REST API for integrations

Programmatic access to Social0 — the interface the MCP server and custom integrations use.

Overview

The Social0 REST API at https://api.social0.app/v1 is the underlying interface for the MCP server, scripts, and custom apps. Authenticate with Authorization: Bearer sk_live_….

Higher-level option: If you use Claude, Cursor, or ChatGPT, start with the MCP Server instead of calling REST directly.
