❓ FAQ

How does the credit system work? ▼

Credits are the universal currency for API calls: 1 credit = 1 API call. Pay once and credits are added to your account — they never expire and there are no monthly fees. All plans are priced and settled in CNY (¥) via WeChat Pay / Alipay; any USD figure shown is an indicative conversion, not a separate SKU.

1 积分 = 1 次 API 调用？积分会过期吗？ ▼

是的，1 积分 = 1 次 API 调用。积分永久有效，无月费，不按月订阅。一次性付费，用完为止。三档统一为：Starter 100 积分 ¥9、Pro 500 积分 ¥29、Lifetime 无限 ¥199（均以人民币结算）。

What counts as an API call? ▼

Each HTTP request to any /api/ endpoint counts as one call and consumes 1 credit. A single /api/data.json request returns all data in one call.

Do you offer monthly subscriptions? ▼

No. We use a one-time credit model — pay once and credits never expire. No recurring charges, no monthly fees. Visit credits to top up.

Can I use the data commercially? ▼

Free sign-up credits are for personal/educational use. Pro and Lifetime plans include a commercial use license. Data packages include commercial rights.

How often is the data updated? ▼

Continuously, not on a fixed schedule. Every response carries meta.last_updated and meta.total_entities so you can detect changes yourself; the OSS layer additionally exposes its own generation timestamp at /api/oss?stats=1. There is no push/webhook notification for data updates yet — poll meta.last_updated instead.

What payment methods do you accept? ▼

WeChat Pay and Alipay (QR code, CNY settlement) — this is currently the only self-serve checkout. We do not accept credit cards, PayPal or crypto at the moment. If you are outside China and cannot use WeChat/Alipay, email 61960005@qq.com and we will issue the credits manually against a bank transfer — we would rather tell you this up front than send you to a checkout that fails.
