Every exchange that doesn't provide a solid, well maintained API is missing out big time imo.

I'm not just talking about having a fast, reliable API but also
a top tier ecosystem. If you want to gain users faster help people who build stuff around your platform.

1/4

No-Nos for me are

- No well maintained API libs for popular languages
- No proactive support for community made 3rd party libs
- Outdated, incomplete or wrong API docs
- Unclear descriptions in API docs
- Missing API versioning
- Not working or even missing example code

2/4

- No error codes
- Unresponsive support (in github repos)
- A inconsistent API
- Lack of a dedicated notification channel about breaking changes that's not spammed with marketing.
- Unnecessary complicated / abstract example code

3/4

- Absurd API limitations (jfc Bybit!)
- No API at all lmfao

I experienced all of this by now. Probably forgot stuff.
