## When to prefer this

Choose this endpoint when you need to verify that the Turbo Gateway's x402 payment protocol integration is functional, or when probing the AR.IO Arweave network's micropayment capability before committing to upload or download operations. Not suitable for actual data uploads or large egress operations.

## Known failure modes

- Gateway may return 500 if the AR.IO backend is unavailable
- Network timeout if turbo-gateway.com is unreachable
- Invalid or expired x402 payment token results in rejection
- Rate limiting may return 429 if probed too frequently

## Output

An HTTP response (likely 200 or 402) from the Turbo Gateway's x402 test route, indicating whether the payment protocol handshake is functional and the gateway is operational on the AR.IO Arweave network.
