Solana

Read the Solana blockchain through its keyless public JSON-RPC endpoints: SOL and SPL token balances, account state, a wallet's recent transactions, a transaction's full detail with the balance changes it caused, token supply, and cluster health. No account or API key required.

Actions

Action	What it does
Get account info	Get an account's state: the program that owns it, its balance, whether it is executable, and its data.
Get network status	Check that a Solana cluster is healthy and see where it is in the current epoch: the slot it has reached, how far through the epoch that is, and the version the node runs.
Get recent transactions	List the transactions that touched an address, newest first, with each one's signature, time, and whether it succeeded.
Get SOL balance	Get the SOL balance of any wallet or account address, in lamports and in SOL.
Get token balances	List the SPL token balances held by a wallet, one row per token account with its mint and amount.
Get token supply	Get the circulating supply of an SPL token from its mint address, as the raw amount and with the mint's decimals applied.
Get transaction	Get a confirmed transaction by signature, with what it actually moved worked out: the fee, the instructions it ran, and the SOL and token balance changes per account.

Get account info

Get an account's state: the program that owns it, its balance, whether it is executable, and its data. Accounts the node can decode (token accounts, mints, stake and vote accounts) come back as readable fields; anything else keeps its data as base64.

Inputs

AddressaddresstextRequired: Base58 address of the account to read. Any account works: a wallet, a token account, a mint, or a program.
Clusterclustertext: Which Solana cluster to read from. Mainnet Beta is the live chain carrying real value; Devnet and Testnet are for trying a workflow out first and their tokens are worth nothing. Defaults to Mainnet Beta.One of: mainnet-beta (Mainnet Beta (live)), devnet, testnet. Default: mainnet-beta.
Commitmentcommitmenttext: How settled the data has to be before the node answers. 'Finalized' is a block that can no longer be rolled back and is the right choice for anything about money; 'confirmed' is a couple of seconds fresher; 'processed' is the newest and the least certain. Defaults to finalized.One of: finalized (Finalized (safest)), confirmed, processed (Processed (newest)). Default: finalized.

Outputs

account_typetext: Kind of account, e.g. 'mint' or 'account'
addresstext: Address the account is for
clustertext: Cluster it was read from
context_slotnumber: Slot the node answered at, i.e. how current this reading is
data_base64text: Raw account data, when it could not be decoded
executabletrue/false: Whether the account is a program itself
existstrue/false: False when nothing has ever been created at this address; the rest of the fields are then empty
lamportsnumber: Balance in lamports, the chain's own unit (1 SOL = 1,000,000,000)
ownertext: Address of the program that owns the account
owner_programtext: Name of that program when it is a well-known one, e.g. 'SPL Token Program'
parsedobject: Decoded account fields, when the node could
programtext: Program the data was decoded as, e.g. 'spl-token'
rent_epochnumber: Epoch rent is next owed, when one applies
rent_exempttrue/false: Whether the account holds enough to owe no rent
solnumber: The same balance expressed in SOL
sol_stringtext: The same balance in SOL as an exact decimal string, for balances too large to hold in a number without rounding
spacenumber: Size of the account's data, in bytes

}

Get recent transactions

List the transactions that touched an address, newest first, with each one's signature, time, and whether it succeeded. This is how a workflow watches a wallet: hand a signature to 'Get transaction' for the detail, or stop at the last one already seen so a scheduled run only picks up what is new.

Until signatureuntiltext: Stop at this signature and return only what is newer than it. Pass the 'newest_signature' a previous run saw so a scheduled workflow picks up only new activity.
Clusterclustertext: Which Solana cluster to read from. Mainnet Beta is the live chain carrying real value; Devnet and Testnet are for trying a workflow out first and their tokens are worth nothing. Defaults to Mainnet Beta.One of: mainnet-beta (Mainnet Beta (live)), devnet, testnet. Default: mainnet-beta.
Commitmentcommitmenttext: How settled the data has to be before the node answers.
