the required API keys.
You'll need:
> Keys for your LLM
> Your exa search api key for search features
> Your wallet address and other envs from coinbase

Core Implementation:
Initialize your FastAPI application and configure the Swarms agent with specific capabilities.
This example creates a research agent with access to the Exa search tool for comprehensive information gathering.

Payment Middleware Configuration:
The x402 middleware wraps your endpoint with payment verification.
Configure the price, recipient wallet address, blockchain network, and request/response schemas.
This middleware intercepts requests and validates payment before execution.

Endpoint Implementation:
Define your paid endpoint with standard FastAPI decorators.
The payment middleware handles all payment verification transparently.
Your endpoint logic remains clean and focused on business functionality.

Key Architecture Benefits:
> x402 eliminates payment gateway integration complexity while enabling true micropayments.
> The middleware pattern keeps payment logic separate from business logic.
> Cryptocurrency payments provide global accessibility without traditional payment processing overhead.
> This architecture scales from prototype to production with minimal modification.

Conclusion
x402 represents a paradigm shift in API monetization by eliminating the complexity of traditional payment processors while enabling true micropayments that were previously economically unviable.
With just a few lines of middleware configuration, you can transform your AI agents into revenue-generating assets without merchant accounts, PCI compliance, or payment gateway contracts.
The combination of Swarms for agent orchestration, FastAPI for robust infrastructure, and x402 for frictionless cryptocurrency payments creates a complete production-ready stack for commercial agent deployment.
Start building monetized agent services today by replacing the wallet address with your own, deploying your server, and immediately accepting for your agents.
The future of agent commerce is permissionless, accessible to every developer, and available right now.
