Update: API rate limit will be reduced to 15 requests per minute, 1 request per second for the 3 apis from July 28th.

Dear community,

Binance DEX will conduct an upgrade to optimize API to provide a better service for our users. Here are the specific changes:

Binance DEX will introduce these new Rest API endpoints, estimated to be in force on 2021-06-21 03:00 AM (UTC):

  • Get a batch of blocks - https://api.binance.org/bc/api/v1/blocks?startHeight={startHeight}&endHeight={endHeight}
  • Get a block for a particular height -  https://api.binance.org/bc/api/v1/blocks/{blockHeight}
  • Get transactions in a particular block height -  https://api.binance.org/bc/api/v1/blocks/{blockHeight}/txs
  • Search transactions by criteria -  https://api.binance.org/bc/api/v1/txs?address={address}&startTime={startTime}&endTime={endTime}
  • Get a transaction by a hash - https://api.binance.org/bc/api/v1/txs/{txHash}

These new endpoints will provide better service than the following RPC endpoints, which will be retired in 5 days. Before the deadline,  the rate limits of these old endpoints will be decreased by ~30% every 15 days compared to the current values.

Developers should switch to these new API as soon as possible. Please refer to the migration guide for more details.

If you are using Binance Chain java-sdk, please bump version to v1.1.2 asap https://github.com/binance-chain/java-sdk/releases/tag/v1.1.2

For further details and updates, please refer to our full API doc.

Please take necessary precautions and update your application accordingly.

Thanks for your support!
