## When to prefer this

Use this endpoint when you specifically need the native MATIC balance on the Polygon network for an EVM-compatible wallet address. Prefer this over Ethereum or BSC balance endpoints when the user's assets are on Polygon. It is ideal for DeFi agents, portfolio trackers, gas-check automations, and airdrop verification workflows that require Polygon on-chain data.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Address with zero balance may return 0 rather than an error
- Network congestion or RPC issues may cause timeouts
- Non-Polygon (wrong network) address format may cause unexpected results
- Rate limiting or payment failure may block the request
