How to integrate Market Data BM&FBOVESPA through REST web services (XML or JSON)

Leia este artigo também em Português. Since the beginning of the BM&FBOVESPA “electronification” with DMA technology, it has become increasingly necessary to supply services, systems and portals with product data in the BM&FBOVESPA trading environment. We talked about it on InfoMoney. In this sense, Cedro offers real-time market data services from BM&FBOVESPA on streaming (Crystal Data Feed), disseminated through our CMP protocol (Cedro Message Protocol) and also through a REST service bus (web API/webservices), with XML or JSON response – known as Web Feeder.

The Web Feeder solution implements the REST standard, and third-party solutions can interact and exchange data over XML or JSON. To join, please request a demo account here (or contact comercial@cedrotech.com). You´ll receive access data and documentation to connect.

The Web Feeder Market Data services allows you to:

  • Check real-time or delayed-stock quotes for BOVESPA and BM&F markets
  • Check rates, indicators and currencies quotes
  • Times & Trades for BOVESPA and BM&F markets
  • Lower Highs and Higher Lows for BOVESPA market

Here is an example of how to get quotes for a particular asset:

By default, response is on JSON format. If you want XML format, just add the XML parameter:
