## 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 onchaininja-multi-chain-alpha-signals-ff50159d
```

Example prompt: Pull the latest alpha signals and whale activity for the Base chain — I want to know if there are any rug risks or MEV threats I should be watching right now.

## When to prefer this

Use this endpoint when you need on-chain intelligence — alpha signals, whale tracking, rug detection, or MEV protection — for a specific blockchain like Base, Solana, or Arbitrum, especially when you want a single endpoint covering multiple DeFi risk categories in one call.

## Known failure modes

- Unsupported chain identifier returns empty signals array or error
- Missing chain path parameter results in 404
- Payment not processed results in 402 Payment Required
- Rate limiting if called too frequently
- Empty signals array returned when no recent activity detected for the chain

## How this service works

Alpha signals, whale tracking, rug scanning, and MEV protection across Base, Solana, Arbitrum, and more.

## Output

A JSON object containing the queried chain name and an array of alpha signals, which may include whale wallet movements, rug scan assessments, and MEV protection alerts for that chain.
