params[1]object

Configuration object:

  • encoding (string) - json, jsonParsed, base58, base64
  • commitment (string) - finalized or confirmed
  • maxSupportedTransactionVersion (integer)
curl https://rpc.nln.clr3.org \  -H "Content-Type: application/json" \  -H "x-api-key: YOUR_API_KEY" \  -d '{"jsonrpc":"2.0","id":1,"method":"getTransaction","params":["2nBhEBYYvfaAe16UMNqRHre4YNSskvuYgx3M6E4JP1oeYYd8Tm5ATGQ7ufRYM5jnFdoP8bHKevSX1Tc3FRxPpM",{"encoding":"jsonParsed","maxSupportedTransactionVersion":0}]}'

getTransactionCount

POST - JSON-RPC

Returns the current transaction count from the ledger.

params[0]object

Configuration object with optional commitment and minContextSlot.

curl https://rpc.nln.clr3.org \  -H "Content-Type: application/json" \  -H "x-api-key: YOUR_API_KEY" \  -d '{"jsonrpc":"2.0","id":1,"method":"getTransactionCount"}'

getSignatureStatuses

POST - JSON-RPC

Returns the statuses of a list of transaction signatures (max 256).
