Frequently Asked Questions

What is FSZero?

FSZero is a trading platform for classic Roblox limited items. It provides algorithmic manipulation-free RAP valuations, a swipe-based trade feed that auto-generates trades from your inventory, item charts, portfolio tracking, and owner lookup.

Is FSZero free?

Yes. FSZero is currently free during early access. Paid tiers may be introduced in the future.

What does manipulation-free RAP mean?

RAP stands for Recent Average Price. Traditional RAP is distorted by two opposite kinds of manipulation: LLPs (sales priced far below an item's real value) and projecteds (sales priced far above an item's real value, usually by a coordinated group trying to pump the number). FSZero filters both out of the calculation. The displayed value, which we call manipulation-free RAP (MFRAP), reflects what the item is genuinely trading at, not what the loudest or most coordinated traders want it to look like. You can toggle filtering off, use a basic 50% threshold, or set a custom threshold in Advanced Mode.

What is an LLP?

An LLP (Low List Price) is when someone sells a valuable item far below its real market value, often by accident or to manipulate the displayed value downward. FSZero filters LLPs out of the RAP calculation by default.

What is a projected?

A projected is the opposite of an LLP: an item sold at an artificially inflated price, usually by a coordinated group trying to pump its displayed value. FSZero filters projecteds out of the RAP calculation by default.

How does FSZero filter out LLPs and projecteds?

FSZero first establishes a baseline value for the item, then looks at its most recent sales (20 by default) and compares each one to that baseline. A sale priced far below the baseline is treated as an LLP; a sale priced far above it is treated as a projected. Both are dropped before the value is computed. By default, sales more than 50% below the baseline are filtered out as LLPs and sales more than three times the baseline are filtered out as projecteds. The sales that survive are combined into a recency-weighted average, so more recent sales carry more weight. In Advanced Mode you can widen or narrow the sales window, adjust the filter threshold, or turn filtering off to see raw RAP.

Does FSZero support UGC limiteds?

No. FSZero is built exclusively for classic Roblox limiteds. UGC limiteds are not supported by design. They might be introduced in the future.

How does the trade feed work?

You connect your Roblox account using bio verification: enter your Roblox username and place a short generated code in your Roblox profile bio. FSZero confirms ownership and then reads your public Roblox inventory and cross-references it with other connected users' inventories. The system auto-generates fully proposed trades that fit within both users' tolerance settings, then shows them to you as swipeable cards. Swipe right to indicate interest. If both users swipe right on the same trade, it becomes a mutual match with priority chat access.

Is my Roblox account safe to connect?

Yes. FSZero never asks you to log in to Roblox, never asks for your login cookie, and never asks for your password. Account ownership is verified using bio verification: you place a short generated code in your Roblox profile bio, FSZero confirms it, and that is the entire flow. Your inventory is read using public Roblox endpoints. Bio verification is the same trust pattern used by other established Roblox community tools.

How many items does FSZero track?

FSZero tracks over 2,500 classic Roblox limiteds (all of the current Roblox limiteds). 41 hand-picked featured items receive full manipulation-free RAP analytics including price history, RAP snapshots, and sales data. The remaining items have RAP-only data.

Can I see the price history of an item?

Yes. Every featured item has price history charts including RAP over time and individual sale data points. Advanced charting with candlesticks, technical indicators, and drawing tools is in development.

Does FSZero have a trade calculator?

Yes. The trade calculator lets you pit two sides of a trade against each other with up to four items per side. It shows the net RAP and manipulation-free RAP (MFRAP) difference, each side's reseller floor and estimated USD value, manipulation flags, and a combined chart of how the items on each side would have performed together over time.

What is Advanced Mode?

Advanced Mode unlocks customization of the RAP calculation window (the default is 20 sales), finer control over manipulation filtering thresholds, and the average daily sales compute window. It is currently free.

How is FSZero funded?

FSZero is founder-funded during early access. The project is built and maintained by an independent operator with no external investors.

Who built FSZero?

FSZero is currently operated independently. Public team details may be shared at a later stage.
