Agents should not scrape HTML for dark pool data API MCP. Eulerpool exposes this dataset as typed JSON and as an MCP tool, so Claude, Cursor, or a custom worker can request market structure data without inventing a number.
Give Claude, Cursor, or a custom agent typed dark pool volume — REST plus native MCP tools, no scraping.
What the data contains
- FINRA-reported dark vs. lit volume for every US equity
- ATS-level venue breakdown and short-volume ratio
- The institutional flow tape that the lit tape hides
Install and call
Use REST, an official SDK, or the Excel add-in — same data. Ticker in the examples is AAPL.
curl -H 'Authorization: Bearer YOUR_KEY' \
'https://api.eulerpool.com/v1/darkpool/{ticker}/volume'Authentication
Send Authorization: Bearer YOUR_KEY. Keys are created at register in under a minute. Official SDKs take the key in the constructor; Excel stores it in the add-in settings. There is no key-in-query-string mode — do not paste tokens into public notebooks.
Primary route for this article: /v1/darkpool/{ticker}/volume. Docs: /financial-data-api.
Coverage and freshness
Eulerpool maps 100,000+ securities across 90+ exchanges. dark pool data API MCP rides that same reference layer — identifiers resolve through ticker, name, ISIN, or CUSIP via search, so a European name is not a dead end. History depth depends on the source: prices go back decades, 1-minute bars to 2010, 13F to 2013, macro often 50+ years.
Paid plans can stream quotes over WebSocket; the free plan uses REST with a 15-minute delay on real-time equity fields. Fundamentals, ownership, and calendars are identical on every plan. Rate-limit headers ship on every response. Batch routes (up to 100 symbols) count as one request.
MCP wiring
Point an MCP client at Eulerpool and the agent sees this dataset as a tool, not a blob of markdown. That is the difference between “search the web for a P/E” and “call the ratio endpoint.” Docs: MCP server.
Fit versus other sources
Most teams land here after fighting Yahoo Finance scrapers, Alpha Vantage’s 25-request/day ceiling, or a Polygon bill that ignored fundamentals. Eulerpool is a licensed dark pool data API MCP with statements, estimates, filings, and macro on the same key — and a terms of service you can actually show legal.
Deep comparisons live here: vs Alpha Vantage, vs Polygon, Yahoo Finance alternative, best stock market APIs in 2026.
Who should call this
- Quant research — pandas/R dataframes, point-in-time fields, 20+ years of history where the source publishes it.
- Fintech apps — watchlists, screeners, and portfolio views without relicensing Bloomberg for every customer.
- AI agents — typed JSON and a native MCP server so models stop inventing numbers for Dark Pool Data.
- Spreadsheets — the Excel and Google Sheets add-in covers the same endpoints as REST.
Dark Pool Data API for AI Agents and MCP Clients is one slice of the Eulerpool Financial Data API. Adjacent routes — quotes, statements, ownership, macro — use the same key, so a prototype that starts here does not hit a wall at the second dataset.
Get started
Create a free key at eulerpool.com/developers/register — no credit card, 10,000 requests/month. Then read the dark pool data API MCP docs and ship.
Every day’s drop is listed on the Financial Data API changelog. Same data powers the Eulerpool terminal 500,000+ investors already use — the API is that database with a key in front of it.
