Infrastructure You Can Trust

Purpose-built from the ground up for financial-grade data delivery.

gRPC Streaming

Server-side streaming via Connect RPC delivers trades with minimal overhead. Binary Protocol Buffers keep payloads small and parsing instant.

Precision-First Math

Zero floating-point operations on financial data. Prices and quantities use string serialization backed by arbitrary-precision integer arithmetic.

Smart Filtering

Subscribe only to what you need. Server-side pair and source filtering reduces bandwidth by up to 95% compared to unfiltered firehose feeds.

Auto-Recovery

State machine lifecycle management with infinite retry and automatic reconnection. Exchange disconnections are handled transparently — your stream stays alive.

Complete Market Picture

Every trade, every exchange, zero gaps. Deduplication and sequencing ensure you never miss a fill or process a duplicate — giving you the full, accurate view.

99.99% Uptime SLA

Redundant ingestion across all exchanges with automatic failover. If an exchange drops, your stream continues from the remaining sources — uninterrupted.

Train on History. Trade the Future.

Comprehensive historical market data, cleaned and normalized for quantitative research and machine learning pipelines.

Frequently Asked Questions

Everything you need to know about Arcfeed's market data infrastructure.

We currently support 10 major exchanges: Binance, Bitfinex, Bitstamp, Bybit, Coinbase, Gemini, Huobi, Kraken, KuCoin, and OKX. We actively accept requests to add new exchanges — if there's an exchange you need, let us know and we'll prioritize it.

Our real-time stream delivers trade data with sub-200ms end-to-end latency (P95). Data flows from exchange WebSocket to your application through our optimized pipeline: Exchange → Ingest → Normalize → Filter → Deliver. We discard trades older than 1 second to ensure data freshness.

All data is delivered via gRPC streaming using Protocol Buffers for maximum efficiency. Each trade includes source exchange, market pair, price, quantity, and nanosecond-precision timestamps. Prices and quantities are transmitted as strings to preserve full decimal precision — we never use floating-point for financial data.

Yes. We maintain 29B+ historical trades spanning 2+ years across all supported exchanges. That's 5.27TB of cleaned, normalized, and deduplicated data ready for backtesting, model training, and market research. For ML workloads, we also offer direct BigQuery access — query the full dataset with standard SQL in your own GCP project.

We use JWT-based authentication. Once onboarded, you'll receive API credentials that you include in your gRPC connection metadata. Tokens are managed securely and can be rotated at any time. Contact us to get started.

Our infrastructure runs on Google Cloud with multi-region deployment for maximum reliability. We offer 99.9%+ uptime with custom SLA options available — contact us to discuss your specific reliability requirements.

Absolutely. Server-side filtering lets you subscribe to specific exchange sources and market pairs. You only receive the data you need, reducing bandwidth and processing overhead on your end.

We provide SDKs for Go, Python, and TypeScript. Since our API uses gRPC/Connect, you can generate client code for any language that supports Protocol Buffers, including Java, C++, Rust, and more.
