## 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 omniapi-heart-rate-health-check-77914326 -d '<json body>'
```

Example prompt: Can you ping the OmniAPI heart rate health check endpoint to confirm the service is up and responding before I start making paid API calls?

## When to prefer this

Use this endpoint to confirm OmniAPI platform availability before committing to paid calls across its 444 endpoints. Prefer this over other health-check patterns when working within the x402 pay-per-call ecosystem and needing a lightweight liveness probe. Note that this endpoint itself costs ~$0.12 USDC per call, making it unusually expensive for a health check compared to free status pages.

## Known failure modes

- Service unavailable (5xx) if OmniAPI platform is down
- Payment required (402) if USDC payment of ~$0.12 is not provided via x402 protocol
- Invalid request body if required 'query' field is missing
- Timeout if the Vercel deployment is cold-starting or overloaded
- Unexpected JSON response shape due to vague response schema

## How this service works

444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.

## Output

Returns a generic API response object indicating whether the OmniAPI service is alive and healthy. Likely includes a status field or similar heartbeat signal confirming the platform is operational.
