How this service works
SOL balance of any Solana address (lamports + SOL string, confirmed, cached <=2 s).
Output
Returns a JSON object containing the queried Solana address, its balance in lamports (integer), and its balance as a SOL string (e.g. '1.5'). Data is confirmed on-chain and served from a cache no older than 2 seconds.
Example use cases
Pre-transaction balance check
“Before I send this transaction, can you check how much SOL is currently in the wallet HN7cABqLq46Es1jh92dQQisAq662SmxELLLsHHe4YWrH so I know if there's enough to cover it?”
Portfolio balance monitoring
“I need to keep an eye on the SOL balance for address 4Nd1mBQtrMJVYVfKf2PX98HegFpyhGmxbzFEGEnHDpGd — can you fetch the current balance in both SOL and lamports?”
Airdrop eligibility verification
“Can you check the SOL balance of wallet 3FZbgi29cpjq2GjdwV8eyHuJJnkLtktZc5fRRFpfGBZj to see if it's a fresh address with zero balance before we send the airdrop?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/sol/balance/:addr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost, confirmed SOL balance for any Solana address without managing your own RPC node or API keys. The 2-second cache makes it ideal for near-real-time balance checks in agent workflows, pre-transaction validation, and portfolio monitoring. Prefer it over raw RPC calls when you want a simple HTTP GET with no authentication overhead and a clean JSON response.
Side effects
- Invalid or malformed base58 address returns an error response
- Address not found on-chain (never funded) may return 0 lamports or an error
- RPC node unavailability may cause a timeout or 5xx error
- Cache staleness up to 2 seconds may reflect slightly outdated balance in high-frequency scenarios
