List the institutional managers (hedge funds, asset managers) that file SEC 13F reports, ranked by AUM. Returns each fund's name, AUM, latest reported quarter, holdings count, and its SEC CIK — the id you pass to fund.holdings, fund.holdings.diff, fund.holdings.as_of, and fund.position.history. Start here to find which funds to track. Public-domain SEC EDGAR data.

Rank the institutional managers (13F funds) worth copying. Each row is a followable actor — name, manager, book size (AUM), holdings count, latest reported quarter, follower count, the slug (for copy.target.get), and CIK (to follow via watchlist / pull via fund.holdings). Price-derived copy-return fields are withheld unless the price-source policy and freshness gate are green. The agent-native 'who should I copy?' entry point. Sort by book size, recent activity, follower count, or gated track record. Public-domain SEC EDGAR 13F data.

Get one copy target (13F fund) by slug (from copy.leaderboard): its latest disclosed book — the top holdings you'd mirror, each with % of book and its quarter-over-quarter change (NEW/ADDED/REDUCED/EXITED) — plus book size, latest quarter, and filing history. Pair with watchlist tools to follow it. Public-domain SEC EDGAR 13F data.

Latest reported 13F equity holdings for a fund (by SEC CIK) — top positions by value, each with its CUSIP and quarter-over-quarter change (new/added/reduced/exited). Public-domain SEC EDGAR data.

Resolve a name to a tracked entity. Turn a fund or manager name (e.g. 'Berkshire', 'Citadel') into the SEC CIK or slug you pass to the fund.* tools — the entity-resolution entry point. Searches funds and managers by name or identifier.

List the US House financial-disclosure filing INDEX for a year (STOCK Act). filingType 'P' = Periodic Transaction Report (stock trades). Returns one row per filing with a link to the source PDF — this is the index, NOT parsed trades. Parsed line-items (member, ticker, buy/sell, amount range) are available via congress.trades (US House live; Senate being added). Public-domain US House Clerk data.

Find US House representatives who filed financial disclosures in a year, by name (filing index — parsed trades available via congress.trades, US House live; Senate being added).

Parsed STOCK Act transaction line-items: actual congressional stock trades by ticker or by member — buy/sell, the disclosed amount range, trade + notification dates, and owner (self/spouse). Each row links to its source PTR PDF. US House (e-filed) is live; Senate is being added. Pass `ticker` OR `member`.

Upcoming clinical-trial readout catalysts. For an industry-sponsored interventional Phase 2/3 drug trial, an ESTIMATED primaryCompletionDate is the expected topline-readout date — the binary event that re-rates a biotech ticker. Filter by sponsor (lead sponsor, INDUSTRY class), condition, phase, and a readout-date window; sorted soonest-first. Returns NCT id, title, phase, status, lead sponsor + resolved ticker (null if private/foreign), conditions, primary completion date (+ ACTUAL/ESTIMATED), and a study URL. CAVEAT: estimated dates are sponsor-self-reported and SLIP often — a readout WINDOW, not a hard date; press releases beat this feed. Public-domain ClinicalTrials.gov v2.

FDA drug-approval / rejection actions (Drugs@FDA, CDER). For a sponsor or drug, returns the regulatory action history: action=approved (AP, bullish), complete_response_letter (CR, a rejection — sharply bearish), or tentative_approval (TA). Flags new molecular entities (NME) and priority review — the highest-value catalysts. Resolves sponsor_name to a ticker (null if private). CAVEAT: backward-looking (records actions AFTER they happen, lags days; press releases beat it) — a confirmation/archive feed. Drugs@FDA is CDER-only, so biologics/vaccines (e.g. Moderna) may be absent. Public-domain openFDA.

FDA drug recalls (Recall Enterprise System). Class I = could cause death/serious harm (material adverse event); Class II/III lower. Filter by recalling firm, drug, classification, and recency; returns classification, reason, status, dates, and the recalling firm's resolved ticker (null if private). CAVEAT: enforcement data updates only WEEKLY and FDA does not revise recall status after classification — can be stale/frozen; not for real-time alerting. Public-domain openFDA.

Resolve a pharma sponsor / manufacturer name (e.g. 'Janssen Pharms', 'AstraZeneca AB') to its public ticker, so an FDA approval / trial readout / recall can be joined to 13F ownership, insider (Form 4) buys, and the confluence signal. Returns ticker, company name, exchange, and resolution method (alias|exact|fuzzy|unresolved). Returns ticker:null for private sponsors or unmatched names rather than guessing — joins must never key on a wrong ticker.

Get recent observations for a macro/economic time series from FRED (e.g. GDP, CPIAUCSL, DGS10, UNRATE).

Search FRED for macro/economic time series by keyword; returns matching series IDs and titles.

List prediction-market contracts with implied probabilities, from Polymarket and/or Kalshi. Optional keyword filter.

Get a single prediction-market contract's implied probability by platform + id (Polymarket slug or Kalshi ticker).

Cross-market divergence: for a topic keyword, pull matching contracts from Polymarket and Kalshi and compare implied probabilities to surface potential mispricing/arb. Note: matches are keyword-correlated, not verified same-event — confirm the contracts describe the same outcome before trading.

Point-in-time holdings: a fund's reported positions AS KNOWN ON a given date (no look-ahead — the most recent filing whose filedAt <= as_of). Built for backtesting.

Time-series of a single security position (by ticker or CUSIP) across a fund's filings — shares and USD value per quarter.

Quarter-over-quarter change set for a fund's most recent filing: new positions, adds, reduces, and exits (the signal in 13F).

Live SEC filing-event stream: SEC Form 4 (insider) filings today, with 8-K and 13D/G on the roadmap. Poll with `since` (a monotonic cursor) to get every filing newer than your last call; the response's next_cursor advances it. Filter by form or tickers; a form we don't carry yet returns an explicit unsupported_form note (never a silent empty page). Built for a watch loop, so call it on a schedule to never miss a filing.

Poll THIS workspace's watchlist for new filings since a cursor: every SEC Form 4 (insider) filing on the tickers your team follows, newest-after-cursor (8-K + 13D/G are on the roadmap). Pass `since` (a prior next_cursor) to get only what's new; built for a watch loop. Curate the watchlist in the Arkolith dashboard. Standard (delayed, ≤24h-old) freshness; each event carries its SEC source URL.

Like watchlist.poll but LIVE freshness — includes filings accepted within the last 24h (minute-fresh, normalized within minutes of SEC acceptance). Premium-priced and requires the Developer or Pro plan; other plans poll delayed (≤24h-old) freshness via watchlist.poll. Same workspace-watchlist scope and cursor semantics.

Insider (SEC Form 4) transactions — open-market buys/sells, awards, option exercises — for a company (by ticker) or a person (by insider name). Pass `signal: true` to restrict to open-market buys/sells (codes P/S), the tradeable subset. Pass `since` to diff only new filings.

One SEC Form 4 filing by accession number: the reporting insider, issuer, and every transaction in it (non-derivative + derivative), with net open-market flow and a link to the original SEC document. The full-filing follow-up when insider.transactions or events.latest hands you an accession_number.

Net insider activity for one company over a window: open-market buy vs sell value/shares and distinct buyer/seller counts. Answers 'are insiders net buying or selling this name right now?'

Market-wide insider cluster scan: companies where several distinct insiders made open-market buys (or sells) inside a window — the high-conviction cluster signal. Returns tickers ranked by distinct-insider count and total value.

Institutional (13F) owners of a stock by ticker — which funds hold it, position value, share count, and the quarter-over-quarter change. The 'who owns this stock' join across all tracked funds.

Cross-fund 'smart money' consensus from every tracked fund's latest 13F: the securities the MOST funds are collectively holding (mode='held'), buying this quarter (mode='bought' — NEW/ADDED cluster-buys), or selling (mode='sold' — REDUCED). The inverse of stock.owners: surfaces WHAT to look at, ranked by how many funds agree.

The moat join — where do informed INSIDERS (Form 4 open-market buys), institutional SMART MONEY (13F cluster-buys), and CONGRESS (US House STOCK Act trades) AGREE? Pass a `ticker` for all three legs on one name (insider + fund + congress net buy/sell + a verdict that escalates to triple_confluence_buy when all three are buying). Omit `ticker` for the market-wide ranked list — insider×fund names, surfaced first when Congress is buying too (triple_confluence). Joined on ticker — never a fuzzy name match. Each leg carries source provenance; congress $ are amount-range midpoints (approximate).

THE flagship 'where is smart money rotating' signal. Aggregates quarter-over-quarter SEC 13F position changes across ALL tracked institutions into per-SECTOR capital flows: which sectors institutions are net BUYING into vs SELLING out of this quarter, with breadth (how many funds agree), net flow as % of the sector's book, and a rotation rank. Price-free, point-in-time, every number traced to 13F. Answers 'is smart money rotating out of tech into energy/utilities, and is it broad-based?' — what the sell-side ships as a static quarterly PDF. Pass `period` (ISO quarter-end) for a specific quarter, else the latest well-covered one. NOT investment advice; backward-looking (13F lags ~45 days).

WHO is the smart money? Ranks institutional funds by a PRICE-FREE quality score (concentration, selectivity, AUM growth, insider co-buy) — a concentrated conviction manager scores high, a 4,000-name index fund or market-maker scores low. Each fund comes with its full component breakdown (transparent, not a black box) AND its top NEW/ADDED positions this quarter — i.e. what the highest-CONVICTION money is newly buying. (Score is a price-free conviction proxy, NOT realized track record/performance. Operating-company 13F filers are excluded.) Sort by overall score, conviction, insider corroboration, or AUM growth. PRICE-FREE; NOT investment advice.

For ONE ticker: do the independent disclosure sources AGREE? Returns the cross-source confluence verdict — institutions (13F) × insiders (Form 4) × Congress (STOCK Act) all buying/selling the same name — PLUS the capital-rotation context: which sector the ticker is in and whether smart money is rotating INTO or OUT of that sector this quarter. The two flagship signals on one name. Congress is a free corroborating leg (never the sole basis). PRICE-FREE; NOT investment advice.

Trust layer: return the source record(s) for a datapoint — origin URL, fetch time, parser version — so the agent can cite primary sources.
