## 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-holders-overlap-3730def6 -d '<json body>'
```

Example prompt: Can you check the holder overlap between 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and 0x6B175474E89094C44Da98b954EedeAC495271d0F on Base, and flag any known insider addresses among the shared holders?

## When to prefer this

Use this endpoint when you need to find cross-token wallet overlap on-chain — especially to detect coordinated holdings, insider activity, or shared investor bases between two specific tokens. Prefer this over generic blockchain explorers when you need both structured tabular data and a natural language investigation summary in a single call, and when paying per-call via x402/USDC on Base is acceptable.

## Known failure modes

- Invalid or unrecognized token addresses return an error or empty result
- Tokens on unsupported chains will not return data
- Insufficient USDC balance for x402 payment causes the request to be rejected
- Very new tokens with sparse on-chain data may return incomplete holder sets
- Rate limiting or node congestion may delay responses

## How this service works

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

## Output

Returns a list of wallet addresses holding both tokens, each with their balance and percentage of total supply, plus a natural language summary noting the total number of shared holders and which among them are known insider addresses. Also includes a request ID for traceability.
