• get_institution_holdings read-only

  Get current stock holdings of an institutional investor (hedge fund, mutual fund, pension fund) from their latest SEC 13F filing. Returns top positions with share counts, values, and quarter-over-quarter changes. Every answer states its grain: ENTITY (a CIK that belongs to a manager family is answered for the whole family by default -- pass entity='filer' for that one filer's own 13F) and SECURITY (the default portfolio merges an issuer's share classes into one row, e.g. GOOG+GOOGL, and lists the per-class breakdown; pass `ticker` to get only that security). Shares and value are the 13F-reported totals over all legs; option legs are flagged. structuredContent carries exact shares/values and the grain fields.

  Parameters:

  • institution (required) — string — Institution CIK number (e.g. '1067983'), slug (e.g. 'berkshire-hathaway'), or name (e.g. 'Berkshire Hathaway') — names are resolved automatically.
  • page — integer — Page number
  • limit — integer — Results per page
  • entity — string — family (default): consolidate every 13F filer in the manager family; filer: only the requested CIK's own filing.
  • ticker — string — Only this security (e.g. 'GOOG'). Returns the security grain: GOOG is Class C only, not the Alphabet issuer total.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_institutions read-only

  List top institutional investors (hedge funds, mutual funds, etc.) tracked in the SEC 13F database. Supports search by name and pagination.

  Parameters:

  • page — integer — Page number
  • limit — integer — Results per page
  • search — string — Search by institution name, CIK, or manager name (e.g. 'Klarman' -> Baupost)

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_stock_profile read-only

  Get a company's profile — sector, market cap, price, P/E ratio, 52-week range, beta, dividend yield, and other key financials.

  Parameters:

  • ticker (required) — string — Stock ticker symbol (e.g. 'AAPL', 'NVDA', 'MSFT')

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_stock_holders read-only

  Get top institutional holders of a stock from SEC 13F filings. Shows which hedge funds, mutual funds, and pension funds own the most shares, with quarter-over-quarter changes.

  Parameters:

  • ticker (required) — string — Stock ticker symbol (e.g. 'NVDA')
  • page — integer — Page number
  • limit — integer — Results per page

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_stock_activity read-only

  Get institutional buying/selling activity trend for a stock over multiple quarters. Shows how many institutions are buying vs selling, net share changes, and value flows — useful for detecting accumulation or distribution patterns. Plan limits: Free/keyless access covers the latest 13F quarter only; the multi-quarter trend requires Pro. Omit `quarters` to get the most your plan allows. structuredContent carries the exact net shares/values. Each quarter carries ko.io's comparability state (comparable / split_adjusted with its split factor / not_comparable / first_reported): a null share or value flow means UNKNOWN (withheld), never zero.

  Parameters:

  • ticker (required) — string — Stock ticker symbol
  • quarters — integer — Number of quarters to return. Omit for the plan default (Pro: 8 = 2 years; Free/keyless: the latest quarter only). An explicit value above what your plan allows returns a plan-limit error.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_stock_price read-only

  Get historical daily stock prices (OHLC). Returns a summary by default; set series=true to get the full daily price series (for backtesting / charting).

  Parameters:

  • ticker (required) — string — Stock ticker symbol
  • limit — integer — Max rows of the daily series to return when series=true.
  • period — string — Look-back window
  • series — boolean — If true, return the full daily OHLC series (up to `limit` rows) instead of just a summary.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_insider_trades read-only

  Get insider (SEC Form 4) transactions for one company. Two grains, and the answer says which: (1) with `executive_cik` -> one row per Form 4 transaction line, with its SEC code (P open-market or private purchase, S open-market or private sale, M/X/C option or RSU exercise/conversion, A grant/award, F shares withheld for tax, G gift, ...), shares, price and value; (2) without it -> one row per insider per trade date that AGGREGATES all that day's lines, split into code P/S purchases/sales (open market or private) versus all acquisitions/dispositions (which also count vests, exercises and tax withholding), with both dollar totals and the line count; when ko.io reports them, the Lines cell and structuredContent also carry that day's SEC codes (e.g. '4 (F 1, M 2, S 1)'). Do not read an aggregate day's total disposed value as a sale decision; use the P/S columns, whose dollar totals cover priced lines only (unpriced lines are counted and flagged as partial). Keyless/Free access covers the trailing 92 days; `period` beyond 1Q requires Pro. structuredContent carries the exact share counts and dollar amounts.

  Parameters:

  • ticker (required) — string — Stock ticker symbol (e.g. 'AAPL')
  • page — integer — Page number
  • limit — integer — Rows per page, 1-200
  • period — string — Trade-date window for the per-day view: 1Q = trailing 90 days (default, allowed on every plan); 2Q / 1Y / ALL require Pro. Ignored when executive_cik is given (that view returns the full history your plan allows).
  • executive_cik — string — Insider's SEC CIK (from a previous answer's person_cik, or list_insider_traders). When given, returns that insider's individual Form 4 transaction lines in this company, newest first.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_insider_traders read-only

  List executives/insiders who have recently traded their company stock. Filter by role (CEO only or all executives). Useful for finding notable insider buying/selling activity across the market.

  Parameters:

  • page — integer
  • role — string — Filter by role (case-insensitive): CEO, executive/officer, or all
  • limit — integer
  • search — string — Search by name or ticker

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_congress_trades read-only

  Search individual stock trades disclosed by U.S. Congress members (House and Senate) under the STOCK Act. Returns a markdown table of transactions: member name, chamber, ticker, buy/sell type, transaction date, disclosure date (the gap between the two reveals reporting delay), dollar amount range, and owner (self/spouse/joint). Use for questions like 'What did Nancy Pelosi trade recently?', 'Which members bought NVDA?', or 'Show the largest Senate trades this quarter'. Filter by chamber, ticker, or member name; sort by traded value, trade count, or recency. For one member's profile and complete trading history, use get_congress_member instead.

  Parameters:

  • page — integer — Page number for pagination (default 1)
  • sort — string — Sort order — volume (most traded value), trades (most trades), recent (latest first)
  • limit — integer — Trades per page, 1-50 (default 20)

  • ticker — string — Stock ticker symbol to filter by, e.g. NVDA or AAPL
  • chamber — string — Congressional chamber: house, senate, or all (default all)

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

  Get detailed trading history of a specific U.S. Congress member. Shows individual trades with transaction types, amounts, and disclosure dates.

  Parameters:

  • page — integer
  • limit — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• search read-only

  Search across institutions, stocks, and insider traders in the ko.io SEC database. Institutions match by firm name OR manager name ('Seth Klarman' -> Baupost, 'Ackman' -> Pershing Square; person hits carry matched_person). Use this first when you have a name but need the CIK number, ticker, or slug to use with other tools.

  Parameters:

  • query (required) — string — Search query — company name, ticker, person name, or institution name (min 2 characters)
  • limit — integer — Max results per category

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

  Parameters:

  • limit — integer — Max notices to return
  • ticker — string — Filter by stock ticker (e.g. 'AAPL')
  • insider_cik — string — Filter by the CIK that FILED the notice (usually the selling insider, sometimes a filing agent such as the issuer itself) -- not the issuer whose stock is sold. Leading zeros ignored; combines with ticker.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• sec_get_filing_index read-only

  • accession_no (required) — string — Accession number, e.g. '0000320193-23-000106'

• sec_get_filing_document read-only

  Get a source document from a SEC filing, served by ko.io. Returns a ko.io LINK to the rendered document (open in a browser) plus, optionally, an extracted text excerpt. Never returns the whole file — for full content, open the link or request a specific section. Requires a paid ko.io plan (Pro): on Free or keyless access the call returns an explicit plan-limit error. Use sec_list_filings / sec_get_filing_index (open on every plan) to find filings and their files.

  Parameters:

  • cik (required) — string — Company CIK number
  • accession_no (required) — string — Accession number, e.g. '0000320193-23-000106'

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_stock_financials read-only

  Get quarterly or annual financial statements for a company from SEC 10-K/10-Q filings: revenue, net income, EPS, margins, operating cash flow, cash, capex, free cash flow, buybacks, dividends, investing/financing cash flow, total assets/liabilities and debt ratios. capex, stock_repurchase (buybacks) and dividends_paid are each normally a positive cash payment (USD); negative values are passed through as filed or derived; a negative capex makes free_cash_flow null. free_cash_flow = operating_cashflow - capex only when both are reported and capex >= 0, otherwise null (never computed from a missing or negative value). cash_and_equivalents excludes short-term investments; long_term_debt is us-gaap LongTermDebt, which includes the current portion. Plan limits: the Free plan and keyless access return only the latest quarterly statement; annual statements and earlier quarters require Pro (a request for them returns an explicit plan-limit error, never 'no data'). structuredContent carries the exact reported values.

  • ticker (required) — string — Stock ticker symbol (e.g. 'AAPL', 'MSFT')

  • page — integer — Page number (default 1)

• get_ftd_data read-only

  Get SEC fails-to-deliver (FTD) data for a stock. Each quantity is the aggregate net BALANCE of shares that had failed to deliver and were still outstanding on that settlement date, as published by the SEC -- NOT the number of new fails that day. Balances carry over between days, so never sum quantities across dates (that counts the same unsettled shares repeatedly); compare levels or take the maximum instead. Fails arise from many causes (operational and processing delays, long sales, market-maker activity), and FTD data on its own is not evidence of naked short selling. Free/keyless access covers the trailing 92 days. structuredContent carries the exact share quantities.

  Parameters:

  • ticker (required) — string — Stock ticker symbol (e.g. 'GME', 'TSLA')
  • days — integer — Days of settlement-date history (default 90; Free/keyless access allows up to 92)
  • page — integer — Page number (default 1)
  • limit — integer — Rows per page, 1-500 (default 100). A long `days` window can hold more rows than one page; the answer says when the page is full and names the next one.
