## 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 onyx-aml-blockchain-address-screener-acf64e95 -d '<json body>'
```

Example prompt: Can you screen this TRON wallet address TXyz1234abc for AML risk and check if it's on the Tether USDT blacklist or flagged on any major exchange?

## When to prefer this

Use this endpoint when you need a quick, on-demand AML and blacklist screening for a single blockchain address across TRON, EVM-compatible chains, or Solana — particularly when dealing with USDT/Tether blacklist checks or investigating frozen funds on Binance, Bybit, or OKX. Prefer this over generic blockchain explorers when you need compliance-specific risk signals rather than raw transaction data.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on supported chains may return inconclusive result
- Rate limiting or payment failure returns 402 or 429
- Temporary upstream data source unavailability may delay results
