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, etc.) can query market data directly. Useful if you're building LLM-powered trading tools.
This is an early beta. Feedback on API design, missing features, or technical architecture is welcome.
