Backstory: I wanted to play with intraday stock data but couldn't find a free dataset anywhere. IEXCloud [1] offers API access to 1-minute granularity intraday historical price data, but I was worried that it could get expensive or unwieldy to build up a substantial dataset via API calls. Plus, IEX gives out their raw data for free. I probably should have just used the IEXTools python library [2] to parse IEX's raw data dumps, but I was working on a Julia project, so it felt more thematically appropriate to build a new tool from scratch. I haven't been actively using InvestorsExchange.jl a…

The current pricing for crypto data APIs (CoinGecko/CMC) is based on a legacy requirement: maintaining hundreds of real-time websocket connections to centralized exchanges (Binance, Coinbase, Kraken, etc.). That infrastructure is heavy, expensive, and requires constant maintenance to filter wash-trading and normalize order books. But if you are building for DeFi, that data is technically irrelevant. The "real" executable price is on-chain (Uniswap, Raydium, Curve). I realized that if I just ignored the CEXs entirely and only indexed the blockchain, I could drop the cost basis by an…

Luzia normalizes real-time ticker data from Binance, Coinbase, Kraken, Bybit, and OKX through a single REST/Websocket API. Why I built this: Every crypto project I worked on required maintaining separate exchange connectors. Different authentication, different response formats, different error handling. It's repetitive work that doesn't add value to the actual application. Technical details: - Bun runtime with Hono framework - PostgreSQL + Drizzle ORM - Circuit breaker pattern for fault tolerance - BullMQ for background price fetching Also built: An MCP server so AI agents (Claude,…
