Pack tiers and exact credit values are subject to change; the current authoritative pricing is rendered at https://uapis.cn/pricing. Credits never expire. If there is a payment or usage problem, open a support request at https://uapis.cn/help and we will handle refund requests case by case.

## Limits

Free-tier traffic is bounded by per-IP and per-key rate limits documented at https://uapis.cn/docs/getting-started/fair-use-and-rate-limiting. Buying a pack raises both burst and sustained limits proportional to the pack tier.

Rate-limit state is exposed through these response headers:

- `RateLimit-Policy` — aggregated quota/rate policy entries
- `RateLimit` — aggregated remaining-quota entries
- `X-RateLimit-Limit`, `X-RateLimit-Remaining` — legacy single-value views
- `Retry-After` (set on 429)

1. Open https://uapis.cn/pricing.
2. Choose the credit pack you want to buy.
