# API Limits

To ensure fair resource allocation and prevent malicious attacks, we implement rate limiting based on the cumulative recharge amount of the account. The details are as follows. 

| Tier          | Cumulative Recharge Amount | QPS | QPM  | QPD    |
| ------------- | -------------------------- | --- | ---- | ------ |
| **Free Tier** | $0                         | 1   | 60   | 1000   |
| **Tier 1**    | $10\~50                    | 5   | 200  | 2000   |
| **Tier 2**    | $100                       | 10  | 500  | 10000  |
| **Tier 3**    | $500                       | 30  | 2000 | 100000 |
