DTN ProphetX® Web Services

Overview

ProphetX Web Services, in short PXWeb, provides the facility to access real time quotes and historical market information from most modern programming languages using mechanisms based on Web Services standards.

Although PXWeb usually returns an XML result, it is possible to request for the response to be generated as a simple HTML table fragment that can be easily embedded into a web page.  Other possible formats for the result include CSV and JSON.

The purpose of this site is to provide enough information to access PXWeb and some guidelines about the use.  This site offers:

  • Documentation to access the PXWeb operations.
  • A basic user interface that helps to understand the PXWeb operations by doing manual invocation.
  • Simple code samples to help in the preparation of a client program that access PXWeb.

It is important to differentiate between PXWebDoc (this site) and the URLs used to access the actual ProphetX Web Services, which are documented in the connectivity overview section.  PXWebDoc is just a documentation site with some facilities to help in understanding how to use the service.
