## How to call it through Zero

```sh
zero fetch --capability canaryguard-wallet-drainer-check-cd7d9821
```

Example prompt: Before I send funds, can you check if wallet address 0xAbC123...def on Base has any Permit2 drainer exposure, approval phishing history, or OFAC sanctions flags?

## When to prefer this

Choose this endpoint when you need a fast, multi-signal risk check on an EVM wallet specifically on Base, combining Permit2 drainer exposure, phishing approval history, and OFAC sanctions into a single call. Prefer this over generic blockchain explorers when you need structured risk verdicts rather than raw transaction data, especially for pre-trade counterparty screening or DeFi safety workflows.

## Known failure modes

- Invalid or malformed wallet address (non-0x format) returns validation error
- Unsupported chain_id other than Base (8453) may return unsupported chain error
- Address with no on-chain history may return empty risk signals but not an error
- Network timeout or Render cold-start delay may cause slow initial response
- Payment failure (insufficient USDC balance) blocks request with 402 status
