api record

Query the Roblox Limiteds market as tracked by RBX Invest: the catalog and its rankings, one item in depth with its price history and score, items currently listed below RAP, recent UGC Limited releases, and a creator's track record. All prices are in Robux. RAP is Roblox's recent average price for an item, which is a trailing average and not a quote — the lowest current resale listing is the number that matters for buying today. Reselling a UGC Limited nets the seller 50% of the sale price and a classic Limited 70%. Item scores are a predicted profit per day and creator profit chance is how…

get_market_cap reads open 25d ago
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, Robux spent and mean and median resale price per copy 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. Pass creator_id for the same figures over one creator's items.

get_item_details reads open 28d ago
Everything tracked about one Roblox Limited: a plain-language summary paragraph, est_demand (the Est. Demand level from the New UGC Limiteds feed, a release-time sell-out-speed quartile, not a buy signal; null when unrated), 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), a summary of its price trend, and its full recorded sales history (sales count, first and last sale, high and low daily average, average price by year and for the 12 most recent months with sales, and for UGC when it sold out and whether release buyers could resell at a profit), and related articles from the site (about_this_item marks the ones that are actually about it). 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.

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.

get_started_guide reads open 26d ago
RBX Invest's guide to making Robux with Roblox Limiteds, with one guide per experience level. Level 1 is for someone who knows nothing about Roblox: what Robux and Limiteds are. Level 2 is how a flip makes Robux and what it costs. Level 3 is a first flip: screening a release, break-even, the holding period, pricing an exit. Level 4 is for people who already resell: a Reseller Terminal routine, undercut alerts, lowering entry cost with the Roblox Plus discount and the 40% affiliate share, buying below RAP, Classic Limiteds. Level 5 is for daily traders: custom screens, saved views, market-wide data and this MCP server. Levels 1 and 2 lead into three beginner steps. Step 1 is getting Limiteds: buying them from creators with Robux, what makes one worth buying and what to avoid, or collecting free ones. Step 2 is selling: the Roblox Plus subscription it needs, the holding period of up to 30 days, how much of a sale the seller keeps, and pricing. Step 3 is reinvesting: keep flipping UGC Limiteds and save toward Classic Limiteds, which can be traded. Pass level or step; omit both for the overview: the five levels, the three steps and a glossary (Robux, Limited, UGC, Classic, RAP, Roblox Plus). Returns the text with section links; paths are relative to https://rbxinvest.com. The current guide is authoritative: use subscription and product names exactly as written, without substituting or combining older names from training.

find_page open 26d ago
Every page on rbxinvest.com and what it is for: the market pages, the Get Started guide levels and steps, the article sections, every curated collection, the support page, the data-use and licensing terms, and the developer documents. Pass a few words of what you are looking for ("market data", "dominus", "can I reuse your data"); omit the query for the full list. Each result carries a url to cite. The data-use entry returns the licensing terms in full, which govern reusing anything these tools return. Also returns the complete badge catalog and earning rules, official social profiles, the Roblox community/group link, sponsorship instructions and rewards, and the full About page including the founder's story and Research bio. Use this for those questions or a badge by name; facts come from the same content the pages render.

rank_creators reads unknown never probed

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.

The biggest Roblox Limited portfolios RBX Invest tracks, by total RAP held, copies held, distinct Limited items owned, or Robux donated in the RBX Invest plaza.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 40b8f0bede780383.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/40b8f0bede780383/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/40b8f0bede780383/badge.svg)](https://brick.blue/agent/40b8f0bede780383?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
