How this service works
Use before sending SOL or paying fees, to confirm the wallet really holds enough. Never rely on a balance remembered from earlier in a conversation. Reads a wallet's native SOL balance directly from the chain.
Output
Returns the wallet's current native SOL balance as read directly from the Solana blockchain, typically expressed in SOL and/or lamports. The value reflects the true on-chain state at the moment of the call, not a cached or estimated figure.
Example use cases
Pre-transfer SOL sufficiency check
“I want to send 1.5 SOL to my friend — before you build the transaction, check the live SOL balance on wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM to make sure I actually have enough plus a little extra for fees.”
Agent fee-reserve verification
“My trading bot is about to execute a swap — first verify the current on-chain SOL balance for wallet 3h1zGmCwsRJnVk5BuRNMLsPaQu1y2kcQxD3z5LfD1Q9n to confirm it has at least 0.01 SOL left to cover transaction fees.”
User balance inquiry before DeFi action
“Before I stake anything, can you pull the real-time SOL balance straight from the chain for my wallet address 5FHwkrdxkzXEV5mWzSfBFpVxeGmf82oJXy3WTWnVBJVR? I don't trust the number from earlier in our chat.”
Technical details
Endpoint
POSThttps://solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/get_solana_balance?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an agent needs a real-time, authoritative SOL balance before executing or signing any transaction — especially when fees or transfer amounts depend on confirmed available funds. Prefer this over any cached or in-memory balance value, as blockchain state can change between turns in a conversation. It is specifically designed for pre-transaction validation on Solana, not for token (SPL) balances.
Side effects
- Invalid or malformed wallet address returns an error indicating the address could not be parsed
- Network or RPC errors from the Solana cluster may cause timeouts or unavailable responses
- Wallet address with no history (unfunded) may return zero balance or account-not-found
- Rate limiting may occur under high request volume
