cn-cloud-billing

One typed API for Alibaba Cloud, Tencent Cloud and Volcano Engine monthly bills.

Each Chinese cloud ships its own billing API with different auth, shapes, pagination and quirks. cn-cloud-billing puts all three behind a single call and hands you normalized rows — monthly totals by product, or per-resource detail with region and resource id. Bring your own access keys; it imposes no categorization or cost attribution — just the numbers, normalized.

npm i cn-cloud-billing

Quick start

import { CnBilling } from "cn-cloud-billing";

const billing = new CnBilling({
  aliyun:  { accessKeyId: process.env.ALI_AK!,   accessKeySecret: process.env.ALI_SK! },
  tencent: { secretId:    process.env.TC_ID!,    secretKey:       process.env.TC_KEY! },
  volcano: { accessKeyId: process.env.VOLC_AK!,  secretAccessKey: process.env.VOLC_SK! },
});

// Monthly totals by product, across all three clouds:
const summary = await billing.getMonthlySummary("2026-05");
// → [{ provider: "aliyun", month: "2026-05", product: "ECS", amount: 1234.5, currency: "CNY" }, ...]

// Per-resource detail (region + resourceId where the API exposes them):
const detail = await billing.getMonthlyDetail("2026-05");
// → [{ provider: "volcano", month: "2026-05", product: "GPU_Server",
//      region: "cn-beijing", resourceId: "i-abc…", amount: 88.0, currency: "CNY" }, ...]

Query one cloud in isolation:

const rows = await billing.provider("tencent").getMonthlyDetail("2026-05");

Normalized shape

Every row is a BillRow:

interface BillRow {
  provider: "aliyun" | "tencent" | "volcano";
  month: string;        // "YYYY-MM"
  product: string;      // provider's product / business name
  region?: string;      // detail only
  resourceId?: string;  // detail only
  amount: number;       // payable / real cost in `currency`
  currency: string;     // e.g. "CNY"
  raw?: unknown;        // original provider line, with { includeRaw: true }
}

amount maps to each provider's payable cost — Aliyun PretaxAmount, Tencent ΣComponentSet.RealCost, Volcano PayableAmount.

What it handles for you

• Auth & signing — official SDKs for Aliyun/Tencent; Volcano is driven through @volcengine/openapi's signer (no maintained Node billing SDK exists).
• Pagination — Aliyun NextToken, Tencent Offset, Volcano Offset (including the case where Volcano returns Total = -1 and you must stop on a short page).
• Quirks — Volcano detail needs GroupPeriod = 1; Tencent detail cost is the sum of a row's ComponentSet.

Credentials

Provider	Fields	Needs
aliyun	accessKeyId, accessKeySecret	BssOpenApi read access
tencent	secretId, secretKey	DescribeBillSummaryByProduct / DescribeBillDetail
volcano	accessKeyId, secretAccessKey	ListBillOverviewByProd / ListBillDetail

Configure only the clouds you use — pass one, two, or all three.

Notes

• Amounts are in each account's settlement currency (typically CNY); this library does no FX conversion (pair it with monthly-fx if you need USD).
• This is an independent client and is not affiliated with Alibaba, Tencent or Volcano Engine.
