## 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 strale-web3-counterparty-kyb-99a6547e -d '<json body>'
```

Example prompt: Can you run a KYB and sanctions screen on the Web3 company Uniswap Labs — their domain is uniswap.org — before we sign a partnership agreement with them?

## When to prefer this

Use this endpoint when you need to perform compliance-grade KYB and sanctions screening specifically on Web3-native entities such as DAOs, DeFi protocols, or crypto projects. It is purpose-built for Web3 counterparties and returns cryptographically auditable records suitable for regulatory documentation. Prefer this over generic KYB tools when your counterparty is blockchain-native and traditional company registries may not have coverage.

## Known failure modes

- Domain not found or unreachable — entity cannot be matched to a known organization
- Entity name ambiguous — multiple matches found, requiring disambiguation
- Entity is on a sanctions list — result flags the match with relevant list details
- Input validation failure — malformed domain or missing required fields
- Timeout — external data sources for KYB unavailable
- Insufficient data — entity too new or obscure to verify conclusively
