### Launch of the Chat API for end-to-end encrypted DMs

Today, we launched the [Chat API](/xchat/introduction) — a new suite of endpoints for building end-to-end encrypted direct messages on X. Message bodies are encrypted and signed on the client; X routes only ciphertext and cannot read plaintext content.

Highlights:
- **[Chat XDK](/xchat/xchat-xdk)** — first-party encryption SDK with support for Python, TypeScript, Rust, Go, C#, and Java. Handles identity and signing keypairs, message encryption/decryption, signing/verification, and optional Juicebox PIN-based private key storage.
- **Conversation and message endpoints** — register and fetch public keys, share conversation keys, list and get threads, send encrypted messages, mark as read, and send typing indicators. See the [Getting Started guide](/xchat/getting-started).
- **Group conversations** — create groups, add members, and rotate conversation keys. See the [Groups guide](/xchat/groups).
- **Encrypted media attachments** — upload and download encrypted images, videos, and files. See the [Media guide](/xchat/media).
- **Real-time delivery** — receive encrypted events via webhooks or activity stream, or replay history via the events API. See [Real-time events](/xchat/real-time-events).

Auth uses OAuth 2.0 user context with DM scopes (`dm.read`, `dm.write`). New to end-to-end encryption? Start with the [Cryptography primer](/xchat/cryptography-primer).

### Lanzamiento de la Chat API para DMs con cifrado de extremo a extremo

Hoy, lanzamos la [Chat API](/xchat/introduction): un nuevo conjunto de endpoints para crear mensajes directos con cifrado de extremo a extremo en X. Los cuerpos de los mensajes se cifran y firman en el cliente; X solo enruta el texto cifrado y no puede leer el contenido en texto plano.

Destacado:
- **[Chat XDK](/xchat/xchat-xdk)**: SDK de cifrado propio con soporte para Python, TypeScript, Rust, Go, C# y Java. Gestiona pares de claves de identidad y firma, cifrado/descifrado de mensajes, firma/verificación y almacenamiento opcional de claves privadas basado en PIN mediante Juicebox.
- **Endpoints de conversación y mensajes**: registra y consulta claves públicas, comparte claves de conversación, lista y consulta hilos, envía mensajes cifrados, marca como leído y envía indicadores de escritura. Consulta la [Guía de inicio](/xchat/getting-started).
- **Conversaciones grupales**: crea grupos, agrega miembros y rota claves de conversación. Consulta la [Guía de grupos](/xchat/groups).
- **Adjuntos multimedia cifrados**: sube y descarga imágenes, videos y archivos cifrados. Consulta la [Guía de medios](/xchat/media).
- **Entrega en tiempo real**: recibe eventos cifrados vía webhooks o activity stream, o reproduce el historial mediante la events API. Consulta [Eventos en tiempo real](/xchat/real-time-events).

La autenticación usa OAuth 2.0 con contexto de usuario y los scopes de DM (`dm.read`, `dm.write`). ¿Nuevo en el cifrado de extremo a extremo? Comienza con el [Manual de criptografía](/xchat/cryptography-primer).

### エンドツーエンド暗号化 DM 向けの Chat API を提供開始

本日、[Chat API](/xchat/introduction) を提供開始しました。X 上でエンドツーエンドで暗号化されたダイレクトメッセージを構築するための新しいエンドポイント群です。メッセージ本文はクライアント側で暗号化・署名され、X は暗号文のみを中継し、平文コンテンツを読み取ることはできません。

主なポイント:
- **[Chat XDK](/xchat/xchat-xdk)**: Python、TypeScript、Rust、Go、C#、Java に対応する、当社提供の暗号化 SDK。ID 用および署名用のキーペア生成、メッセージの暗号化・復号、署名・検証、任意で Juicebox による PIN ベースの秘密鍵保管に対応します。
- **会話およびメッセージ用エンドポイント**: 公開鍵の登録・取得、会話鍵の共有、スレッドの一覧取得・参照、暗号化メッセージの送信、既読の設定、タイピングインジケーターの送信が可能です。[Getting Started ガイド](/xchat/getting-started)を参照してください。
- **グループ会話**: グループの作成、メンバーの追加、会話鍵のローテーションに対応します。[Groups ガイド](/xchat/groups)を参照してください。
- **暗号化されたメディア添付**: 暗号化された画像、動画、ファイルのアップロードおよびダウンロードが可能です。[Media ガイド](/xchat/media)を参照してください。
- **リアルタイム配信**: webhooks または activity stream 経由で暗号化イベントを受信できます。events API 経由で履歴を再取得することもできます。[Real-time events](/xchat/real-time-events) を参照してください。

認証には OAuth 2.0 のユーザーコンテキストと DM 系スコープ(`dm.read`、`dm.write`)を使用します。エンドツーエンド暗号化を初めて扱う場合は、[Cryptography primer](/xchat/cryptography-primer) から始めてください。

### 종단 간 암호화 DM을 위한 Chat API 출시

오늘, [Chat API](/xchat/introduction)를 출시했습니다. X에서 종단 간 암호화 다이렉트 메시지를 구축할 수 있는 새로운 엔드포인트 모음입니다. 메시지 본문은 클라이언트에서 암호화되고 서명되며, X는 암호문만 전달하고 평문 내용은 읽을 수 없습니다.

주요 내용:
- **[Chat XDK](/xchat/xchat-xdk)**: Python, TypeScript, Rust, Go, C#, Java를 지원하는 자체 암호화 SDK. 신원 및 서명 키 쌍, 메시지 암호화/복호화, 서명/검증, 그리고 Juicebox 기반 PIN 방식의 프라이빗 키 저장(선택 사항)을 처리합니다.
- **대화 및 메시지 엔드포인트**: 공개 키 등록 및 조회, 대화 키 공유, 스레드 목록 및 조회, 암호화된 메시지 전송, 읽음 표시, 입력 중 표시 전송을 지원합니다. [시작하기 가이드](/xchat/getting-started)를 참조하세요.
- **그룹 대화**: 그룹 생성, 멤버 추가, 대화 키 로테이션을 지원합니다. [Groups 가이드](/xchat/groups)를 참조하세요.
- **암호화된 미디어 첨부**: 암호화된 이미지, 동영상, 파일을 업로드하고 다운로드합니다. [Media 가이드](/xchat/media)를 참조하세요.
- **실시간 전송**: 웹훅 또는 activity stream을 통해 암호화된 이벤트를 수신하거나 events API로 이력을 재생합니다. [실시간 이벤트](/xchat/real-time-events)를 참조하세요.

인증은 OAuth 2.0 사용자 컨텍스트와 DM 스코프(`dm.read`, `dm.write`)를 사용합니다. 종단 간 암호화가 처음이신가요? [Cryptography primer](/xchat/cryptography-primer)부터 시작하세요.

### Lançamento da Chat API para DMs com criptografia de ponta a ponta

Hoje, lançamos a [Chat API](/xchat/introduction): um novo conjunto de endpoints para criar mensagens diretas com criptografia de ponta a ponta no X. Os corpos das mensagens são criptografados e assinados no cliente; o X apenas encaminha o texto cifrado e não consegue ler o conteúdo em texto simples.

Destaques:
- **[Chat XDK](/xchat/xchat-xdk)**: SDK de criptografia próprio, com suporte a Python, TypeScript, Rust, Go, C# e Java. Cuida dos pares de chaves de identidade e assinatura, criptografia/descriptografia de mensagens, assinatura/verificação e armazenamento opcional de chaves privadas baseado em PIN via Juicebox.
- **Endpoints de conversas e mensagens**: registre e consulte chaves públicas, compartilhe chaves de conversa, liste e obtenha threads, envie mensagens criptografadas, marque como lidas e envie indicadores de digitação. Consulte o [Guia de introdução](/xchat/getting-started).
- **Conversas em grupo**: crie grupos, adicione membros e rotacione chaves de conversa. Consulte o [Guia de grupos](/xchat/groups).
- **Anexos de mídia criptografados**: envie e baixe imagens, vídeos e arquivos criptografados. Consulte o [Guia de mídia](/xchat/media).
- **Entrega em tempo real**: receba eventos criptografados via webhooks ou activity stream, ou recupere o histórico pela events API. Consulte [Eventos em tempo real](/xchat/real-time-events).

A autenticação usa OAuth 2.0 com contexto de usuário e os escopos de DM (`dm.read`, `dm.write`). Novo em criptografia de ponta a ponta? Comece pelo [Guia de criptografia](/xchat/cryptography-primer).
