Node API - BNB


API AuthenticationClick to view API Authentication details
API calls require authentication with API key via Authorization request header or URL property. Calls are made to one of the Bnb Node API endpoints found in your app's dashboard.

For example: https://bsc--mainnet--rpc-archive.datahub.figment.io

Here's some boilerplate to get you started. 
fetch("https://bsc--mainnet--rpc-archive.datahub.figment.io", {
    method: 'POST', // can also be 'GET', 'PUT' or any appropriate method
    headers: {
        "Authorization" : "<api_key>",
        "Content-Type": "application/json" // if method is 'POST'
    },
    body: JSON.stringify({
      // JSON Payload
    })
})

Request Body (try it)
Example Response

  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x"
}
SpecificationView Specification

Parameters

  1. Object - The transaction call object
  • from: DATA, 20 Bytes - (optional) The address the transaction is sent from.
  • to: DATA, 20 Bytes - The address the transaction is directed to.
  • gas: QUANTITY - (optional) Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
  • gasPrice: QUANTITY - (optional) Integer of the gasPrice used for each paid gas
  • value: QUANTITY - (optional) Integer of the value sent with this transaction
  • data: DATA - (optional) Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation

Response

DATA - the return value of executed contract.

eth_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

Request Body (try it)
Example Response
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x5208"
}
SpecificationView Specification

Parameters

See eth_call parameters, expect that all properties are optional. If no gas limit is specified geth uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to executed the call/transaction when the amount of gas is higher than the pending block gas limit.

Response

Parameters

BLOCKCOUNT - Number of blocks in the requested range. 1 ~ 1024 blocks can be requested in a single query. Less than requested may be returned if not all blocks are available. NEWESTBLOCK - Highest number of blocks in the requested range. REWARDPERCENTILES - (optional) Percentage values between 0 and 100, sampled in ascending order.

Response

OLDESTBLOCK - Smallest number block of the returned range. BASEFEEPERGAS - An array of block base fees per gas.

  • [null, B] "anything in first position AND B in second position (and anything after)"
  • [A, B] "A in first position AND B in second position (and anything after)"
  • [[A, B], [A, B]] "(A OR B) in first position AND (A OR B) in second position (and anything after)"
