index.getLastAccepted RPC Method

Like all of the Index API methods, the index.getLastAccepted method is available across the Avalanche C-Chain, X-Chain, and P-Chain. Refer to the following list of endpoints for each chain that this method can be used on.

Endpoints:

X-Chain Transactions: /ext/index/X/tx
X-Chain Vertices: /ext/index/X/vtx
P-Chain Blocks: /ext/index/P/block
C-Chain Blocks: /ext/index/C/block

For more information, see the Index API homepage.

The API credit value for this method is 1 . To learn more about API credits and each method's value, visit the API Credits page.

Parameters:

encoding - String - (optional) Encoding value can only be "hex".

Returns:

id - string - The container's ID.
bytes - string - The byte representation of the container.
timestamp - string - The time at which the node accepted the container.
encoding - string - Encoding is "hex" only.
index - string - How many containers were accepted in this index before this one.

Code Examples:

The following examples are calling the index.getLastAccepted method on the X-Chain Transactions endpoint: /ext/index/X/tx. To call this method on Avalanche’s other endpoints, replace the /ext/index/X/tx with any of the above listed endpoints in your code.

web3py
ethers
curl

from web3 import Web3, HTTPProvider
w3 = Web3(HTTPProvider('http://sample-endpoint-name.network.quiknode.pro/token-goes-here/ext/index/X/tx'))
params = {
    "encoding":"hex"
}
request = w3.provider.make_request('index.getLastAccepted', [params])
print(request)

const ethers = require("ethers");

(async () => {
  const provider = new ethers.providers.JsonRpcProvider(
    "http://sample-endpoint-name.network.quiknode.pro/token-goes-here/ext/index/X/tx"
  );
  const params = {
    "encoding": "hex",
  };
  const result = await provider.send("index.getLastAccepted", params);
  console.log(result);
})();

curl --location --request POST http://sample-endpoint-name.network.quiknode.pro/token-goes-here/ext/index/X/tx \
--data-raw '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"index.getLastAccepted",
    "params": {
        "encoding":"hex"
    }
}'
