Support
One address for everything: account, API keys, the MCP server, billing, data questions and privacy requests.
What to include
- Your account email — the one you signed up or bound a key with.
- For a payment problem, the email you used at Stripe checkout as well. It is often different from your DC Hub login, and that mismatch is usually the cause.
- What you were doing — the page URL, or for the API/MCP server the endpoint or tool name and the arguments you sent.
- What happened — the exact error text or HTTP status, and roughly when (with your time zone).
- Which client for MCP issues — Claude, ChatGPT, Cursor, Claude Code, etc.
Please do not paste a full API key into an email.
Response
Email replies are typically same day. Refund requests follow the timeline in the refund policy.
