Rate Limits
To protect service availability and prevent abuse, Tiger OpenAPI applies rate limits to all API requests.
Rate Limiting Rules
Rate limits are applied at the tigerId + method level, meaning each tigerId has an independent quota for each API method. For example, calls to place_order and get_orders under the same tigerId are counted separately and do not affect each other.
API methods are classified into three tiers based on allowed call frequency:
| Tier | Rate Limit | Counting Method |
|---|---|---|
| High-frequency | 120 calls/min | Per tigerId and method, 60-second rolling window |
| Medium-frequency | 60 calls/min | Per tigerId and method, 60-second rolling window |
| Low-frequency | 10 calls/min | Per tigerId and method, 60-second rolling window |
A documented rate-limit response example is shown below:
code=4 msg=rate limit error(current limiting interface:<interface_name>, up to 60 times per minute)The application code in existing documentation is inconsistent: this example uses code 4, while the error-code table assigns rate limiting to code 5. Until the service contract is confirmed, detect HTTP 429 and use the returned limit description rather than depending on one application code.
NOTE
- If you repeatedly exceed a rate limit, the system may automatically blacklist the account. A blacklisted account cannot make further API requests.
- To increase your rate limits, sign in to the Developer Center and purchase a higher limit.
