Every Address Latest endpoint
Each operation links to its page in the API reference, with its parameters and responses. Paths take the blockchain and the network, so moving to another chain is a change of path.

Can I try Address Latest for free?
Yes, for 14 days. The Blockchain API free trial includes Address Latest and every other feature, with no card. It ends after 14 days or when its credits run out; after that, calls need a subscription, listed on the pricing page.
Does the Address Latest API support Solana?
Yes. Solana is supported by the Address Latest API through a dedicated Solana handler, on both mainnet and devnet. You can retrieve the current balance and latest transaction state for a Solana address in real time.
What can I retrieve with the Address Latest endpoints?
Address Latest returns the current on-chain state for a specific address in real time, including its balance and recent transaction activity. Depending on the blockchain, this includes confirmed and unconfirmed transactions, unspent transaction outputs (UTXOs) for UTXO chains, internal transactions for EVM chains, and the next available nonce for EVM accounts. It is designed for looking up an address's latest state rather than deep historical archives.
Does Address Latest work on testnets as well as mainnets?
Yes. Address Latest works on both mainnets and testnets for the supported chains, so you can develop and test against networks like Ethereum Sepolia, Bitcoin testnet, and Solana devnet before going to production. Kaspa is the exception, offered on mainnet only.
