## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability verdix-address-risk-deep-c5501518 -d '<json body>'
```

Example prompt: Before I send funds to 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE on Base, run a deep Verdix risk screen on that address — I want the full OFAC, blacklist, and on-chain behaviour analysis before anything moves.

## When to prefer this

Choose the deep tier when you need the most comprehensive risk assessment available — particularly for high-value transfers, onboarding new counterparties, compliance-sensitive payouts, or when a quick/standard tier returned a 'caution' result and you need deeper investigation. The deep tier adds full on-chain behaviour analysis and activity pattern review on top of the OFAC and blacklist checks offered by lighter tiers, making it the right choice when the cost of a bad transfer far exceeds the $0.50 screening fee.

## Known failure modes

- Invalid address format (not matching 0x[40 hex chars] pattern) returns a validation error
- Unsupported chain value (anything other than 'base') returns an error
- Network timeout or upstream data provider outage may return 5xx errors
- Address with insufficient on-chain history may yield a limited behaviour analysis
- Payment failure (insufficient USDC) blocks the request before analysis begins

## How this service works

Verdix deep ($0.50): call before large or first-time payments to an EVM address on Base when your policy asks for the top tier. Same full check set as standard: sanctions, scam/phishing lists, address poisoning, contract/deployer signals, on-chain behaviour. Returns safe/caution/danger with reasons.

## Output

Returns a verdict of 'safe', 'caution', or 'danger' for the screened address, backed by OFAC sanctions database checks, known scam and blacklist database lookups, and deep on-chain behaviour analysis including transfer history and activity patterns. A 'safe' verdict means no risk signals were detected but is not an absolute guarantee.
