European Central Bank (ECB) - Statistics & Data

European Central Bank Statistics & Data is the ECB's primary source for euro-area statistics, policy rates, FX reference rates, yield curves, inflation, macro indicators, downloads, and SDMX access. It supplies the data behind macro research, not investment-app commentary.

The FDIC's free lookup and data service covers insured U.S. banks and branches, bank histories, structure changes, failures, financials, deposits, API access, and bulk files.

Federal Reserve Bank of New York - Data & Statistics

The New York Fed publishes reference rates, market-operations data, SOMA holdings, primary-dealer statistics, surveys, and research indicators. It is useful for SOFR, EFFR, OBFR, funding markets, Treasuries, agency MBS, and macro data through exports and APIs, not for screening or trading.

Federal Reserve Board (FRB.gov)

FRB.gov is the Federal Reserve's primary source for policy material, FOMC dates, statistical releases, interest rates, balance sheets, bank data, FX, industrial production, and downloadable series. It is official macro infrastructure, not a commercial investing terminal.

Find and update company information (Companies House)

Companies House Find and update company information is the official UK register for companies, filings, officers, people with significant control, and document images. Use it for private-company checks, due diligence, filing alerts, and registry-driven applications. It is primary registry data, not analyst research.

FINRA Fixed Income Data

FINRA Fixed Income Data publishes U.S. bond details, TRACE transactions, trade history, and aggregate market reports. It is useful for checking executed prices and volumes. TRACE is not a live quote system, exchange, or execution venue.

FRED (Federal Reserve Economic Data)

FRED is the Federal Reserve Bank of St. Louis' free macroeconomic database. Use its series, charts, release calendar, Excel tools, mobile apps, and REST API for inflation, rates, GDP, employment, FX, credit, and market indicators. It is macro context, not equity fundamentals or brokerage infrastructure; API access needs a free key.

Hong Kong Exchanges and Clearing (HKEX)

HKEX is the official source for Hong Kong listed-company announcements, HKEXnews filings, calendars, alerts, delayed quotes, and licensed market-data services. Use it for primary-source disclosures and exchange feeds. Real-time, historical tick, full order-book, and redistribution rights require paid products and licensing.

Nasdaq.com

Nasdaq.com offers exchange-branded quotes, news, screens, calendars, filings, options chains, watchlists, portfolios, company financials, ownership, and IPO context.

Office of Financial Research (U.S. Treasury)

The Office of Financial Research publishes U.S. Treasury financial-stability monitors, funding data, money-market transparency, bank risk views, and hedge-fund datasets in public JSON and CSV. It supports macro and market-structure research, not real-time trading, stock screens, or portfolio tracking.

Open Payments (CMS)

Open Payments is CMS's public database of payments, research funding, and ownership interests reported by drug and device companies and group purchasing organizations. It covers physicians, certain non-physician practitioners, and teaching hospitals. A published payment does not mean the relationship was improper.

OTC Markets

OTC Markets provides public issuer pages, tiers, quotes, news, filings, screens, and licensed Level 1 and Level 2 products for OTC securities. It is useful for OTC research and feeds, not a global terminal, broker, or free redistribution source.

USAspending

USAspending.gov is the U.S. government's free source for federal awards, contracts, grants, loans, recipients, agencies, spending categories, maps, downloads, and APIs. It can add contract and government-demand context to company research, but it is not market data or a valuation service.

World Bank Open Data (data.worldbank.org)

World Bank Open Data provides free global indicators, country profiles, downloads, charts, and APIs for development, demographic, and economic research. It is not a security screener or broker.
