SCOPE

What Pro covers

Pro licenses data that TANDIU compiles or produces itself:

Official LLM API list prices and their daily history, the TANDIU price index and recorded price changes
Cloud agent comparison, including TANDIU's own tests (identity stability, egress IP, cloud computer form)
Token budget per job role and the coding PC ladder

Not included in Pro and not licensed for resale: third-party benchmark scores (Artificial Analysis, LiveBench, Epoch AI), GPU market and rental prices, public procurement data and AI funding data. These stay free to view on the website with their original sources.

FAQ

Who can buy Pro? Businesses and individuals outside mainland China. Pro is a self-serve subscription delivered by API key; there is no consulting or custom work.

How do I get my key? Right after checkout you are taken to a page that shows your API key. Keep it secret; you can rotate it from the same link within 7 days, or email us later.

How do I cancel? Use the subscription link in your Paddle receipt email, or email contact@tandiu.cn. Your key keeps working until the end of the paid period.

Refunds? Full refund within 14 days of a payment, see the refund policy.

Will the free data change? No. Pages, open feeds and the anonymous MCP server stay free.
