Setup

配置步骤

If 
$TRANSCRIPT_API_KEY
is not set, help the user create an account (100 free credits, no card):
Step 1 — Register: Ask user for their email.
bash
node ./scripts/tapi-auth.js register --email USER_EMAIL
→ OTP sent to email. Ask user: "Check your email for a 6-digit verification code."
Step 2 — Verify: Once user provides the OTP:
bash
node ./scripts/tapi-auth.js verify --token TOKEN_FROM_STEP_1 --otp CODE
API key saved to your shell profile and agent config. Ready to use.
Manual option: transcriptapi.com/signup → Dashboard → API Keys.
如果未设置
$TRANSCRIPT_API_KEY
，请帮助用户创建账户（提供100个免费额度，无需绑定银行卡）：
步骤1 — 注册： 向用户索要邮箱地址。
bash
node ./scripts/tapi-auth.js register --email USER_EMAIL
→ 验证码（OTP）将发送至该邮箱。请询问用户：“请查收邮箱中的6位验证码。”
步骤2 — 验证： 用户提供验证码后执行以下命令：
bash
node ./scripts/tapi-auth.js verify --token TOKEN_FROM_STEP_1 --otp CODE
API密钥将保存至你的Shell配置文件和Agent配置中，此时即可开始使用。
手动注册选项：访问transcriptapi.com/signup → 进入控制台 → 获取API密钥。
