How cryptocurrency prices work — the complete data pipeline from CEX order books and DEX pools through oracle networks to aggregators. Covers free API alternatives to CoinGecko, VWAP/TWAP calculations, and building price feeds without paid APIs. Use when explaining price sources, building market data features, or comparing data providers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add nirholas/three.ws/crypto-price-data-guide@sha256:bf4159f19cb86780The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
