Frequently Asked Questions

A social media API for AI agents provides programmatic access to social platforms so AI agents can create, schedule, and manage posts autonomously. The best APIs are designed for agentic workflows — not just posting, but full social media operations including analytics and inbox management.

It depends on your AI client. MCP works natively with Claude Desktop, Cursor, and other MCP-compatible agents. REST API works with any HTTP client, automation platform (n8n, Zapier, Make), or custom agent. Some platforms like Aidelly offer both.

Yes. A social media API gives your custom AI agent the ability to post, schedule, and analyze content. With Aidelly, for example, you can build an agent that autonomously creates content, schedules it across 6 platforms, and reports on performance — all via API calls.
