Direct binary feed vs REST-based market data delivery

Your infrastructure layer and your API layer are not the same thing.

REST APIs have made market data accessible to more developers than ever. For many applications, they are the right choice. NxCore is designed for a different situation. If your system needs data delivered as a continuous binary stream over UDP/TCP rather than pulled via HTTP, you are looking at a different infrastructure layer. Both models are used in production. The question is which one fits your architecture.

HOW THEY COMPARE

NxCore vs REST-based Delivery

Feature

  • Transport

  • Delivery

  • Latency

  • Scalability

  • Setup

NxCore

  • UDP/TCP binary stream

  • Continuous push

  • Tick-level (verify internally)

  • Infrastructure-grade throughput

  • Feed handler required

Cloud REST Data APIs

  • HTTP REST request-response

  • Client-initiated request

  • HTTP round-trip overhead

  • Rate-limited by plan tier

  • Standard HTTP client

WHERE REST APIS WORK WELL

Low barrier to integration. Any language with an HTTP client can connect. REST suits dashboards, reporting tools, and applications that pull data on demand. The ecosystem is mature and authentication is straightforward.

WHERE NXCORE IS A BETTER FIT

  • Your system needs continuous delivery without polling
  • HTTP round-trip latency is incompatible with your requirements
  • Your throughput needs exceed what REST plan tiers can sustain
  • You are building your own feed handler and normalisation layer

NXCORE ADVANTAGE

NxCore operates at the feed layer. It is for systems where continuous binary delivery over UDP/TCP is the right architectural choice.
