# 단기 SIP 토큰 발급 (WebRTC/SIP 단말용)

POST https://api.claw-ops.com/v1/accounts/{accountId}/sip-credentials/{credentialId}/tokens
Content-Type: application/json

영구 SipCredential 로부터 단기 JWT 를 발급. 랜덤 ephemeral SIP username/password 와 함께 발급되며, JWT payload 에 SIP digest 인증에 필요한 모든 값(`ws_url`, `realm`, `sip_username`, `sip_password`, `allowed_caller_ids`)이 포함됨. 클라이언트는 JWT 를 디코드해서 JsSIP/SIP.js 등 SIP UA 에 그대로 사용. 서버측은 이 엔드포인트를 자체 백엔드에서 호출해 결과를 그대로 브라우저에 전달하는 패턴 권장 (API Key 노출 방지). 부모 자격은 `status=active`, `enabled=true` 여야 함.

Reference: https://docs.claw-ops.com/api-레퍼런스/claw-ops-api/web-rtc/create-webrtc-token

## Authentication

- `Authorization` header (bearer token, required) — API Key를 Bearer 토큰으로 전달

## Request

### Path parameters

- `accountId` (string, required)
- `credentialId` (string, required)

### Body (application/json)

- `ttl_seconds` (integer, optional, default: 3600) — 토큰 TTL (초). 1 ~ 86400 (24시간). 권장 5~30분 (통화 1건 길이).
- `subject` (string, optional) — JWT `sub` 클레임. 미지정 시 `user:<parent_credential_id>`. 사용자별 추적/감사용.

## Response

### 201

발급 성공 — JWT + ws_url + sip_uri

- `token` (string, required) — HS256 JWT. payload 클레임: `account_id`, `credential_id` (ephemeral), `parent_credential_id` (영구), `sub`, `sip_username`, `sip_password`, `realm`, `ws_url`, `allowed_caller_ids`, `jti` (= ephemeral credential id), `iat`, `exp`. 클라이언트가 SIP digest 인증(REGISTER/INVITE)에 사용. 서명 검증은 ClawOps 게이트웨이가 수행하므로 클라이언트는 디코드만 하면 됨.
- `token_type` (enum, required)
  - Allowed values: `Bearer`
- `expires_at` (datetime, required) — JWT 만료 시각 (ISO 8601).
- `ws_url` (string, required) — SIP-over-WebSocket 게이트웨이 URL. 클라이언트(JsSIP/SIP.js)가 WSS handshake 대상으로 사용.
- `sip_uri` (string, required) — 발급된 단기 SIP URI (`<ephemeral_username>@<realm>`).
