## 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 sweetai-x402-seller-verdict-938cf433
```

Example prompt: Before I pay that unknown x402 endpoint I found, can you check SweetAI's seller verdict to see if it's REAL or a FARM — and tell me the repeat-usage ratio and 11-day demand trend?

## When to prefer this

Use this endpoint when you encounter an unfamiliar x402 seller and need a quick, data-backed trust signal before committing a micropayment. It is especially valuable in automated agent pipelines that dynamically discover and call x402 APIs, where manual vetting is impractical. Prefer this over generic uptime checks or manual inspection when you need a fraud/farm detection verdict with demand-trend context specific to the x402 payment ecosystem.

## Known failure modes

- Unknown or uncrawled seller endpoint — verdict may return DEAD or null if not yet in the SweetAI catalog
- Stale data if the daily sweep has not yet processed recent activity
- Rate limiting or payment failure if the $0.02 USDC x402 payment is not processed correctly
- Invalid HTTP method passed — schema only allows GET, HEAD, DELETE

## How this service works

Call this before paying an x402 endpoint: Binary verdict (REAL/EMERGING/FARM/DEAD) with repeat-usage ratio and demand trend from daily catalog sweep

## Output

Returns a trust classification (REAL, EMERGING, FARM, or DEAD) for the queried x402 seller endpoint, accompanied by the number of unique payers, total call volume, repeat-usage ratio, and a rolling 11-day demand trend derived from daily sweeps of the x402 catalog.
