One click, no email to start. The key works in ChatGPT's MCP config right away. Without an email it gets 10 free calls. Bind an email (free, no card) and the same key keeps working, at 50 requests/day for the rest of its 7-day trial. Free calls are counted per network: if this one has already used them, a new key needs the email from its first call.
Connector URL: https://dchub.cloud/mcp?apiKey={{TRIAL_KEY}}
ChatGPT has no header field, so the key rides in the URL.
In ChatGPT: Settings -> Connectors -> Add custom connector -> paste the URL.
After saving, restart ChatGPT and DC Hub will appear in the MCP connector list.
↻ Come back tomorrow: same key, new chat. The key lives in the connector URL, so every new ChatGPT chat already has DC Hub. Once an email is bound to it, the key keeps working past its free calls.
Without an email, a trial key gets 10 free calls. Bind an email and the same key keeps working, at 50 requests/day for the rest of its 7-day trial. Need more? Agents buy one of two things: $10 one-time = 1,000 API credits on this key (credits don't expire, no subscription), or Developer $49/mo for 500 MCP calls/day on every tool except the Pro-only ones. Pro ($99/mo) is for a human screening sites: all plans.
