crypto-price-data-guide skillA

crypto-price-data-guide is agent-read markdown (skill) from nirholas/three.ws: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
