## How to call it through Zero

```sh
zero fetch --capability misttrack-address-action-api-f82c1b07
```

Example prompt: Can you check if this Ethereum address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE has any AML risk flags or known labels on MistTrack?

## When to prefer this

Choose this endpoint when you need on-demand, per-address AML risk classification and entity labeling for a specific blockchain address across supported coins. It is ideal for compliance workflows, pre-transaction screening, fraud detection, or due diligence where you need MistTrack's proprietary risk intelligence database. Prefer this over generic blockchain explorers when you specifically need AML labels, risk scores, and illicit activity flags 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 with no transaction history may return no labels
- Rate limiting or payment failure via x402 protocol returns 402 Payment Required
- Address on a chain not yet indexed by MistTrack returns no data
