## 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 x402-data-api-sellers-grouped-by-origin-5f004ff5
```

Example prompt: Show me the top 20 x402 sellers ranked by number of distinct payers, including how many APIs each origin lists and their 30-day call volume.

## When to prefer this

Use this endpoint when you need a market-level view of x402 sellers aggregated by domain — ideal for competitive analysis, identifying top publishers, or understanding the distribution of API offerings across the x402 ecosystem. Prefer this over per-seller or per-API endpoints when the goal is a ranked overview of all origins rather than details on a specific seller.

## Known failure modes

- Invalid sort enum value returns validation error
- Limit out of range (>50 or <1) returns validation error
- Payment not attached or insufficient USDC returns 402
- No data available for the requested period returns empty results

## How this service works

x402 sellers grouped by origin (domain): how many APIs each lists, its best API's payers, its calls in 30 days and its median price.

## Output

A ranked list of x402 seller origins (domains), each with: number of APIs listed, best API's payer count, total 30-day call volume, and median API price. Supports sorting by APIs count, payers, or calls, and a configurable result limit.
