## 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 chainray-chain-health-0b3bc228
```

Example prompt: What's the current health status of the Base blockchain — is it running normally right now?

## When to prefer this

Use this endpoint when you need to verify whether a specific blockchain network is operational before executing transactions, bridging assets, or querying on-chain data. Prefer this over generic status pages when you need structured, machine-readable health data for a specific chain from a service covering 46 chains with pay-per-use pricing.

## Known failure modes

- Unsupported chain identifier returns an error or empty response
- Network connectivity issues to ChainRay backend return 5xx errors
- Payment failure via x402 protocol returns 402 Payment Required
- Missing or malformed chain query parameter may return a default chain or error
- Chain temporarily unavailable may return degraded or stale data

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns real-time health and operational status of the requested blockchain network, including availability indicators, block production status, and any network-level issues detected across the monitored chain.
