Real, runnable trading tools that plug into CryptoDataAPI — a perp backtester that refuses lookahead, a strategy wiki-brain your agent reads over MCP, and whatever you ship next. Every one is free and open source: clone it, read it, or bend it into your own thing.
Each one runs on live CryptoDataAPI endpoints — the endpoints each app actually calls are listed on its card, so you can see what a key needs to cover before you clone it.
Backtest perp strategies on real Hyperliquid data — honest fees, no lookahead.
An open-source Python engine for backtesting crypto perpetual-futures strategies on real Hyperliquid market data. It charges taker fees on both sides, accrues funding per bar and checks liquidations, so a result you like is a result you could have traded. Every run exports an interactive HTML replay that plays the backtest back bar-by-bar.

An LLM wiki-brain of ~4,900 linked nodes your agent reads over MCP.
An open-source, expert-curated knowledge base of interlinked markdown nodes — strategies, concepts, assets and market narratives — served to AI agents over a local MCP server. Point an agent at it and it can compose trading strategies from real primitives instead of inventing them, grounded on live CryptoDataAPI market data.

REST over 190+ endpoints, or connect an agent directly with the MCP server. Start from the API docs or a library prompt.
Submit it below. If it's useful and it works, we'll feature it here and link it from the docs — no fee, no exclusivity, keep your own license.
Built something on CryptoDataAPI? Send it over. We review every submission by hand — we'll actually open the repo and run it — and email you either way. Open source isn't required, but a link we can inspect is.
