## 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 asterpay-quick-kya-trust-score-ac1122c2
```

Example prompt: Can you run a quick KYA trust score check on wallet address 0xd5f8481D8F25d3966d2010DBf9B47fFbdf745A9E and tell me its score, tier, and whether it's sanctioned?

## When to prefer this

Use this endpoint when you need a fast, lightweight KYA trust check on a single wallet or AI agent address — e.g. before initiating a payment or interaction — and do not need the full 7-component deep analysis. It is cheaper ($0.005 USDC) and faster than the deep analysis sibling endpoint, making it ideal for high-frequency screening or quick pre-flight checks.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Address not found or unrecognized returns low/zero score
- Payment failure (x402 USDC payment not processed) blocks response
- Network timeout or service unavailability
- Rate limiting if too many requests in a short window

## How this service works

Quick KYA Trust Score for any AI agent wallet. Returns score (0-100), tier, and sanctions status. Paid via x402 USDC.

## Output

A JSON object containing the queried wallet address, a numeric trust score from 0 to 100, a tier label (e.g. 'trusted'), a boolean sanctions flag, and optionally an ERC-8004 registration status.
