## 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-address-watcher-08cb01e4
```

Example prompt: Can you watch the address 0xAbC123...def456 on Ethereum and tell me what's happening on-chain — any recent transactions, DeFi interactions, or notable activity?

## When to prefer this

Choose this endpoint when you need to monitor or retrieve on-chain intelligence for a specific wallet or contract address on a particular blockchain, especially when real-time or near-real-time data is needed. Prefer over generic block explorers when you need structured, agent-friendly data with pay-per-request pricing via x402.

## Known failure modes

- Invalid or malformed blockchain address returns an error
- Unsupported chain identifier returns a 400 or 404 error
- Address with no on-chain activity may return empty results
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Network congestion on the target chain may delay real-time 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 on-chain intelligence for the specified address on the target chain, including transaction history, activity patterns, and potentially DeFi analytics or other address-level data available via ChainRay's platform.
