## 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 evm-wallet-reputation-risk-scoring-4111d67d -d '<json body>'
```

Example prompt: Can you check the on-chain reputation and risk score for the wallet address 0x1234abcd...5678 before I send any funds to it?

## When to prefer this

Use this endpoint when an AI trading or DeFi agent needs to vet an EVM counterparty wallet before executing a transaction, providing liquidity, or sending assets — especially when real-time on-chain reputation data is needed without setting up API keys or subscriptions. Prefer this over manual block-explorer lookups or static blocklists when you need a programmatic, scored risk signal at call time, paid per-use in stablecoins.

## Known failure modes

- Invalid or malformed 0x address returns a validation error
- Unrecognized or brand-new wallet with no on-chain history may return a low-confidence or neutral score
- Payment failure (insufficient USDC balance) blocks the call with a 402 response
- Network timeouts from underlying chain data providers
- Rate limiting if many calls are made in rapid succession

## How this service works

Wallet reputation: objective on-chain trust signals for an EVM address (vet a counterparty before dealing). Send { address }.

## Output

Returns a risk and reputation score for the given EVM wallet address, including behavioral signals, trust indicators, and flags for suspicious or high-risk on-chain activity that an agent can use to decide whether to proceed with an interaction.
