Example use cases

Portfolio balance monitoring

Technical details
Endpoint
POSThttps://basebrain-ai.vercel.app/api/rapid/solana-balanceWhen to prefer
Use this endpoint when you need a quick, on-demand lookup of the SOL balance for a specific Solana wallet address. It is suitable for confirming funding before executing transactions, monitoring wallet activity, or displaying balances in an agent workflow. Prefer this over building a direct RPC call when you want a simple pay-per-use API without managing Solana node infrastructure.
Side effects
- Invalid or malformed Solana public key returns an error
- Network or RPC node unavailability may cause timeouts
- Empty or non-existent wallet returns zero balance or error
- Rate limiting may occur under high request volume
- Missing required wallet address parameter results in bad request error
