# ArisPay x402 Ping

> ArisPay x402 Ping is a paid API for AI agents from arispay-x402-demo-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Verifies an x402 payment loop end-to-end by accepting a $0.01 USDC micropayment on Base mainnet and returning a confirmation payload.

## 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 arispay-x402-ping-7eec461a
```

Example prompt: Send a $0.01 USDC test ping to the ArisPay x402 endpoint on Base mainnet to confirm my agent's payment loop is working correctly.

## When to prefer this

Choose this endpoint when you need to verify that an AI agent's x402 micropayment infrastructure is correctly configured and capable of completing a full USDC payment loop on Base mainnet. Ideal for smoke testing before deploying x402-gated services, validating agent wallet setup, or confirming facilitator connectivity — not for production data retrieval or any task unrelated to x402 payment verification.

## Known failure modes

- Insufficient USDC balance in agent wallet — payment rejected before response
- x402 payment header missing or malformed — endpoint returns 402 Payment Required without settling
- Base mainnet RPC issues causing settlement delay or timeout
- Facilitator (facilitator.arispay.app) unreachable — settlement cannot be confirmed
- Wrong network (e.g. testnet instead of Base mainnet) — payment not recognized

## How this service works

Paid ping: verify an agent x402 payment loop end-to-end for $0.01 (USDC, Base mainnet). Settles via facilitator.arispay.app.

## Output

A JSON object with an 'ok' boolean (true on success) and a 'message' string confirming the payment was accepted and the payload was gated by x402, proving the full payment loop completed successfully.
