# Heurist Mesh: USDC Top Funders (Solana BaseUSDCForensicsAgent)

> Heurist Mesh: USDC Top Funders (Solana BaseUSDCForensicsAgent) is a paid API for AI agents from mesh.heurist.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Identifies the top source wallets sending USDC to a target Solana address, with counts, total volume, and time range to detect funding concentration and potential hub/controller wallets.

## 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-solana-baseusdcforensicsagent-743b3e5e -d '<json body>'
```

Example prompt: Who are the top wallets sending USDC to the Solana address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU? I want to see counts, total volume, and the time range to spot any concentrated funding patterns.

## When to prefer this

Use this endpoint when you need forensic-level insight into who is funding a specific Solana wallet with USDC — particularly useful for detecting sybil clusters, identifying controller/hub wallets, or performing due diligence on unknown counterparties. Prefer this over generic transaction history endpoints when the specific question is about concentrated or suspicious USDC inflows on Solana.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error or empty result
- Address with no USDC inflows returns empty funders list
- Rate limiting or payment failure (x402 micropayment not processed) blocks the request
- Very new or low-activity address may return sparse or incomplete data
- Network timeouts for on-chain data retrieval on high-load periods

## 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 top source wallets that have sent USDC to the target Solana address, including each sender's wallet address, number of transactions, total USDC volume sent, and the time range covered by the data. Highlights concentrated funding patterns and flags potential hub or controller wallets.
