How this service works
Native SOL balance (lamports and SOL) for any Solana address. Deterministic, no LLM.
Output
Returns a JSON object containing the chain name ('solana'), the queried address, the balance in lamports (smallest unit), the balance in SOL as a string, and the slot number at which the balance was read. Returns null values for each field if the address is not found or the query fails.
Example use cases
Check wallet funding before airdrop
“Before I send the airdrop, check how much SOL is currently in wallet 7EcDhSYGxXyscszYEp35KHN8vvw3svAuLKTzXwCFLtV1 so I know it's funded.”
Monitor agent treasury balance
“What's the SOL balance right now for my agent's treasury wallet at 4Nd1mBQtrMJVYVfKf2PX98ZlqkF3koZkx6QsXo8TUVSP?”
Verify payment receipt on Solana
“Did the payment arrive yet? Check the SOL balance on wallet BVrqMNgoxnHoJqFVbGPAdCaTbNRdFtbGMkJbFU2hXgMb and tell me how many lamports it holds.”
Technical details
Endpoint
GEThttps://138-197-15-135.sslip.io/v1/solana/balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call SOL balance lookup for any Solana wallet address without setting up your own RPC node or managing API keys. Ideal for AI agents that need occasional onchain balance checks on Solana and want to pay fractionally via x402/USDC on Base rather than maintaining a subscription.
Side effects
- Invalid or malformed base58 address returns an error or null fields
- Address with zero balance may return 0 lamports and '0' SOL
- Network or RPC timeout may cause null slot or null balance fields
- Payment failure via x402 (insufficient USDC) blocks the request before execution
- Rate limiting or node unavailability may result in failed responses
