//
// TODO(zai): fill in the real fetch. Options:
//   (a) shell out to a CLI (like minimax does with `mmx`) if one exists
//   (b) read the API key from env (ZAI_API_KEY / ZHIPUAI_API_KEY) and
//       call the billing/quota endpoint directly via fetch()
// The shape below is the contract — replace the body of fetch().
