Questions & Answers

As answered by people managing Codewars and SiftingIO.

Which are the primary technologies used for building your product?

SiftingIO's answer:

SiftingIO is built on a modern API and data infrastructure for real-time and historical market data delivery.

The platform uses technologies and engineering patterns around:

  • REST APIs for snapshots, historical data, and reference data
  • WebSocket streams for live market data updates
  • Cloud infrastructure for scalable API delivery
  • Multi-region architecture for reliability
  • API authentication and scoped access control
  • Market data normalization and schema design
  • Data aggregation and de-duplication pipelines
  • Historical time-series storage and retrieval
  • SDKs and developer tooling for integration workflows

The focus is on building a reliable data infrastructure that can serve financial applications, dashboards, trading tools, research systems, and enterprise workflows.

What makes your product unique?

SiftingIO's answer:

SiftingIO is built around a simple idea: market data should be easier to integrate, but not simplified to the point where it becomes unreliable.

The platform combines real-time and historical data across multiple asset classes under one API structure. Teams can work with stocks, FX, crypto, commodities, DEX, and on-chain markets without maintaining separate schemas, authentication models, and integration logic for each source.

What makes SiftingIO different is the engineering layer behind the API:

  • Unified JSON schemas across supported asset classes
  • REST and WebSocket access from the same product family
  • Multi-venue aggregation and normalization
  • Historical and real-time workflows in one platform
  • API design focused on consistency, versioning, and maintainability

This makes SiftingIO useful for teams that care not only about accessing data, but also about keeping their data infrastructure clean and scalable.

Why should a person choose your product over its competitors?

SiftingIO's answer:

SiftingIO is a strong choice for teams that need market data across more than one asset class and want to avoid maintaining multiple vendor integrations.

Many financial applications start with one market, then expand into others. A team may begin with FX or crypto, then later need stocks, commodities, DEX data, or on-chain metrics. SiftingIO is designed for that kind of growth.

Key reasons to choose SiftingIO:

  • One API structure across supported markets
  • Real-time and historical data workflows
  • REST snapshots and WebSocket streams
  • Unified schemas that reduce integration complexity
  • Multi-venue aggregated and normalized data
  • Developer resources including documentation, SDKs, and Postman examples
  • Enterprise-ready options such as SLA-backed plans, DPA, invoicing, and dedicated support

The main value is not only data access. It is reducing the engineering cost of using market data across financial products.

How would you describe the primary audience of your product?

SiftingIO's answer:

SiftingIO is built for technical and data-driven teams working with financial market data.

The primary audience includes:

  • Developers building financial applications
  • Fintech teams integrating market data into products
  • Trading tool providers
  • Dashboard and analytics platforms
  • Quantitative research teams
  • Backtesting and data science workflows
  • Enterprise data teams that need API-based market data delivery

SiftingIO is especially useful for teams that need both real-time and historical data, or teams that work across multiple asset classes and want a consistent API model instead of separate vendor-specific integrations.

What's the story behind your product?

SiftingIO's answer:

SiftingIO was created from hands-on experience building and operating financial data infrastructure.

Market data integrations often become more complex as products grow. Each asset class can come with different data formats, different delivery methods, different authentication models, and different assumptions about symbols, timestamps, quotes, trades, and history.

SiftingIO was built to reduce that complexity.

The goal is to provide a consistent market data API that helps teams access real-time and historical data across multiple asset classes without rebuilding their integration every time they add a new market.

The product reflects an engineering-first approach: clean API design, unified schemas, REST and WebSocket support, multi-venue aggregation, and infrastructure that can support production financial workflows.

Who are some of the biggest customers of your product?

SiftingIO's answer:

SiftingIO does not publicly list customer names unless they are approved for disclosure.

The platform is designed for financial applications, trading tools, dashboards, research platforms, quantitative teams, fintech companies, and enterprise data workflows that need real-time or historical market data through APIs.
