Built in public
Changelog
What we shipped and when. A company that builds in public should keep receipts.
Five years of history across the new datasets
Deep backfills landed: 2.4 million FINRA short interest rows back to August 2021, 530,000+ structured product filings back to 2021, and twenty quarters of 13F holdings for all 30 tracked funds back to 2020. All served through the same free APIs and CSV exports.

Sign up with email, Google, or Microsoft and create API keys that raise your rate limit from 30 to 120 requests a minute. Usage stats live in your account dashboard. Keyless access stays exactly as it was: free, no registration.
Five new datasets: rates, calendar, short interest, predictions, ETF flows
Central bank policy rates for 49 economies back to 1945 (BIS), a US economic calendar built from BLS, Fed, and BEA schedules with post-release actuals, FINRA biweekly short interest for every US symbol, Polymarket odds tracked every 15 minutes, and spot BTC/ETH ETF holdings from issuer files.
CSV download on every dataset
Every dashboard now has a CSV endpoint, up to 50,000 rows per pull. Funding rates, COT, options, whales, insiders, 13F, everything.
Structured products tracker and 8-K events feed
Two datasets nobody serves free: every 424B2 and FWP structured note filing parsed for issuer, underlyings, coupon, and barrier (530,000 filings and counting), plus every 8-K mapped to readable event types. Both poll EDGAR every 30 minutes.
13F tracker doubles to 30 funds
Added Citadel, Millennium, D. E. Shaw, Two Sigma, Point72, Elliott, ARK, Viking, and more, with five years of quarterly history each. Every CIK verified against EDGAR before inclusion.
Services are public
Xoomar files with the SEC professionally (XBRL, 8-K, FWP, 424B2) and takes software and custom-data engagements. The site finally says so, with a contact pipeline instead of a mailto link.
