Read list Messages.

Contract-preserving GET Endpoint for list Messages in the OpenAI API. Model and resource-specific values are supplied by the caller at runtime.

All 288 OpenAI Platform REST endpoints from a fixed MIT-licensed official revision, including typed SSE streaming and Realtime call management. Hub provides documentation and an independent SDK/CLI, but never proxies model, account, or usage data; callers connect directly with local API keys.
