Public-market data · REST · MCP · Terminal
Filings, ownership, and market context — one API for teams and agents.
FinUties is the public-finance core you can query the same way in code and in the Terminal: SEC filings, institutional ownership, equities, positioning, rates, economics, and calendar — with published freshness budgets, not vague “real-time” claims.
Free during the public test (90-day keys). Seven commercial domains only. Not investment advice.
- One contract
- REST · MCP · Terminal
- Same resource names everywhere — less glue code.
- Beyond quotes
- Filings + ownership
- Plus positioning, rates, economics, calendar.
- Honest freshness
- Published budgets
- We say how recent we aim to be — and when degraded.
Built for people who ship on public data
Product & research engineers
Wire filings and holders into apps without stitching five vendors.
Agent / MCP builders
Same catalogue over MCP — agents call what humans see in Terminal.
Analysts who want a Terminal
Explore entities and ownership on the open-source Terminal — not a sealed desk.
Not a Bloomberg replacement, not HFT tick feed, not a broker. If you need nanosecond quotes, pick a market-data specialist — we focus on the governed public-finance core.

Clear boundaries
We name what is not on offer so you are not surprised later.
Not a tick / HFT feed
We publish freshness budgets for the public-finance core — not nanosecond market data.
Not a broker
No live execution product. Internal analytics R&D stays off the commercial surface.
