## 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 alf-counterparty-check-solana-wallet-risk-screener-8335e53c -d '<json body>'
```

Example prompt: Before I trade with this wallet, can you run a counterparty check on 8xFdK3jP2mNqRvTuWbLzYhCsA9oEpGkXeDwViQlUmTn to see if they're a dumper, bot, or clean?

## When to prefer this

Choose this endpoint when you need a fast, single-call risk classification of a Solana wallet before engaging in a trade, NFT sale, DeFi transaction, or any on-chain deal — especially when you want a human-readable verdict (bot/dumper/launcher/clean) rather than raw on-chain data you'd have to interpret yourself.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error
- Wallet with no on-chain history may yield an inconclusive or limited verdict
- Network or service downtime returns a non-ok response
- Payment failure via x402 prevents the check from executing
