## 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 agentcheck-x402-bazaar-seller-csv-f6229000
```

Example prompt: Pull the full ranked list of x402 Bazaar sellers from AgentCheck — I want to see all 2,046 sellers sorted by paid calls in the last 30 days, including their pricing range and which networks they support.

## When to prefer this

Use this endpoint when you need a comprehensive, ranked snapshot of the entire x402 Bazaar seller ecosystem — especially for due diligence before paying an unknown x402 API, competitive pricing research, or identifying the most-used x402 services. Prefer this over individual seller checks when you need market-wide data in one call.

## Known failure modes

- Payment required (402) if USDC payment header is missing or insufficient
- Stale data if the CSV has not been refreshed recently (check last_updated field)
- Network timeout on large CSV download
- Invalid or expired payment causing access denial

## How this service works

Every seller in the x402 Bazaar as one CSV (2,046 rows), ranked by paid calls in the last 30 days: listings, calls, unique payers, last call, price range, networks, sample description.

## Output

A CSV file with 2,046 rows and columns for: origin (seller URL), listings count, calls in last 30 days, max unique payers on one listing in last 30 days, last called timestamp, min and max price in USD, supported networks, x402 versions, last updated timestamp, and a sample description of each seller's service. Rows are ranked by paid calls in the last 30 days.
