Start here.

Ringside is an OpenAI-compatible API in front of many model providers, with one thing bolted on that nothing else has: it knows about your end-customers and meters spend per customer. That one idea is what most people get stuck on, so this guide builds up to it instead of dropping you in the middle.

Three short pages: make a call work, understand who pays for what, then choose models. After that, the RAG guide covers search-over-documents, the tutorials build whole things end to end, and the API reference has every endpoint.
