× 公式価格 = 換算価格 ÷ 同じモデル・同じ仕様の最安の公式価格。~ は緩い一致を示します:どちらか一方でティア、解像度、音声の有無が明記されておらず、対応しうる公式仕様がすべて同じ価格の場合です。— = 明確に比較できる公式価格がありません。

信頼度:「料金ページ」= プロバイダー自身の料金ページまたはドキュメントで確認、「料金 API」= 公開 API のレスポンスから取得。「BYO」ティアは自前アカウント持ち込みの概算で、1回あたりの価格ではありません。

確認日:各価格に添えた日付は、その価格を最後に確認した日です。直近の更新日()より 7 日を超えて古い日付はオレンジ色で表示します。
