If you need public data from multiple cryptocurrency exchanges but don't want to deal with weird differences in exchange APIs, Blocktap[1] is a free GraphQL API (that I assisted in developing). We also open sourced our web socket data collection tool CCXWS[2]. It's a single, consistent Javascript API for most major exchanges.

Agreed very much. I want to add that Bitfinex is making huge parts of their code open source: https://github.com/bitfinexcom/

Paolo Ardoino (CTO) basically pushes code every day: https://github.com/prdn

You may be interested in an existing commercial offer of non native bitmex api, with guaranteed latency and a few other bells n whistles.

Want to know more?

Can you point me to the $1k limit?

Time passed since then, but this is it: https://www.bitfinex.com/posts/243 I don’t remember dates exactly, maybe we entered with $10k even, because I worked with it around Mar 2018.
