## 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 payperscreen-crypto-address-screening-31b80d56
```

Example prompt: Can you screen the wallet address 0x4e9ce36e442e55ecd9025b9a6e0d88485d628a67 for OFAC sanctions, stablecoin freezes, and any links to known hacks before I send funds to it?

## When to prefer this

Choose this endpoint when you need real-time, per-call crypto address compliance screening covering OFAC sanctions, stablecoin freeze lists, and hack-associated wallets — especially in payment or DeFi contexts where you need to verify a counterparty before transacting. It is priced per-call at $0.02 USDC via x402, making it suitable for on-demand screening rather than bulk batch jobs. Prefer this over general blockchain analytics tools when you specifically need sanctions and freeze-list coverage in a single lightweight API call.

## Known failure modes

- Missing or malformed wallet address returns a 400 error
- Unsupported chain format may return no results or an error
- Payment failure (x402) if USDC balance is insufficient
- Address not found on any monitored list returns a clean/clear result which should not be confused with a guaranteed safe status
- Network timeouts may occur if screening databases are slow to respond

## How this service works

Check names, crypto wallets, emails and IP addresses against official sanctions lists and risk signals. 2 cents a check, no contract, no account. Built so your software, or your AI agent, can run it on every customer and every payment.

## Output

Returns a risk assessment for the queried wallet address, including whether it matches OFAC sanctions lists, is subject to stablecoin issuer freeze orders (e.g. USDC/USDT blacklists), or is associated with known hack or exploit proceeds. Likely includes a risk flag, match details, and relevant list identifiers.
