## 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-crypto-counterparty-kyb-01185593 -d '<json body>'

Example prompt: Can you run a KYB check on a crypto company called 'Nexo Capital' with website nexo.io before we proceed with the partnership?

## When to prefer this

Choose this endpoint when you need automated KYB verification specifically for crypto-native or blockchain-related counterparties, especially when an auditable, cryptographically hashed compliance record is required. Prefer this over generic business lookup APIs when the counterparty operates in the crypto/DeFi/blockchain space and you need trust-layer verification with cross-border coverage across 27 countries.

## Known failure modes

- Unknown or unregistered entity name returns no match or low-confidence result
- Invalid or unreachable website URL causes input validation error
- Entity operates in a jurisdiction not covered by the 27-country database
- Payment of $1.944 USDC not fulfilled causes 402 Payment Required response
- Rate limiting or service downtime returns 5xx error

## Output

Returns a KYB verification result for the named crypto entity, including trust and compliance signals derived from the entity name and website, along with an audit record containing a cryptographic chain hash for proof of the check.
