This covers the Vercel Marketplace integration system: discovering third-party services through the CLI, installing them with `vercel integration add`, and letting Vercel auto-provision environment variables so you don't manually juggle credentials. It handles the one-click setup flow for databases like Neon, auth providers like Clerk, and monitoring tools like Datadog, plus the unified billing model where everything shows up on one invoice. The guidance includes the integration build path if you're publishing your own service to the marketplace. Worth noting the 1–3 minute provisioning delay after installing database integrations, which trips people up when connection strings aren't instantly live. Chains out to auth and storage skills when it detects provider-specific patterns in your code.
