On-chain crypto charts from its own nodes, plus a free API

See what's really moving Bitcoin, Ethereum and a growing list of coins. Every on-chain chart is calculated from full nodes I run myself, with its method written under it. Free live tools for liquidations, ETF flows and fear & greed, plus a keyless API, Google Sheets and an MCP server for AI assistants.
Hi everyone, I'm the creator of CryptoKeyhole.
I kept hitting the same problem with crypto data: you see a number, but not how it was made. So I run my own full nodes for Bitcoin, Ethereum, Litecoin, Dogecoin and Bitcoin Cash, calculate every on-chain chart from my own copy of the chain, and write the method, sources and limits under each chart. When data is late, the chart says so instead of guessing.
Free, with no account needed:
• Live tools: crypto liquidations today, bitcoin ETF flows, bitcoin and ether funding and open interest, and a Fear & Greed Index for the whole market and each coin
• The free charts with their full history
• A keyless API, plus Google Sheets, Excel and Python
• A read-only MCP server, so AI assistants and agents can read the data directly
Plus and Pro add hourly data, the rest of the charts, more alerts and downloads.
Launch offer for Product Hunt: 50% off the first year of Plus or Pro on a yearly plan with code PRODUCTHUNT, through 10 November (new subscribers; it renews at the normal price after that): https://cryptokeyhole.com/pricin...
Good places to start: the lens over Bitcoin's whole price history on the home page, crypto liquidations today (https://cryptokeyhole.com/crypto...) and the free API (https://cryptokeyhole.com/data-a...).
I'd love to hear which charts or explanations are unclear, and what you'd want me to build next.
