## 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 misttrack-address-trace-blockchain-aml-risk-api-393893f0
```

Example prompt: Can you check the MistTrack AML risk on this Ethereum address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE and tell me if it's flagged, what labels it has, and what its risk score is?

## When to prefer this

Choose this endpoint when you need on-chain AML risk assessment and entity labeling for a specific blockchain address, particularly for compliance workflows, fraud investigation, or pre-transaction screening. MistTrack is especially strong for EVM chains, Bitcoin, and Tron. Prefer this over generic blockchain explorers when you need structured risk scores and entity classification rather than raw transaction data.

## Known failure modes

- Unsupported coin symbol returns an error or empty result
- Invalid or malformed blockchain address returns a validation error
- Address has no on-chain history and returns no labels
- Rate limiting or payment failure via x402 protocol blocks the request
- Network-specific address format mismatch (e.g. wrong chain for the coin)
