Frequently asked questions
Can I cancel anytime?
Yes. Cancellations take effect at the end of your current billing cycle — no clawbacks, no questions.
Do I need a Steam API key?
No. We use Steam OpenID for read-only profile access. Your account credentials stay with Valve.
How accurate is the pricing?
Within ±8% of Buff163 closing prices on 80% of historical sales for items with tracked float / pattern tiers.
Do you store my inventory?
Cached for 10 minutes for performance. You can clear it from Settings any time, and we never list or trade your items.
Which marketplaces are covered?
Steam Community Market, Buff163, CSFloat, DMarket, and Skinport on Pro and Premium plans.
What happens when I downgrade?
Your watchlist shrinks to the new plan's cap, but inventory and pricing data stay visible (read-only).
