Get Balance

Use the Binance Link wallet user-assets API to query a user's available crypto balance before an institutional sell flow.

When to use​

Use this before the Sell flow to show the user's available crypto balance and validate that the user has enough crypto before requesting or executing a sell quote.

API reference​

For balance lookup, refer to the Binance Link wallet user-assets API agreed for your institutional integration.

  1. Complete user onboarding and obtain the required userId.
  2. Query the user's available crypto balance through Binance Link wallet user-assets.
  3. Use Get Crypto List for Sell and Get Trading Pair to confirm the selected asset and target fiat currency are supported.
  4. Use Get Fiat/Crypto Amount Limit to validate the selected amount.
  5. Use Get Quote and Execute Quote to continue the sell flow.

Implementation note​

Use the balance response only as a pre-check. The final order execution result should still be handled through Execute Quote, Get Single Transaction, transaction list query, and webhooks.
