EasyAPI の OpenAI 互換 API でこのモデルを呼び出す、コピーして使えるコード。
コンソールで API トークンを作成し、環境変数に設定します:
sk-xxxxxxxx をコンソールで発行した API トークン(Bearer Token)に置き換えてください。
API トークンを作成export EASYAPI_API_KEY=sk-xxxxxxxxモデル ID xai/grok-4.20-reasoning を使って EasyAPI を呼び出します:
curl https://token.easyapi.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $EASYAPI_API_KEY" \
-d '{"model":"xai/grok-4.20-reasoning","messages":[{"role":"user","content":"Hello!"}]}'リクエストボディに "stream": true を追加し、SSE で応答を受け取ります:
curl -N https://token.easyapi.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $EASYAPI_API_KEY" \
-d '{"model":"xai/grok-4.20-reasoning","messages":[{"role":"user","content":"Hello!"}],"stream":true}'チャット補完リクエストを送信します。ストリーミングと非ストリーミングに対応。
