Changelog
New datasets, endpoints, plan changes and data corrections, newest first. Every entry has a permanent link; the feed is at /changelog/feed.xml.
Gate.io reports liquidation sizes in contracts; the qty field on its rows now holds coins (a BTC contract is 0.0001 BTC, an ETH contract 0.01 ETH), as it does for every other venue. Dollar values were already right and are unchanged.
A dedicated page at /refunds sets out how to cancel a plan, what happens when you do, when a payment is refunded and how to ask. Linked from the footer, the terms, the pricing page and the account's Plan tab.
The terms now set out what every visitor may do with the data for free, what the paid plans add, refunds and the uptime commitment. The privacy policy says what we collect, who processes it, how long it is kept and how to delete it. Visitors in the EEA, the UK and Switzerland see a cookie banner before any analytics or advertising cookie is set; the Cookies link in the footer reopens it.
Pro ($19 a month) adds 120 requests a minute, full history, bulk CSV export, webhook alerts and a commercial licence on the 20 public-domain datasets; Ultra ($39) adds 300 a minute and five keys; Enterprise starts at $199. Checkout opens soon, and seven days after it does the free limits become 10 requests a minute without a key and 30 with a free key, both with six months of history and both free forever; keys created before then keep 120 a minute until that day, and every key holder gets the date by email a week ahead. Every dataset stays free to read. Details on the pricing page.
Every dataset is a tool at https://xoomar.com/mcp over MCP's Streamable HTTP transport, with the same limits as the API; a free key raises them. The local server stays available with npx xoomar-mcp.
Reported earnings dates for every US filer since January 2023, read from 8-K Item 2.02 filings, and for each company the expected date of its next report, labelled as an estimate with the date it stands on. On /markets/earnings, as JSON and CSV, per company at /api/markets/earnings/{ticker}, on every company page and as a tool on the MCP server.
The prediction-market dataset, its hub page and its endpoints are gone and answer 410; the source's terms do not allow the data to be republished. 31 datasets remain, all free.
Companies where several insiders bought on the open market in the same window, with the officer purchases singled out, at /api/markets/insiders/clusters and on the insiders hub.
The daily threshold securities lists from Nasdaq and Cboe since January 2022, by day or by symbol, at /api/markets/threshold-list and on the short-interest hub with the longest current streaks.
Every Treasury auction since 2010 with the high yield, bid-to-cover and the indirect, direct and dealer takedown, plus the announced calendar, at /api/markets/treasury-auctions. The whole API is described in OpenAPI 3.1 at /openapi.json.
Kraken Futures and BitMEX join Binance, Bybit, OKX and Hyperliquid on the funding-rate and open-interest feeds, with each venue's interval and an annualised figure per row. BitMEX open interest is stated in coins and dollars, corrected for dates 12 June to 14 September 2026.
OKX reports liquidation sizes in contracts; they are now converted at each contract's value, and every OKX event and hourly total in that window has been restated. Gate.io and HTX rows are unchanged.
/api/markets/liquidations/recent filters by contract, exchange, side and minimum notional. /api/markets/liquidations/history serves the hourly totals, which are kept permanently, for any date window.
PPI, JOLTS, weekly jobless claims, PCE, retail sales, housing starts and permits, new home sales, durable goods, industrial production, trade, construction, inventories, factory orders, the FOMC minutes and the Beige Book join CPI, payrolls, GDP and the FOMC decision, all from the agencies' own schedules. After each release the actual and the previous print are filled in, with a unit field.
Fails to deliver (from January 2010), daily short volume (from August 2021) and Form 4 filings (from 2020) take from, to and limit, so a symbol's full series comes back in one request.
Fed liquidity (the balance sheet, reserves, reverse repo, the TGA and net liquidity), company financials and buybacks from XBRL, Form D private placements, the IPO pipeline, bitcoin treasuries and federal contracts, each with a hub, JSON and CSV. One page per US listed company at /markets/stocks/{ticker} brings its short interest, filings and financials together.
pip install xoomar and npm install xoomar give typed clients for every endpoint; npx xoomar-mcp runs the MCP server locally for assistants; every chart can be embedded from /embed with an attribution link.
Spot bitcoin and ether ETF holdings and flows now come only from the issuers' published holdings files (IBIT, ETHA, BITB, ETHW and ARKB today); the figures a third party compiled are kept as history to 11 September 2026 and no longer updated.
Short interest history reaches August 2021 for every US symbol, structured product filings reach 2021, and the 13F tracker carries twenty quarters back to 2020 for all 30 funds, through the same APIs and CSV downloads.
Sign up with email, Google or Microsoft, create an API key and see your own usage in the account dashboard. A key raises the limit from 30 to 120 requests a minute. Keyless access stays as it was: free, no registration.
Central bank policy rates back to 1945, a US economic calendar with post-release actuals, FINRA short interest for every US symbol, and spot BTC and ETH ETF holdings.
Every dataset has a CSV endpoint at /api/markets/{dataset}/csv, up to 50,000 rows per pull: funding rates, COT, options, whales, insiders, 13F, everything.
Every 424B2 and FWP structured note filing since 2021, parsed for issuer, underlyings, coupon and barrier, and every 8-K with its item numbers mapped to readable event labels. Both update within 30 minutes of a filing.
Citadel, Millennium, D. E. Shaw, Two Sigma, Point72, Elliott, ARK and Viking join Berkshire, Bridgewater, Scion and the rest, each with five years of quarterly history.
