## 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 api-x402-printmoneylab-com-89b25906
```

Example prompt: Pull the top 50 buyers for service ID 'svc_abc123' and show me their wash-trading labels, confidence scores, and the full signal breakdown for each wallet.

## When to prefer this

Use this endpoint when you need deep per-buyer wash-trading intelligence for a specific service — including signal-level explanations and confidence scores — rather than just aggregate volume stats or a simple wallet lookup. Prefer over the single-wallet endpoint when you want to survey all top buyers at once.

## Known failure modes

- Invalid or unknown service_id returns 404 or empty result
- Service has fewer than 50 buyers — returns however many exist
- Payment not attached or insufficient USDC triggers 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Malformed request returns 400 with validation error

## How this service works

Top 50 buyers per service with full label classification, confidence scores, and signal-by-signal breakdown.

## Output

A ranked list of up to 50 buyer wallets for the specified service, each annotated with an 8-label wash-trading classification, a confidence score, and a detailed breakdown of the individual signals that drove the classification.
