## FAQ

### Do I need a trend-index (巨量算数) account?

No. You need one SocialToAI key, or sign-in from your AI client; nothing is read in an account of yours.

### Can the data be exported?

Every call returns JSON, so the numbers go straight into a sheet, a report or your AI's answer.

### How much does it cost?

From 2 credits a call ($0.0067 at the first pack); failed calls are free. 100 free credits on sign-up, no card.

### Can Claude or ChatGPT read it?

Yes, once SocialToAI is connected over MCP: ask for a keyword's trend or a brand against its industry and it makes the calls.
