## When to prefer this

Choose this endpoint when you need a no-signup, no-API-key way to fetch a Solana wallet's SOL balance on a pay-per-use basis. Ideal for AI agents that need occasional balance lookups without maintaining API credentials, especially when already operating within the x402 USDC micropayment ecosystem on Base.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error response
- Insufficient USDC balance for x402 micropayment results in payment failure and no data returned
- Network issues with Solana RPC may cause timeouts or stale data
- Missing or malformed schema parameter may result in a bad request error
