## 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 usdt-banlist-address-label-lookup-454c44c9 -d '<json body>'
```

Example prompt: Can you label the address 0xdAC17F958D2ee523a2206206994597C13D831ec7 and tell me which exchange or protocol it belongs to, its contract type, and category?

## When to prefer this

Use this endpoint when you need fast, lightweight entity labeling for a blockchain address — specifically to identify exchange ownership, protocol association, contract type, or category. Prefer this over the sibling deep AML risk endpoint when you only need metadata and labels rather than a full risk score and fund flow analysis.

## Known failure modes

- Address not found in database — returns empty or null label fields
- Malformed address input — returns validation error
- Network or upstream timeout — returns 5xx error
- Unrecognized address format — returns 400 bad request
- Payment failure via x402 protocol — returns 402 Payment Required

## How this service works

Get address labels and entity information — exchange name, protocol, contract type, category.

## Output

Returns structured entity information for the queried blockchain address, including the exchange name (if applicable), protocol, contract type, and category label — useful for enriching AML workflows or understanding the identity of an on-chain address.
