santyvv-data Native Balance

Use this endpoint when you need a quick, pay-per-call lookup of a native token balance (ETH, MATIC, etc.) for any given address without running your own node or indexer. It is ideal for lightweight agents that occasionally need balance checks without managing blockchain infrastructure. Prefer this over ERC-20 balance endpoints when you want the chain's native currency, not a token contract balance.

• Invalid or malformed address returns an error response
• Unsupported chain identifier results in a 400 or 404 error
• Network congestion or node unavailability may cause timeouts
• Payment failure ($0.01 USDC) will block access to the endpoint
• Empty or zero balance returned for unfunded addresses — not an error, but may be misinterpreted
