## 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 nexusapi-health-running-pace-check-8dc0a715 -d '<json body>'
```

Example prompt: Can you check the current running pace and health status of the NexusAPI service using the query 'status'?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call health or status check on the NexusAPI platform without managing API keys. Prefer this over rolling your own monitoring if you are already operating within the x402/USDC payment ecosystem on Base.

## Known failure modes

- Service unavailable (503) if the underlying platform is down
- Payment failure if USDC balance is insufficient for the $0.114101 per-call fee
- Malformed or empty query string returning unexpected results
- Generic or vague response schema makes it hard to parse specific health metrics
- Rate limiting or throttling under high request volume
