## 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 openpay-japan-web3-directory-search-1f09e5ad
```

Example prompt: Search the Japan Web3 directory on OpenPay for merchants near Tokyo that accept JPYC or USDC payments so I can find a crypto-friendly restaurant or shop to order from.

## When to prefer this

Choose this endpoint when you need to discover Japan-based merchants that accept JPYC or USDC stablecoin payments via OpenPay's non-custodial infrastructure, especially when looking for AI agent payment-compatible or Web3-native businesses. Prefer this over generic business directories when the user specifically needs crypto/stablecoin-accepting vendors in Japan.

## Known failure modes

- Empty results if no merchants match the search query
- HTTP 402 if the $0.02 USDC micropayment is not fulfilled before the request
- HTTP 400 if query parameters are malformed or missing
- Rate limiting or timeout if the directory service is temporarily unavailable
- Stale listings if merchants have recently changed their payment support status

## How this service works

Filter the Japan Web3 Directory by category, token, chain or capability — the same sourced, date-stamped records as the full export, without pulling rows your agent doesn't need.

## Output

Returns a list of merchants registered in the Japan Web3 directory that are compatible with OpenPay's JPYC/USDC payment infrastructure, including merchant names, categories, payment method support, fee rates, and relevant contact or ordering details.
