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 · ★ 73
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.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
