## 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 bazaar-ping-discovery-test-purchase-b349f470
```

Example prompt: Run the Bazaar Ping discovery test — spend $0.05 USDC on Base to grab the cosmic wallpaper JPG and confirm my x402 micropayment flow is working.

## When to prefer this

Choose this endpoint when you need a minimal-cost, real-money integration test for x402 micropayment flows, especially to verify that an AI agent can autonomously authorize and settle a $0.05 USDC on-chain payment and receive a digital asset in return. It is the cheapest available live test of paid content delivery over x402.

## Known failure modes

- Payment not confirmed on-chain — no asset delivered until settlement
- Insufficient USDC balance — transaction rejected before fulfillment
- Unsupported network — only Base, Polygon, Arbitrum, and Avalanche accepted
- Invalid format parameter — only 'json' is accepted
- Network congestion causing delayed settlement and delayed delivery
