aixyz

aixyz is a payment-native SDK for AI agents. It is aimed at developers who want to build agents and tools with a favorite framework and have payments handled through web3 payment rails, without manual payment integration work. Every agent deployed with it comes with x402 payments embedded, and calls to the agent settle on-chain automatically when another agent or user interacts with it.

The workflow described for the SDK is simple: build an agent, set a price, deploy, and start earning. Price setting is done by exporting an accepts object, which gates endpoints with instant micropayments. The documentation shows an example accepts configuration with an exact scheme and a $0.01 price. aixyz also auto-generates a server that exposes a well-known agent discovery card, a JSON-RPC endpoint with an x402 payment gate, and an /mcp endpoint for tool sharing with MCP clients. The documentation also lists A2A Protocol, MCP Protocol, x402 Payments, and ERC-8004 Identity among its protocol-related topics.

For agent development, aixyz supports Vercel AI SDK ai@^6 or any other framework for creating agents with tools. It includes templates, and the quick start says a new agent can be created with bunx create-aixyz-app my-agent, then run with bun run dev. The quick start states that the agent is running at http://localhost:3000 with payments, A2A, and MCP out of the box. The deployment options listed are Vercel, Docker, or standalone. The documentation index also mentions installation, project structure, testing, CLI, configuration, environment variables, file-system layout, and pages for aixyz/accepts, aixyz/config, aixyz/app, aixyz/model/fake, IndexPagePlugin, SessionPlugin, and experimental_StripePaymentIntentPlugin.

The page presents aixyz as documentation for an SDK rather than a hosted app. It points to GitHub and npm, and it is documented on Mintlify.
