# WHATPORT(8194)

## NAME

port 8194 — Bloomberg data API (blp1) — The Bloomberg API port — where blpapi clients connect for market data.

Protocol: TCP  
IANA: blp1

## DESCRIPTION

IANA registers 8194 on TCP and UDP as blp1, "Bloomberg data API", assigned to Bloomberg in 2006. Applications using the Bloomberg API library open a session to this port, either against the local Bloomberg Terminal process on the same workstation or against a B-PIPE/Server API appliance inside the firm. On a scan it identifies a finance desktop or a market-data server, not a general-purpose service. Access is bound to Bloomberg's own licensing and entitlement, so an open socket is not by itself usable data.

## EXPOSURE

**Do not expose.** This is an entitled market-data feed inside a licensed environment; it belongs on the internal network and never on a public interface.

## CHECK

```sh
nc -vz TARGET 8194
```
