<p>直近数日の内にSoundCloudはAPIの仕様を変更したようです。自作のTypeScriptコンポーネントがうまく機能しなくなったために対応しました。</p>

<p>以前はiframeのsrcに指定するurlは曲ページへのリンクと同じリンクを指定すればよかった
のですが、ここ数日の変更でiframeのsrcの指定はAPI専用のURLでなければならなく
なったようです。</p>
<p>この変更は既にアップロードされている曲には遡及していないようで、直近にアップ
ロードした曲のみに影響しています。</p>
<h2 id="SoundCloudEmbed_コンポーネントの変更">SoundCloudEmbed コンポーネントの変更</h2>
<p>本来はSoundCloudでJavascriptのコードを取得すべきです。
このブログではMDXを使っている関係で取得したコードでは修正が必要なため、
<code>SoundCloudEmbed</code>というコンポーネントを作っていました。
この変更でShare Linkのみ指定していたSoundCloudEmbedは動かなくなりました。</p>
<p>仕方がないのでAPI用のURLを指定できようように修正しました。またタイトルの固定
でなく曲名を指定できるよう変更しています。</p>

<p>API用URLだけ取得はできないので、結局埋め込み用のJavascriptのコードをSoundCloudから取得してURLを取り出して貼り付けることになります。
手間は貼り付けるより面倒なので、コンポーネントにした意味がないかもしれません。</p>
直近数日の内にSoundCloudはAPIの仕様を変更したようです。自作のTypeScriptコンポーネントがうまく機能しなくなったために対応しました。
国税庁の法人番号システムWeb-APIの検証

<p>仕事で企業を一意に特定するという要件があり、法人番号制度を利用するために
国税庁が提供する法人番号システムのWeb API
の検証のためのコードを作成してみました。</p>
<h2 id="法人番号制度とは">法人番号制度とは</h2>
<p>法人番号制度は、2015年10月5日に発足しました。
この制度は、行政の効率化、国民の利便性の向上、および公平・公正な社会の実現を
目的として導入されました。法人には13桁の番号が指定され、商号や所在地といった
基本情報とともに国税庁の法人番号公表サイトで公開されています。</p>
<p>特に近年では、2023年10月から開始されたインボイス制度（適格請求書等保存方式）
との関連で、登録番号（T+法人番号等）を記載した適格請求書の発行が消費税の
仕入税額控除の要件となっているためシステムで扱うことも多くなっています。</p>
<h2 id="国税庁のWeb_APIについて">国税庁のWeb APIについて</h2>
<p>国税庁が提供するAPIについては、<a rel="external" href="https://www.houjin-bangou.nta.go.jp/webapi/index.html">法人番号システムのWep API</a>
のページに利用方法や申し込み方法がガイドされています。</p>
<p>利用には国税庁が振り出す「アプリケーションID」を取得する必要があります。
次の２つのアプリケーションIDがあります。</p>
<ul>
<li>インボイスWeb-APIを利用できるアプリケーションID</li>
<li>法人番号システムWeb-APIのみ利用できるアプリケーションID</li>
</ul>
<p>前者は国税庁の承認を受ける必要がありますが、後者の法人番号システムのAPIにつ
いては申請だけでアプリケーションIDを振り出してくれます。ただし、申請してから
２週間から1ヶ月程度かかります。</p>
<h2 id="法人情報検索APIクライアント">法人情報検索APIクライアント</h2>
<p>Typescriptで検証のためのコードを書いてみました。</p>
<p>法人名、または法人番号で検索できます。</p>
<p>実行すると、次のような標準出力にレスポンスをそのまま表示します。
(以下の例では、適当に折り返しています)</p>
<p><a rel="external" href="https://github.com/yostos/get-company-info">GitHubに公開</a>したので、ビルド方法や詳細な使い方はそちらをご覧ください。
検証用なのでエラー処理はいい加減です。</p>
