platform.getHeight - AVAX

Example code for the platform.getHeight JSON-RPC method. Complete guide on how to use platform.getHeight JSON-RPC in GetBlock Web3 documentation.

Returns the current P-Chain block height. P-Chain produces blocks via Snowman consensus and finalizes within sub-second timeframes.

Parameters

None

Request Example

curl --location --request POST 'https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/P' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "platform.getHeight",
    "params": {},
    "id": "getblock.io"
}'

import requests
import json

url = "https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/P"

payload = json.dumps({
    "jsonrpc": "2.0",
    "method": "platform.getHeight",
    "params": {},
    "id": "getblock.io"
})

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, data=payload)
print(response.text)

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {

    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/ext/bc/P")
        .header("Content-Type", "application/json")
        .json(&payload)
        .send()
        .await?;

    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);

    Ok(())
