## Tools
- fund.list - 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. Endpoint: https://arkolith.com/api/mcp
- copy.leaderboard - 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, and the slug (for copy.target.get) + CIK (to follow via watchlist / pull via fund.holdings). The agent-native 'who should I copy?' entry point. Sort by book size, recent activity, or follower count. Public-domain SEC EDGAR 13F data. Endpoint: https://arkolith.com/api/mcp
- copy.target.get - 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. Endpoint: https://arkolith.com/api/mcp
- fund.holdings - 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. Endpoint: https://arkolith.com/api/mcp
- search - 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. Endpoint: https://arkolith.com/api/mcp
- congress.disclosures.list - List US House financial-disclosure filings for a year (STOCK Act). filingType 'P' = Periodic Transaction Report (stock trades). Returns the filing index + a PDF link per filing; transaction line-items live in the PDF. Endpoint: https://arkolith.com/api/mcp
- congress.member.search - Find US House representatives who filed financial disclosures in a year, by name. Endpoint: https://arkolith.com/api/mcp
- macro.series.get - Get recent observations for a macro/economic time series from FRED (e.g. GDP, CPIAUCSL, DGS10, UNRATE). Endpoint: https://arkolith.com/api/mcp
- macro.series.search - Search FRED for macro/economic time series by keyword; returns matching series IDs and titles. Endpoint: https://arkolith.com/api/mcp
- predictionmarket.list - List prediction-market contracts with implied probabilities, from Polymarket and/or Kalshi. Optional keyword filter. Endpoint: https://arkolith.com/api/mcp
- predictionmarket.quote - Get a single prediction-market contract's implied probability by platform + id (Polymarket slug or Kalshi ticker). Endpoint: https://arkolith.com/api/mcp
- divergence.scan - 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. Endpoint: https://arkolith.com/api/mcp
- fund.holdings.as_of - 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. Endpoint: https://arkolith.com/api/mcp
- fund.position.history - Time-series of a single security position (by ticker or CUSIP) across a fund's filings — shares and USD value per quarter. Endpoint: https://arkolith.com/api/mcp
- fund.holdings.diff - Quarter-over-quarter change set for a fund's most recent filing: new positions, adds, reduces, and exits (the signal in 13F). Endpoint: https://arkolith.com/api/mcp
- events.latest - Live SEC filing-event stream. 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 (e.g. '4' for insider Form 4) and/or tickers. Built for a watch loop — call it on a schedule to never miss a filing. Endpoint: https://arkolith.com/api/mcp
- watchlist.poll - Poll THIS workspace's watchlist for new filings since a cursor — every Form 4 / 8-K / 13D-G on the tickers your team follows, newest-after-cursor. 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. Endpoint: https://arkolith.com/api/mcp
- watchlist.poll.live - Like watchlist.poll but LIVE freshness — includes filings accepted within the last 24h (minute-fresh, normalized within minutes of SEC acceptance). Premium-priced. Same workspace-watchlist scope and cursor semantics. Endpoint: https://arkolith.com/api/mcp
- insider.transactions - 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. Endpoint: https://arkolith.com/api/mcp
- insider.company - 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?' Endpoint: https://arkolith.com/api/mcp
- insider.clusters - 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. Endpoint: https://arkolith.com/api/mcp
- stock.owners - 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. Endpoint: https://arkolith.com/api/mcp
- signal.crowding - 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. Endpoint: https://arkolith.com/api/mcp
- signal.confluence - The moat join — where do informed INSIDERS (Form 4 open-market buys) and institutional SMART MONEY (13F cluster-buys) AGREE? Pass a `ticker` for both legs on one name (insider net buy/sell + which funds hold/are adding + a confluence verdict). Omit `ticker` for the market-wide ranked list of names BOTH insiders and funds are buying. Joined on ticker — never a fuzzy name match. Each leg carries source provenance. Endpoint: https://arkolith.com/api/mcp
- provenance.get - Trust layer: return the source record(s) for a datapoint — origin URL, fetch time, parser version — so the agent can cite primary sources. Endpoint: https://arkolith.com/api/mcp
- account.balance - FREE (0 credits). Return this API key's credit balance (free + paid), USD value, and top-up URL. Call this to self-monitor before/after spending — checking your balance never costs credits. Endpoint: https://arkolith.com/api/mcp
- feedback.submit - FREE (0 credits). Tell the Arkolith team what data you wish existed, report wrong/missing data, or suggest an improvement. Use this whenever a dataset you needed wasn't available or a result looked off — it directly shapes what we build next. Endpoint: https://arkolith.com/api/mcp
