## 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 artillerist-wallet-test-x402-trial-c53deaaf
```

Example prompt: Run the Artillerist x402 trial call to verify my USDC wallet on Base mainnet can complete a real micropayment before I start pulling production art data.

## When to prefer this

Use this endpoint as a low-cost ($0.001 USDC) preflight check before making any production calls to The Artillerist's paid art data endpoints. Prefer this when setting up a new agent wallet, debugging x402 payment failures, or validating that a Base mainnet USDC wallet is correctly integrated with the x402 v2 protocol. It is the canonical test call for the Artillerist ecosystem specifically.

## Known failure modes

- Insufficient USDC balance in wallet — payment cannot be completed
- Wallet not configured for Base mainnet — wrong network error
- x402 protocol version mismatch — v2 not supported by caller
- Payment facilitator unavailable — gateway timeout
- Invalid wallet address or private key configuration

## How this service works

Verify that an agent wallet can complete an x402 v2 payment using USDC on Base mainnet before purchasing production art data.

## Output

A confirmation response indicating whether the x402 v2 micropayment of 0.001 USDC on Base mainnet was successfully processed, allowing the caller to verify wallet compatibility and payment infrastructure before making production API calls.
