Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-67c86e69
```

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

## When to prefer this

Use this endpoint when an agent needs real-time on-chain intelligence — alpha signals, whale tracking, rug detection, or MEV risk — for a specific supported chain (Base, Solana, Arbitrum, etc.). Prefer this over general crypto price APIs when the user wants behavioral or risk-oriented chain analytics rather than spot prices.

## Known failure modes

- Invalid or unsupported chain identifier returns empty signals array
- Payment of $1 USDC not fulfilled results in 402 Payment Required
- Network timeout if the chain data provider is unavailable
- Empty signals array returned when no notable on-chain activity is detected

## 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 verdicts, and MEV protection alerts for that chain.
