Example prompt: Pull the full token transfer history on Polygon for wallet address 0x742d35Cc6634C0532925a3b8D4C9B7e6F1d2e3A4 so I can see every token that's been sent to or from it.

## When to prefer this

Choose this endpoint when you specifically need token transfer history on the Polygon network for a given EVM address. It is ideal for auditing wallet activity, tracing token flows, or building transaction reports on Polygon. Prefer sibling endpoints for Base, Ethereum, or BSC networks. Use this over generic blockchain explorers when you need programmatic, agent-callable on-chain data at low cost.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Address with no transfer history returns an empty result set
- Polygon node connectivity issues may cause timeouts
- Rate limiting or payment failure (x402) blocks the request
- Network congestion may cause delayed responses
