Binance Chain DEX API Upgrade Announcement 08/25

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.

• https://docs.binance.org/api-reference/dex-api/paths.html#apiv2transactions-in-blockblockheight
  

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

Please take necessary precautions and update your application accordingly.
