One API, every platform

Supported Platforms

One Integration. Every Social Capability. Every Platform.

Give your app or AI agent one social media connection instead of building separate integrations for every platform and workflow.

One API. Every Way to Build.

Build directly with the API, connect PostPeer to your automation stack, or give your AI agents social media capabilities. Choose the way you work.

Give Your Agents Social Media Tools. An agent does not need another endpoint list. It needs tools it can call, accounts it can discover at runtime, and responses it can reason about. Select a connection method to see what your agent works with.

Agent Skills

Explore Agent Skills

Drop PostPeer workflows into supported coding agents so they get request shapes, field names, and error patterns up front.

02

MCP Server

Explore MCP Server

Point an MCP client at PostPeer and its social actions arrive as typed tools, with connected accounts looked up at runtime.

03

REST API

View API Docs

Running your own agent loop? Every action is a plain HTTP call with a predictable JSON response you can wire into function calling.
