x402 AI Starter
Vercel Labs' reference Next.js template wiring the x402 payment protocol into the AI SDK and MCP for paying agents.
Last commit Dec 11, 2025 · ★ 74
Overview
x402 AI Starter is Vercel Labs' fullstack template demonstrating x402 — an HTTP-based accountless payment protocol — combined with the Vercel AI SDK, AI Gateway, and Coinbase CDP wallets. It shows a paying agent, a monetized remote MCP server, and paywalled APIs/pages, testable on Base Sepolia before moving to mainnet. The repository was archived (read-only) in June 2026, so treat it as a frozen reference rather than an actively updated template.
