## 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 sleuth-ai-find-side-wallets-11875173 -d '<json body>'
```

Example prompt: Can you find the side wallets and linked addresses associated with 0x1234567890abcdef1234567890abcdef12345678 — I want to know which wallets are connected to it and how they're related?

## When to prefer this

Use this endpoint when you need to identify wallet clusters, side wallets, or linked addresses for a specific blockchain address — particularly for fraud investigation, compliance checks, or due diligence. Prefer this over generic blockchain explorers when you need AI-interpreted relationship mapping rather than raw transaction history.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unknown or unindexed wallet address may return empty results
- Insufficient USDC balance for x402 payment causes the call to fail
- Rate limiting or network issues may cause timeouts
- Address with no on-chain activity may return no linked wallets

## How this service works

Pay-per-call on-chain investigation API (x402, USDC on Base).

## Output

Returns a structured JSON response with a natural language summary of findings and a data node containing discovered side wallets or linked addresses, including wallet addresses, relationship descriptors, balance data, and a summary of largest holders or controllers. Also includes a request ID for reference.
