## 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 heurist-mesh-usdc-top-funders-forensics-cc4ff266 -d '<json body>'
```

Example prompt: Can you show me the top 20 wallets that have been sending USDC to 0x4e5F9B1dA33A8D8A36b06A2C3B370e80d64d0D78? I want to see if there are any dominant funders or controller wallets concentrating the inflows.

## When to prefer this

Use this endpoint when you need to investigate the funding sources of a specific wallet address on Base network using USDC, particularly for forensic analysis, anti-money-laundering checks, detecting coordinated funding, or identifying controller/hub wallets. Prefer this over generic transaction endpoints when you specifically want aggregated inflow statistics ranked by volume or frequency from unique sender addresses.

## Known failure modes

- Invalid or malformed wallet address returns validation error
- Address with no USDC inflows returns empty funder list
- Network or RPC errors may cause lookup failure
- Rate limiting or payment failure for the $0.005 USDC per call fee
- Very new addresses with no on-chain history return empty results

## How this service works

Identify the top source wallets that send USDC to the target address, including counts, total volume, and time range. Use to detect concentrated funding patterns and surface potential hub/controller wallets.

## Output

Returns a ranked list of up to N source wallets that have sent USDC to the target address, including each sender's wallet address, number of transactions, total USDC volume sent, and the time range of activity — enabling identification of concentrated funding patterns or potential hub/controller wallets.
