How this service works
The native SOL balance and basic account state for any Solana address, read from the public ledger: lamports and SOL, whether the account exists, its owning program, executable flag, and data size. Pass a base58 address in the path. Keyless on-chain data — no Jupiter API, no account. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.
Output
Returns the native SOL and lamport balance, a boolean indicating whether the account exists, the owning program public key, whether the account is executable, and the size of the account's data — all sourced directly from the Solana public ledger without requiring an API key.
Example use cases
Check wallet SOL balance
“How much SOL does the address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM have right now? I need the lamport amount too.”
Verify Solana account existence
“Can you check if the Solana account at address ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJe8bXR actually exists on-chain and who owns it?”
Audit executable program account
“I need to know whether the Solana address BPFLoaderUpgradeab1e11111111111111111111111 is marked as executable and what size its on-chain data is.”

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/solana/balance/:addressWhen to prefer
Choose this endpoint when you need raw, on-chain native SOL balance and account metadata for a Solana address without managing API keys or subscriptions. It is ideal for lightweight wallet-monitoring tasks, verifying account existence, or auditing program ownership on Solana. Prefer it over third-party portfolio aggregators when you want direct ledger data with pay-per-call pricing and no account setup.
Side effects
- Invalid base58 address format — returns error indicating malformed address
- Account does not exist on-chain — returns exists: false with zero balance
- Network or RPC availability issues — may return a timeout or upstream error
- Incorrect path parameter (missing address) — returns 404 or bad request
