# CN402 X402 Revenue De-Wash Intelligence

> CN402 X402 Revenue De-Wash Intelligence is a paid API for AI agents from api.cn402.com, paid per call via x402, $4.99/call, status unknown (last checked 2026-09-15).

Analyzes on-chain USDC payment flows for an x402 payee to separate genuine organic customer demand from self-funded wash activity and circular payment rings

## 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 api-cn402-com-452fa1af
```

Example prompt: Check if the x402 payee address 0xAbC123... has real independent customers or is mostly wash — I want the de-washed organic customer count versus self-funded circular payment rings.

## When to prefer this

Use this endpoint when you need to audit the legitimacy of x402 micropayment revenue for a specific payee wallet — especially when evaluating whether an API listed on x402-compatible markets has genuine organic demand versus inflated self-funded metrics. Prefer this over generic blockchain explorers when you specifically need wash-detection logic with two-hop USDC tracing and pre-indexed x402 catalog payees.

## Known failure modes

- Invalid or unrecognized payTo address returns an error or empty result
- Payee has no indexed on-chain activity yet (not in weekly catalog) may return insufficient data
- USDC hop tracing limited to two hops — deeper rings may not be detected
- Network or on-chain data unavailability causes service timeout
- Payment of $4.99 USDC required per call — unpaid requests rejected with 402

## How this service works

De-washed x402 revenue intelligence. Pass payTo to get a payee real independent customer count versus self-funded wash. Traces on-chain USDC funding two hops to separate organic demand from circular self-payment rings and shared-funder clusters. Top catalog payees indexed weekly.

## Output

Returns the de-washed real independent customer count for the given payee, broken down against self-funded wash payments, circular payment ring clusters, and shared-funder groups, so the caller can assess genuine organic demand for that x402 address.
