Historical Market Data API

WideSurf API Platform is a production-grade stock market data service designed as a scalable alternative to platforms like www.alpaca.markets. Built with modern cloud-native architecture and deployed on Kubernetes (K3s), it delivers high-performance financial data APIs alongside a polished, user-friendly dashboard.

Features:

• K3s Kubernetes
• 12000+ stocks
• 6+ billion records

At its core, WideSurf provides a robust REST API for accessing U.S. equity market data, including tickers, OHLC aggregates, market snapshots, and dividend information. The backend is powered by FastAPI and optimized for time-series workloads using ClickHouse, with Redis handling caching and rate limiting, and MinIO providing S3-compatible object storage for downloaded datasets.

The platform includes a modern Next.js 14 frontend featuring a glassmorphism-style UI, interactive TradingView-compatible charts, and detailed stock views. An integrated admin panel enables API key management, usage analytics, and account configuration, making the platform suitable for both internal teams and external API consumers.

WideSurf is fully containerized and orchestrated with K3s, using Traefik for ingress and Let’s Encrypt for SSL. Deployment is streamlined through Kubernetes manifests and a single deployment script, enabling fast, repeatable rollouts across environments. Built-in Swagger/OpenAPI documentation ensures developers can quickly integrate and test endpoints.

Overall, WideSurf API Platform demonstrates a complete, end-to-end financial data infrastructure: from data ingestion and storage, to scalable API delivery, to a production-ready UI and admin experience—engineered for performance, reliability, and extensibility.
