  description: 'Keywords AI is an LLM observability and gateway platform. This specification documents the publicly documented REST surface served from https://api.keywordsai.co/api: the OpenAI-compatible chat completions proxy, the asynchronous request-logging endpoint, prompt and prompt-version management, threads, traces, evaluators, users (customers), datasets, and experiments. All endpoints authenticate with a Bearer API key. (Keywords AI is rebranding to Respan; the keywordsai.co host and API remain active.)'
