## How to call it through Zero

```sh
zero fetch --capability argon-verifier-evm-wallet-dossier-14cea92b
```

Example prompt: Can you pull the on-chain due-diligence dossier for the wallet 0x742d35Cc6634C0532925a3b8D4C9A3e6b4c4F1d2? I want to know if it looks risky before I send funds.

## When to prefer this

Choose this endpoint when you need per-call, pay-as-you-go on-chain due diligence for EVM wallet addresses without a subscription, especially when failed lookups should not cost anything. Ideal for agents that need to spot-check wallet risk before executing transactions, onboarding users, or verifying counterparties in a DeFi or crypto compliance context.

## Known failure modes

- Invalid address format (not matching ^0x[0-9a-fA-F]{40}$) — returns error, not charged
- Address not found or no on-chain data — returns error, not charged
- x402 payment failure or insufficient USDC balance — request not processed
- Cloudflare Worker timeout or upstream data provider unavailability — service error

## How this service works

On-chain due-diligence reports paid per call over x402 (USDC on Base or Solana). Failed lookups are never charged.

## Output

A JSON on-chain due-diligence dossier for the queried EVM wallet address, potentially including transaction history signals, risk indicators, wallet age, known labels, and activity patterns. The call is only charged (0.05 USDC via x402) when the lookup succeeds; failed lookups are not billed.
