PostPeer is a unified social media API that lets your app or AI agent handle publishing, scheduling, and engagement across multiple platforms using one integration. If you don’t want to build separate platform-by-platform workflows, PostPeer gives you a single place to connect accounts and read back what happened.
It’s a fit for developers building social features into a SaaS product, agencies managing multiple accounts, and AI agents that need consistent “tools” for social actions.
A key difference is how it fits both traditional code and AI agents. You can use the REST API for your own agent loop or backend, or connect PostPeer through an MCP server so actions show up as typed tools your agent can call. There are also agent skills meant to provide the right request shapes and workflows for publishing and engagement.
PostPeer supports partial results per post (you get status per platform rather than an all-or-nothing outcome). It also offers a free trial with 20 credits and no credit card required, so you can test the workflow before committing.
