The open data and intelligence layer
for global finance.
Structured financial data, research, standards and intelligence — built for people, developers and AI agents. Every page here has an API twin.
One structured map of the financial world
Not articles — entities. Companies, markets, assets, funds, banks and countries, each with stable identifiers, typed fields and relationships.
Markets
The venues: NYSE to Tadawul, with MIC codes, operators and jurisdictions.
48 exchanges →Companies
Listed companies as structured entities: ticker, venue, sector, country.
121 companies →Assets
Asset classes and benchmarks: indices, bonds, FX, commodities, crypto.
56 assets →Funds
ETFs, hedge funds and sovereign wealth — the world's largest pools of capital.
32 funds →Banks
Systemically important banks with jurisdictions and balance-sheet scale.
20 banks →Economy
The macro dashboard: what each indicator means and who publishes it.
8 indicators →Crypto
Bitcoin, Ethereum, major layer-1s and stablecoins as first-class financial entities.
9 crypto assets →Countries
Currencies, central banks, markets and GDP by jurisdiction.
37 jurisdictions →Everything is connected. The data should be too.
A company issues a security, which lists on a market, in a country, whose central bank sets the price of money — while funds hold the security. Finance Foundation models finance as typed entities and typed relationships, not disconnected tables.
Live example: open Apple and follow the connections — or explore the whole graph as an interactive map. Every edge is a real link on this site and in the API.
Structured, sourced, honest
Reference data on the world's most important financial entities. Clearly versioned (seed-0.7 · marketcap-1 · 2026-08-30), approximate by design, never pretending to be real-time.

Intelligence, not news
Structural research on financial infrastructure — markets, data, identifiers, stablecoins and AI. No price targets, no hot takes.
The Open Financial Data Stack, 2026
Where open financial data actually stands: what is genuinely open, what is licensed, and where the gaps are for builders and AI agents.
Markets · 2026-08Mapping the Global Exchange Landscape
A structural map of the world's stock exchanges: who owns them, how they concentrate, and why listing venues and trading venues are diverging.
Crypto · 2026-08Stablecoins as Market Infrastructure
Stablecoins stopped being a crypto niche and became a parallel dollar-settlement system. What that means for banks, payments and data.
The whole site is an API
Open, versioned, no key required. JSON with CORS enabled — usable from a browser, a backend, or an AI agent tool call.
Try it now — no signup:
Built agent-first
Give AI agents structured access to financial knowledge: stable entities, typed relationships, honest provenance and a machine-readable index at /llms.txt.
AI financial analyst
Ground an analyst agent in clean entities and relationships instead of scraped HTML.
Company & market intelligence
Resolve "which company is this" with identifiers, then traverse the graph for context.
Automated research
One GET returns the full dataset — small enough for a context window, structured enough to reason over.
A common language for financial data
Identifiers (LEI, ISIN, MIC, FIGI), classifications, and the Finance Foundation Schema — open definitions of financial entities and the relationships between them.
Build on Finance Foundation
Use the open API in your app or agent. Read the research. Adopt the schema. The foundation layer is free and open — the ecosystem grows on top.
