YuzucaPublicClient（客户端 API 客户端）

import { YuzucaPublicClient, createHmacSignatureProvider } from "@yuzuca/sdk";

const client = new YuzucaPublicClient({
  apiKey: "yzpub_xxx",
  serverUrl: "https://your-server.example.com",
  signatureProvider: createHmacSignatureProvider("public-signing-secret"),
});

apiKey 为客户端 API Key（Public API Key）；signatureProvider 为可选签名器，用于启用请求签名。

登录与令牌：

await client.login({ type: "email", value: "user@example.com" }, "password");
const profile = await client.me.get();
await client.refresh();
await client.logout();

login 成功后会写入访问令牌和刷新令牌，后续请求自动携带。

客户自助能力：

• client.subscriptions.list()
• client.subscriptions.getUsages(subscriptionId)
• client.licenseCodes.list()
• client.redemptions.redeem({ code })
• client.entitlements.check(...)
