## 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 agent-commerce-radar-seller-benchmark-9ccd328f -d '<json body>'
```

Example prompt: Can you check where my wallet 0xAbC123... ranks on the x402 seller leaderboard — I want to know my percentile, total USD volume, and how many calls I've settled?

## When to prefer this

Use this endpoint when you need to benchmark a specific x402 API seller by wallet address or origin domain against the public settled-activity leaderboard. Prefer this over generic analytics tools when the query is specifically about x402 micropayment settlement rank, call volume, or competitive percentile positioning in the agent commerce ecosystem.

## Known failure modes

- Wallet or origin not found on leaderboard — 'found: false' returned with null/zero metrics
- Invalid wallet address format causes request rejection
- Leaderboard data may lag real-time settlements by some polling interval
- Missing both 'origin' and 'wallet' fields may return an error or empty result
- Low-volume sellers may have rank and percentile but minimal volume data

## How this service works

Current paid market intelligence for x402 buyers and sellers, grounded in public settled-activity leaderboards.

## Output

Returns a JSON object with: rank (integer position on leaderboard), found (boolean indicating if the seller was located), volumeUsd (total settled USD volume), percentile (seller's percentile ranking among all x402 sellers), and callsSettled (total number of settled API calls).
