## 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-top-buyers-6cc505c9
```

Example prompt: Show me the top 20 on-chain AI agent buyers ranked by activity, including their ERC-8004 trust scores and any sybil risk flags from SweetAI.

## When to prefer this

Choose this endpoint when you need a leaderboard or ranked list of the most active on-chain AI agent buyers with trust and sybil risk context, rather than looking up a single wallet or agent. It is the right choice for market research, fraud monitoring, or identifying high-value participants across the whole buyer population.

## Known failure modes

- limit parameter out of range (must be 1-100) returns validation error
- payment not processed or expired x402 token returns 402
- no buyers found for the current time window returns empty list
- upstream on-chain data unavailable returns 503
