Pathfinder currently supports querying the Starknet network for state. For the full list of available queries, see Pathfinder API.

​
JSON-RPC API

Use curl or Postman. 
curl -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":"0","method":"METHOD","params":[PARAMS]}' YOUR_CHAINSTACK_ENDPOINT
where
  • METHOD — a supported JSON-RPC API method
  • PARAMS — request parameters if any
  • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password

​
Starknet.js

  1. Install Starknet.js. See Starknet.js guide.
  2. Use RpcProvider to connect to your Starknet node and get the latest block: 
    import { RpcProvider } from 'starknet';
const provider = new RpcProvider({
  nodeUrl: 'YOUR_CHAINSTACK_ENDPOINT',
})
provider.getBlockNumber().then(console.log);
    where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password. See also node access details.

​
Starknet.py

  1. Install Starknet.py. See Starknet.py guide.
  2. Use FullNodeClient to connect to your Starknet node and retrieve a transaction by hash: 
    from starknet_py.net.full_node_client import FullNodeClient
from starknet_py.net.networks import MAINNET

node_url = "YOUR_CHAINSTACK_ENDPOINT"
full_node_client = FullNodeClient(node_url=node_url, net=MAINNET)
call_result = full_node_client.get_transaction_sync(tx_hash="0x50c1941ab13ccc5d9785ceda1d0d7a47be01865eecb795a62f4e589ddca0258")
print(call_result)
    where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password. See also node access details.

​
Starkli

Rust-based CLI tool to interact with the Starknet blockchain.
  1. Install Starkli. See Starkli Book.
  2. In a terminal run commands with the --rpc flag: 
    starkli block-number --rpc YOUR_CHAINSTACK_ENDPOINT
    where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password. See also node access details.
Find more JSON-RPC methods on the Starkli documentation.
