Getting Started
Automate your social posting with the Posteady REST API and MCP server.
Automate your social posting on Threads and X through two interfaces:
- REST API — authenticate with an API key. Best for scripts, servers, and your own automations.
- MCP server — authenticate with OAuth 2.1. Best for AI clients like Claude and Cursor.
Both require the Creator plan or above.
| REST API | MCP server | |
|---|---|---|
| Mechanism | API key | OAuth 2.1 |
| Credential | Authorization: Bearer pk_... | Access token (Bearer) |
| Best for | Scripts, servers, cron jobs | AI clients (Claude, Cursor) |
| Auth guide | REST authentication | MCP authentication |
Your first call
The fastest way to start is the REST API. Create an API key in your Posteady settings, then publish a post:
curl -X POST https://www.posteady.com/api/v1/posts \
-H "Authorization: Bearer pk_..." \
-H "Content-Type: application/json" \
-d '{
"accountIds": ["<account-uuid>"],
"posts": [{ "text": "Hello from the Posteady API" }]
}'You can fetch your connected account IDs from GET /v1/accounts.
