When your data needs outgrow the API layer
Some systems need the data before it reaches the API layer.
When your data needs outgrow the API layer
Some systems need the data before it reaches the API layer.
REST and WebSocket APIs make it easy to get started with market data. They work well for a lot of use cases. But some systems have requirements that push past what that model can support. If you need full exchange coverage, direct transport protocols, or infrastructure built for continuous high-throughput ingestion, you may be looking at the wrong layer. NxCore is built for that next layer.

NxCore vs Aggregated Data APIs
Aggregated Data APIs
WHERE AGGREGATED APIS WORK WELL
They are quick to integrate and easy to work with. For dashboards, research tools, and analytics workflows that do not need tick-level delivery, they are often the right call. Tiered pricing means teams can get started without a large commitment.
WHERE NXCORE IS A BETTER FIT
- You need continuous tick-level delivery, not a request-response cycle
- Your system ingests the full exchange feed at high throughput
- Your team owns the data pipeline from the transport layer up
- HTTP overhead is introducing latency your strategy cannot absorb
NXCORE ADVANTAGE
NxCore delivers raw binary market data over UDP/TCP. It is built for teams working at the infrastructure layer, not the API layer.
