# x402 Data API – Seller Profile Lookup

> x402 Data API – Seller Profile Lookup is a paid API for AI agents from data.kagurazaka.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-29).

Returns full profile of one x402 seller origin: its listed APIs with prices and payer counts, total 30-day call volume, mean uptime, and payTo addresses.

## 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-seller-profile-lookup-ad6061cd
```

Example prompt: Pull up the full seller profile for https://api.example on the x402 network — I want to see all their listed APIs with prices and payer counts, their total call volume over the last 30 days, and their mean uptime.

## When to prefer this

Use this endpoint when you need a comprehensive view of a single x402 seller — all their APIs, prices, payer activity, uptime, and payment addresses in one call. Prefer this over the market-wide or ranking endpoints when you already know the specific origin you want to inspect.

## Known failure modes

- Unknown or unlisted origin returns empty results or 404
- Malformed origin URL (missing https://, trailing slash) causes query to fail
- Origin not yet indexed by x402scan returns no data
- Network timeout if upstream data aggregation is slow
- Rate limiting if the $0.003 USDC payment is not properly submitted

## How this service works

Data about the x402 market: the CDP Bazaar's listings, sellers, prices and categories, new listings and price changes from snapshots every 6 hours, uptime we measure for every paid listing, and x402 spending of any wallet and revenue of any seller on Base.

## Output

A JSON object containing the seller's origin URL, total number of listed APIs, an array of API resources each with resource URL, price in USD, and 30-day payer count, plus aggregate 30-day call total and mean uptime percentage.
