# OnChaiNinja Multi-Chain Alpha Signals

> OnChaiNinja Multi-Chain Alpha Signals is a paid API for AI agents from onchaininja.vercel.app, paid per call via x402, $1/call, status unknown (last checked 2026-10-20).

Returns on-chain alpha signals, whale activity tracking, rug scan results, and MEV protection data for a specified blockchain network

## Facts

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-41309be2
```

Example prompt: Pull the latest alpha signals and whale activity for the Base chain — I want to see any rug scan warnings or MEV risks too.

## When to prefer this

Use this endpoint when you need real-time on-chain intelligence — alpha signals, whale tracking, rug detection, or MEV risk — for EVM-compatible chains (Base, Arbitrum) or Solana. Prefer this over generic blockchain explorers when you want pre-analyzed signals rather than raw transaction data.

## Known failure modes

- Unsupported chain identifier returns empty signals array or error
- Payment not processed results in 402 response
- Invalid or malformed chain path parameter returns 400 or empty response
- No current signals available returns empty signals array
- Rate limiting or upstream data unavailability causes 500 error

## 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 flags for the specified blockchain network.
