## 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 x402-session-check-ping-all-services-90658988
```

Example prompt: Before I kick off my data pipeline, can you ping all the x402 services to make sure they're up and responding?

## When to prefer this

Use this endpoint as a pre-flight check before executing a multi-step workflow that depends on x402 services, or when diagnosing why x402 API calls are failing. Prefer this over calling individual service endpoints separately when you need to verify the entire x402 ecosystem at once.

## Known failure modes

- One or more x402 services are down — partial or degraded status returned
- Network timeout if Railway-hosted service is unresponsive
- Non-200 HTTP response if the API itself is offline
- Payment failure if the $0.02 USDC x402 payment is not processed correctly

## How this service works

Ping all x402 services in one call

## Output

Returns a status response indicating whether all x402 services (prices, weather, FX, news, gas, crypto dominance, fear/greed, ATH, etc.) are reachable and responding. Typically includes an overall health status and may include per-service availability details.
