## How to call it through Zero

```sh
zero fetch --capability xynaptic-wallet-screen-ca6eb6e1
```

Example prompt: Before I send 0.5 ETH to 0x4e83362442B8d1beC281931Ce3E5Bd69aE4B420F, can you run a wallet screen on that Ethereum address and tell me the overall risk level and any risk signals?

## When to prefer this

Choose this endpoint when you need a quick, structured pre-transaction risk assessment for a specific Bitcoin or Ethereum wallet address — especially when you want actionable risk signals (drained, contract, low activity, high exposure) with severity levels rather than raw on-chain data. It is ideal for agent workflows that gate a payment or transfer on a risk check. It is not a substitute for formal AML/KYC compliance tooling.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain value (anything other than btc or eth) returns a validation error
- Network timeouts if the underlying blockchain RPC is slow
- Address with no on-chain history may return minimal data but should not error
- Missing required address or chain query parameter returns a 400 bad request

## How this service works

Xynaptic Wallet Screen — pre-transaction risk screening of any Bitcoin or EVM address: on-chain profile (balance, tx count) plus risk signals (empty/drained wallet, contract address, low activity, high exposure) each with a severity, and an overall risk level. Informational screening, not a compliance decision. GET ?address=...&chain=btc|eth.

## Output

Returns an on-chain profile for the address (balance, transaction count) and a list of risk signals (e.g. empty wallet, drained wallet, contract address, low activity, high exposure), each with a severity level, plus an aggregated overall risk level. This is informational screening only, not a regulatory compliance decision.
