OpenAI-compatible Hitch API tools: list models and chat completions via Bearer auth.
Call the Hitch OpenAI-compatible API to list models and create chat completions via Bearer auth. Use when the user wants Hitch/Genoventures models, an OpenAI-compat chat call through Hitch, or to discover available model ids before chatting. Do not invent model ids; list first. Do not use for marketplace publish, modelhitch npm rewrites, or Cloudflare ops.
