  • 900+ unit tests — Comprehensive coverage across all exchange parsers, indicators, cache, and integration tests
  • ETF flow data — BTC & ETH spot ETF daily flows, AUM, and holdings via SoSoValue
  • Exchange reserves — CEX reserve balances via DefiLlama for 14 exchanges

Quick Start

# Clone and build
git clone https://github.com/alt0x17/crypton
cd crypton
cargo build --release

# Run (default port 3177)
./target/release/crypton

# Test it
curl http://localhost:3177/v1/overview?symbol=BTC
REST endpoints require no authentication. WebSocket connections require a token (?token=secret). All REST responses are gzip-compressed and wrapped in {status, timestamp, data} envelope.
