How much does one call return?
One call returns one object, with no pages, for 24 credits.
Is there a rate limit?
5 calls a second per key, 20 a second after your first purchase. A request over the limit is told how long to wait and is not charged.
How do I use it from Claude, ChatGPT or Cursor?
Yes. In Claude or ChatGPT, add the MCP address https://mcp.socialtoai.com/mcp as a custom connector, sign in with the code we email you and press Allow; there is no key to paste. In Claude Code, run one command, type /mcp, pick socialtoai and sign in; Codex and Cursor sign in too, with their steps on the connect page. Then ask in plain words and your AI calls call for you.
