We're building the API to become the primary layer of the product rather than an afterthought. We believe that going forward, people want to work with Buffer through many interfaces: MCP, CLI, our official apps, and 3rd party apps. Our launch today is a major commitment to this direction.

When we chose to invest in a platform 1.5 years ago, we knew we wanted to get it right. We use the same GraphQL API to power our web and mobile apps, so you'll get the reliability benefits of our testing, monitoring, partner relations, and infrastructure, which already handles significant scale.

The Buffer API is available on all plans, including free, and includes MCP and a CLI. It's easy to get started, just head to your account (or create one for free) and go to API in your settings. You can create a personal token or OAuth app right away and make your first API call instantly.
