FAQPage Schema
How do I authenticate Aster Futures API requests for trading?▼

To authenticate Aster Futures API requests, you must generate signed calls using your user address, API signer, nonce, timestamp, and signature. This EIP-712 based workflow ensures request integrity for accessing trading endpoints securely.

What is EIP-712 signed access for the Aster Futures API?▼

EIP-712 signed access for the Aster Futures API is a secure authentication mechanism that enforces nonce and timestamp validation. It eliminates private key exposure by requiring a signature generated from your wallet address and API secret.

How do I place orders and query balances using the Aster Futures API?▼

You can place orders and query balances by invoking signed USER_DATA endpoints through the Aster API workflow. These authenticated calls require your user address, API signer, nonce, and signature to execute successfully.

Can I transfer funds between futures and spot accounts using signed API calls?▼

Yes, you can transfer funds between futures and spot accounts by sending authenticated, signed requests to the Aster API. This requires generating a valid signature with your API signer and nonce to authorize the transfer.

Do I need to expose my private key to access Aster market data endpoints?▼

No, you do not need to expose your private key to access Aster market data endpoints. The API distinguishes between public endpoints and signed USER_DATA endpoints, using nonce-based EIP-712 signing to reduce fraud risk.
