API Limits

HyperLiquid enforces limits on the number of API requests.

Key rules:

• Limits are tied to the account, not to a specific API key

• Initial limit after creating an address — 10,000 requests

• The limit grows automatically: 1 request = 1 USDC of actual trading volume (executed orders only)

• When the limit is exhausted, 1 request every 10 seconds is available

• Order cancellations have a separate, higher limit — you can cancel orders even at zero main limit

• Additional requests can be purchased using your HyperLiquid balance

More details: official HyperLiquid documentation

Monitoring limits in the terminal:

MoonTrader displays information about spent and available API requests. To purchase additional requests:

1. Click on the API information in the terminal interface

2. Enter the number of requests you want to buy and click Buy

3. Scan the QR code through MetaMask

4. Confirm the transaction
