## 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 wallet-revenue-authenticity-scorer-2fde58ea
```

Example prompt: Can you check if the revenue for wallet 0x1234...abcd on the x402 network looks real — use the last 60 days of on-chain Base USDC history to score it for fake payers, self-pay, or round-trip patterns?

## When to prefer this

Choose this endpoint when you need on-chain revenue fraud detection specific to x402 protocol seller wallets on Base USDC — particularly when evaluating whether an API seller's payment history reflects genuine market demand versus self-inflated or wash-traded revenue. Prefer this over generic blockchain explorers when you need a structured authenticity score rather than raw transaction data.

## Known failure modes

- Invalid EVM address format returns a validation error
- Address with no on-chain USDC activity returns empty or zero-score result
- Days parameter outside 1-90 range is rejected
- Wallet with very recent activity may have insufficient history for reliable scoring
- Node or chain data unavailability may cause timeout or partial results

## How this service works

Score whether an x402 seller wallet's revenue is real - distinct payers, repeat share, calls per payer, self-pay and round-trip flags, from Base USDC settlement history on chain.

## Output

Returns a structured authenticity score for the wallet's revenue including: number of distinct payers, share of repeat payers, average calls per payer, a boolean self-pay flag (wallet paying itself), and a round-trip flag (funds cycling back to sender), all derived from Base USDC settlement history over the requested time window.
