Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

market
get_market_cap
How big the Roblox Limited market is over any date range, split between Classic and UGC Limiteds: market cap, items, copies in circulation, and the marketplace sales volume and Robux spent on the latest measured day, plus a sampled daily series carrying all of them. Market cap is the RAP of each item times the copies of it that exist. Use it for how big the market is, whether it is growing, how marketplace sales compare, and how the two halves differ. Item-for-item trades are excluded.
get_market_stats
Totals for the Roblox Limiteds market as RBX Invest tracks it: how many Limiteds are followed, and the copies and Robux held across tracked portfolios. The holdings figures cover RBX Invest users who linked a Roblox account, not all of Roblox.
rank
rank_creators
Creators ranked across the whole Roblox Limited market — who is biggest, and whose releases most often end up profitable. get_creator answers about one creator you can already name; this finds them. Ranking by profitability shows only creators with enough settled releases to rate, and by growth only those with 3 or more items, because an average over one release is noise.
rank_players
The biggest Roblox Limited portfolios RBX Invest tracks, by total RAP held, copies held, or average lifetime appreciation. This covers people who signed up on RBX Invest and linked a Roblox account, not every Roblox player, so a rank from it is a rank on this board rather than a global one.
articles
find_articles
Search RBX Invest's published guides. They cover the market — how Roblox taxes resales, how RAP is calculated, valuing and flipping Limiteds, converting Robux to USD, histories of individual item series — and the site itself, in the "site" section: linking a Roblox account and what that grants, inventory syncing, privacy, what each page does. Returns titles, summaries and links — read the article itself for the detail. One search returning nothing is a vocabulary miss more often than a gap; try the words the site would use before concluding it is not there.
community
get_community_holdings
The Limiteds and creators most held across the portfolios RBX Invest tracks. A different signal from price or sales volume: RAP says what a thing trades at, this says what people chose to keep. Ranked by total copies held or by how many different people hold it — one item can be 33 copies in a single collection and another one copy each across 400 people.
creator
get_creator
A Roblox UGC creator: how often their releases have ended up profitable, how long that typically took, and their biggest items. Creators with too few releases come back unrated rather than scored — treat that as unknown, not as bad.
deals
find_deals
Roblox Limiteds whose lowest resale listing is currently below their RAP, with the discount and the absolute saving. This is the live resale market, refreshed continuously. Use it for what is underpriced right now.
item
get_item_details
Everything tracked about one Roblox Limited: a plain-language summary paragraph, RAP and how it has moved over a window, the resale book (how many copies are listed and at what prices, not just the cheapest), stock left, sales in the last 30 days, whether the creator is still selling new copies, the creator, the item score with its predicted profit per day and a breakdown of how it was calculated (every input, its weight and how many points it moved the chance and profit-size blends, then the equation), and a summary of its price trend. Use the breakdown to explain why an item scores what it does. Needs a numeric Roblox asset id — get one from search_items first. Read creator_still_selling rather than copies_remaining to answer "can I buy one at the original price": stock left does not mean it is on sale.
items
search_items
Search the Roblox Limited catalog by name, or screen the whole market when no query is given. Returns asset id, RAP, RAP across every copy sold, the lowest resale listing, stock left, the move in RAP over 1/7/14/30 days and lifetime in both percent and Robux, sales counts and sales value per window, and the item score. Rank by any of those with sort, and bound any of them with filters to ask a question with more than one condition in it. Prices are Robux.
new
get_new_limiteds
UGC Limiteds released recently, with demand level, stock left and the predicted profit numbers RBX Invest scores them with.
player
get_player_holdings
What a tracked player holds: their most valuable positions plus the totals the leaderboard ranks them on. Follows rank_players, which returns the Roblox user id this needs. A player who set their inventory private comes back marked private rather than empty.
