BlackForge is market data for the crypto spot market, built from the order book up. We record the full order book and every trade on the major exchanges, across 14,000+ pairs, and turn them into 150+ live measurements per pair: depth near the price, walls, liquidity added and pulled, the real cost of a market order, taker buying and selling, trade sizes, sweeps and more. The history is kept, so you can go back to any moment. Use it from the dashboard, through the API, from the command line, or directly inside AI agents like Claude through our MCP server. Built for traders, quants, researchers and developers who need to see what the book is really doing, not just the last price. blackforge.so
