xoomar

Python client for the XOOMAR free market data API: 29 datasets from primary sources (SEC EDGAR and XBRL, FINRA, CFTC, the Federal Reserve, USAspending, exchange APIs) as clean JSON, no key needed to start.

pip install xoomar

from xoomar import Xoomar

x = Xoomar()                          # 30 requests a minute; Xoomar(api_key="...") for 120 with a free key

x.short_interest("GME")[0]            # FINRA short interest, newest settlement first
x.short_volume("GME", days=30)        # FINRA daily short sale volume
x.fails_to_deliver("GME")             # SEC fails to deliver
x.insiders("NVDA")                    # SEC Form 4 trades
x.large_holders("HIMS")               # Schedule 13D and 13G holders
x.financials("AAPL")["quarterly"]     # XBRL income statement by quarter
x.fund_holders("AMZN")                # which tracked 13F managers hold it
x.cot("gold")                         # CFTC positioning history
x.fed_liquidity()[-1]                 # net liquidity, oldest first, so [-1] is this week
x.funding_rates()                     # perpetual funding on three exchanges
x.bitcoin_treasuries()                # bitcoin on public balance sheets
x.form_d(days=7)                      # private placements filed this week
x.federal_contracts(ticker="LMT")     # federal contract actions

Every method returns the data part of the response. History endpoints keep the API's own order (short interest, insiders and COT newest first; short volume, fails to deliver and Fed liquidity oldest first), each row carries its date, so sort if you need one direction; x.last_meta holds updatedAt, source, license and attribution from the last call. x.get("short-interest", symbol="TSLA") calls any endpoint directly and x.csv("short-interest/csv") fetches a CSV download.
