Wallet balances and transaction lookups for Solana and Base

SOL and token holdings with USD values on Solana, ETH and major tokens on Base, and decoded transaction receipts on both.

On Solana, the wallet endpoint lists SOL and all token holdings of an address with symbols, prices and values, largest first. The transaction endpoint shows whether a signature succeeded, the fee, the programs used and the SOL and token changes per account.

On Base, the wallet endpoint returns ETH and the balances of major tokens plus any contracts you list, and the transaction endpoint decodes status, fee and ERC-20 transfers. Everything is read live from the chain.

The calls

Each call returns 402 with the price until a payment is attached; an x402 client pays and retries automatically. Calls that fail are not charged. See Get started and the guide for bots and agents for code.

solana-wallet-balances $0.01 per call

SOL balance and token holdings of any Solana address, with symbols, USD prices and values, largest first.
