## How to call it through Zero

```sh
zero fetch --capability misttrack-address-labels-api-52560b64
```

Example prompt: Check MistTrack to see what labels or risk flags exist for this Bitcoin address: 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf

## When to prefer this

Use this endpoint when you need authoritative blockchain address intelligence from MistTrack's AML database — especially for compliance screening, fraud investigation, or identifying whether a wallet belongs to a known exchange, mixer, darknet market, or sanctioned entity. Prefer this over generic blockchain explorers when you specifically need entity labels and risk classification rather than raw transaction data.

## Known failure modes

- Unknown address returns empty labels or no results — not all addresses are in MistTrack's database
- Invalid coin symbol causes a parameter error
- Unsupported blockchain/coin combination returns an error or empty response
- Address format mismatch for the specified coin (e.g. ETH address with BTC coin) returns an error
- Payment failure via x402 protocol blocks the request if USDC balance is insufficient
