```

Example prompt: Can you check if the Channel3 service is currently up and healthy?

## When to prefer this

Use this endpoint when you need to verify that the Channel3 service is up and available before making downstream calls to its brand, product, or category endpoints. Prefer this over general HTTP probing when you specifically need Channel3 operational status.

## Known failure modes

- Channel3 backend is down — returns unhealthy or error status
- Network timeout if Channel3 service is unreachable
- Unexpected response format if Channel3 API version mismatch
- 402 payment required if USDC payment not provided
