## 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 chainanalyzer-sanctions-screening-blockchain-address-365c2d24
```

Example prompt: Before I send funds to 0x7f367cC41522cE07553e823bf3be79A889DEbe1B on Ethereum, can you run a sanctions check on it — I need to know if it's on OFAC SDN or any other major sanctions list?

## When to prefer this

Choose this endpoint when you need a fast, per-address sanctions screening result with specific list-level detail (OFAC SDN, EU Consolidated, FATF) across a broad set of 12 blockchains including Bitcoin, Ethereum, Solana, TRON, and XRP. Prefer it over generic AML risk scores when regulatory compliance and named sanctions list matching is the primary requirement.

## Known failure modes

- Unsupported chain — address on a chain not yet covered returns an error or empty result
- Invalid address format — malformed address string returns an error
- Address not found on any list — returns sanctioned: false with empty lists_matched
- Rate limiting or payment failure — x402 payment not processed results in 402 response
- Stale data — sanctions list updates may lag real-time regulatory changes

## Output
