## 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-quick-82849836 -d '<json body>'
```

Example prompt: Before you send the USDC payout, run a quick risk screen on 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD on Base and tell me if it's safe, caution, or danger.

## When to prefer this

Choose the quick tier when you need low-latency, pre-transfer screening and speed is more important than depth — ideal for real-time agent workflows where a fast safe/caution/danger signal is sufficient and cost efficiency matters ($0.02 per call). Prefer the standard or deep tiers when a more thorough on-chain behavioral analysis is required.

## Known failure modes

- Invalid address format (not a valid 0x EVM address) returns a validation error
- Unsupported chain (non-Base) returns an error since only Base is currently supported
- Network timeout or upstream sanctions database unavailability may return a service error
- Rate limiting or payment failure via x402 protocol returns a 402 or 429 error

## How this service works

Verdix quick ($0.02): call before an agent pays or sends funds to an EVM address on Base, e.g. an x402 payTo, a withdrawal or a pasted address. Checks OFAC sanctions, scam/phishing lists, live address poisoning, contract/deployer signals and address age. Returns safe/caution/danger with reasons: stop on danger, confirm on caution.

## Output

Returns a verdict of 'safe', 'caution', or 'danger' based on OFAC sanctions list matching, known scam and blacklist database hits, and a fast on-chain address-age heuristic. 'Safe' means no risk signals were detected but does not guarantee the address is legitimate.
