1. Uses only official public data.All live prices are scraped directly from official public pages or open APIs of each platform—no login-required, cracked, or third-party-sourced data is used.
2. Clearly state if outdated.If a platform’s data hasn’t refreshed in over 7 days, its row automatically displays a yellow ‘Reference price · To be verified’ label and is excluded from price-drop alerts (to prevent false alerts based on stale pricing). A green ‘Live’ label indicates the official website’s current real-time price.
3. No unauthorized credit card charges.GPUs with different VRAM capacities or chip variants (e.g., 4090D, modified 4090 48G, A100 40G) are never grouped under the same model name in pricing.
4. Abnormal prices are excluded from rankings.Prices deviating >40% from the 7-day average per platform are flagged as pending verification and excluded from price-comparison recommendations.
5. All conversions clearly stated.All quotes involving currency conversion (USD×7.2) or daily-to-hourly conversion (÷24) must explicitly state original pricing and calculation method in the billing description.
6. Prices are subject to the order page.Pricing changes constantly; our data may lag behind platforms’ second-level updates—always verify final pricing on the platform’s checkout page before payment.
