Create chat completion

post
https://api.macpaw.com/ai/api/v1/chat/completions

Creates a model response for the given chat conversation using the same interface as the OpenAI Chat Completions API. Supports both streaming (when stream: true, response is text/event-stream Server-Sent Events) and non-streaming modes. Request and response formats follow the OpenAI Create chat completion API. Prefer the Responses API for new integrations; this endpoint is maintained for backward compatibility.
