Is siliconfloor live?

Yes — it answered the hub's last check (checked 4h ago). It answered 100% of checks over the last 30 days.

Is siliconfloor free to use?

Yes — the hub reached it with no key and no payment.

What tools does siliconfloor have?

16 tools: what_changed, list_companies, get_company, compare_companies, screen_companies, get_ownership, get_filings, get_signals, ….

Is siliconfloor safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_dividends open 4h ago

  Dividend picture: yield, per-share amounts, growth, and whether cash flow actually covers the payout. Payments are observed in the tape, not taken from a promise. Projections never exceed measured coverage. Without a symbol, returns the highest-yielding payers across the sector. A company outside the ranking (a foreign issuer, for instance) returns the payments observed in its price history. Estimates, never advice.

• get_holders open 4h ago

  The AI and semiconductor universe read by holder. Without `holder`: the largest institutional holders from SEC Form 13F (value held, whole 13F book, share of the book placed in the universe, top segments, net move since the previous quarter), the universe companies that invest in each other (NVIDIA, Alphabet…), and the sector rotation (bought, sold, net by segment, valued at current-quarter prices, on holders present at both quarters). Holders that file no 13F but declare a stake above 5% in Schedule 13D/G — individuals (Elon Musk, Peter Thiel…), companies holding a stake — are listed apart (`list: 'declarants'` or `'individuals'`), valued at the quarter's reference prices. With `holder` — a key from a list, a name ('Vanguard', 'Elon Musk', 'Jensen Huang') or a director's SEC CIK — one holder in detail. A fund or an investor: positions by company (shares, value, weight, share of the company's capital, move, `heldSince` — the first quarter of its unbroken run of 13F declarations), sectors, flows, Schedule 13D/G declarations, and `history`: what it declared in the universe every quarter since the end of 2019. A person (or a 13D/G declarant): one page for everything they file — `breakdown` splits each stake at the last price into shares held (and how: own name, trusts, companies), restricted ("bonus") shares, options (exercise price, expiry) and other rights, per the filings' own words and never guessed (`undetailed` otherwise); `insiderRoles` and `insiderFilings` give their Forms 3, 4 and 5. A person can have two true figures for one company: the shares held (Form 4) and what the SEC counts as theirs (Schedule 13D/G, which adds options exercisable within 60 days and unvested shares that vote): say which one you quote. Entities of a house are summed; a line whose value contradicts its share count is set aside; a value filed in thousands is scaled. `coverage.complete` false means a floor, not a market fact.

• get_market open 4h ago

  The AI and semiconductor universe as one market, over time: combined market cap, the weight of each segment or company, and traded dollar volume, session by session for up to a year (weekly points over five years), plus the map of one session (every company's market cap, volume and day change). Use it for 'how has NVIDIA's weight changed', 'which segment grew the most this year', 'where is the volume going'. Market cap of a past day = adjusted close × shares outstanding at that date (from SEC filings); the last point is today's figure. Built once per session after the close. Amounts in US dollars, weights as fractions. `enteredOn`: first session of a company listed during the period (an IPO, not a data gap).

• what_changed unknown never probed

  Everything the system observed and dated since a given moment: SEC filings accepted, figures a company RESTATED, technical signals logged, and institutional ownership declarations. Use this instead of diffing two snapshots yourself — a snapshot cannot tell you WHEN something appeared. Ideal for a daily brief, a watcher, or catching up after being away. A price move is not an event here: it is a state, and get_company reports it. By default returns `highlights`: the whole window ranked by materiality — restatements, earnings, material agreements, offerings and sizeable insider buys first, technical signals last — with repeated items on one line (a signal across companies in a session, a company's insider filings of one kind with their total amount, a company's 13F declarations). Ownership declarations say what they change: a Schedule 13D/G carries `move` (crossed 5%, up, down, below 5% — no longer required to report, NOT a sale —, out) with `previousPercent` and `changeVsPrevious`; a 13F row carries `moves`, what that manager did with the tracked companies since the previous quarter (exits named, reductions, increases, dollars sold and bought) — a 13F never names what it sold, it leaves it out. `complete: false` means a source had more than was read: the summary is complete after `coversFrom` — narrow `since` or pass `symbol`. Pass detail: 'events' for the raw chronological list.

Every figure carries the date of the data it comes from, and comes from the company's own XBRL filings rather than a data vendor's summary.

  Filter the tracked universe on growth, margins, valuation, size, trend or segment, and sort by any of them. Use this to answer 'which AI companies grow above 40% with a gross margin above 60%' in one call instead of walking the list. A company whose filtered figure does not exist (not filed, or a ratio between two currencies) is listed apart in `notComparable` with the reason — it is not below your threshold.

• get_ownership unknown never probed

  Holders of a company, rebuilt from the SEC filings themselves (Schedule 13D/G, Form 13F, and the Forms 3, 4 and 5 that directors, officers and 10% owners file themselves). Each holder carries the accession number of the filing that declares it. Total declared ownership is given as TWO BOUNDS, never one number: two managers can report the same shares and the filings do not say which. The low bound counts once every position that the filings themselves show another manager may also report (an included manager that files its own 13F, or one that cannot be identified); the high bound adds every declaration. Report the range, not a single figure. The high bound can exceed 100%: shares lent to short sellers are declared by the lender and again by the buyer, a sub-adviser and its client can both report the same shares, and a 13G counts shares obtainable from convertibles or warrants. A 13F table copied into another filer's report is counted once. Always check `coverage`: when it is incomplete, the totals are a floor and the remainder is NOT float. `funds` lists the mutual funds and ETFs that hold the shares, from their own Form N-PORT reports: the same shares are inside their managers' 13F, never add them. For a reference ETF (SMH, QQQ, IWM), `etfHoldings` is the other side: the tracked companies inside the fund and their weight, from the fund's own N-PORT report. Directors, officers and 10% owners in office are counted in the holders and the totals as well (source "Form 4", their declared role in `insider`), once each: a joint filing with a fund, lines held through an entity already listed, the same shares declared by a spouse, or a person whose Schedule 13D/G is more recent are not added again; overlaps the filings cannot settle (family companies named differently by two relatives) sit between the low and high bounds. For directors, officers and 10% owners, `changeVsPrevious` is their movement since the `quarterlySnapshot`, on the shares counted here (`previousAsOf`: the filing that described their holding then); those who fell below the naming threshold since are in `insidersMovedBelowNamingThreshold`. `insiders` lists all of them with the shares each declared after their latest Form 3, 4 or 5 (the filing is linked) — already counted above, never add them again. Each holder and insider carries `holder`: pass it to get_holders for the detail — for a person, each stake broken down into shares held, restricted shares and options. `history` gives every quarter since the end of 2019 from the 13F filings (managers declaring the stock, shares, percent of the company at that date as an upper bound, value, stock pickers' part), and a 13F holder's `heldSince` the first quarter of its current unbroken run of declarations (`orEarlier`: since the start of the history). `moves` treats every change of a position as an event between two declarations of the same kind by the same holder: the 13F moves of the quarter (every manager that entered, increased, reduced or exited — `moves: "sales"` lists every reduction and exit), each Schedule 13D/G of the period with its nature (`crossed` 5%, `up`, `down`, `below` 5% — no longer required to report, NOT a sale —, `out`), and insiders since the snapshot. A 13F line whose value contradicts its share count is never read as a sale: that manager has no move (`unreadableManagers`).

• get_financials unknown never probed

  A company's income statement, balance sheet and cash flow statement as filed with the SEC in XBRL: the last 12 calendar quarters or the last 6 fiscal years, 30+ lines, with the filing behind each period. Lines computed from filed lines say how (`computed`); a null is a line the company did not file for that period: report it as unknown. Cash outflows (capex, buybacks, dividends paid) are negative. A foreign private issuer files once a year: its statements are fiscal years whatever the basis asked. Amounts are in the filing currency. For a foreign issuer that publishes its quarters only in releases filed as Form 6-K (TSMC), `releases` adds its monthly revenue, quarterly results and guidance — unaudited, and kept apart from the statements.

• get_figure_history unknown never probed

  One figure for one company — revenue, gross profit, operating income or net income — over its last eight quarters (fiscal years for a company that files once a year), with the SEC filing behind each period AND what the company had filed before any restatement. Use this when a number matters enough to be checked or cited: it returns a permanent page address for it. A restatement is itself information: a company that revises a figure months later is worth a remark. For every line of the statements, over 12 quarters or 6 fiscal years, use get_financials.

• get_price_history unknown never probed

  Daily bars adjusted for splits and dividends, up to five years (about 1,260 sessions). Compact: `fields` names the columns once and each bar is one row in that order, oldest first. Use it to compute your own statistics rather than trusting a summary.
