## 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 blockchainanalysis-io-kyt-know-your-transaction-screening-eb278b98 -d '<json body>'
```

Example prompt: Can you run a KYT check on Ethereum wallet 0x28c6...1d60? I need to know the risk level and what entity it's linked to before we process a payment to it.

## When to prefer this

Choose this endpoint when you need real-time, on-demand AML/KYT screening of a specific wallet or address before initiating or accepting a crypto transaction. It is especially suited for compliance-aware payment flows, DeFi onboarding, exchange deposit verification, or any scenario requiring a risk verdict with entity attribution across a broad set of blockchains (52 chains, 34 jurisdictions). Prefer this over batch analytics platforms when you need a fast, per-address decision with regulatory context baked in.

## Known failure modes

- Unsupported blockchain — chain identifier not among the 52 supported networks returns an error
- Unknown address — wallet has no transaction history or entity attribution, resulting in an UNKNOWN entity classification
- Invalid address format — malformed wallet address returns a validation error
- Payment failure — insufficient USDC balance or x402 payment rejection blocks the call
- Rate limiting — excessive call volume may trigger throttling

## How this service works

Screen wallets, analyze exchange accounts, and monitor transactions with regulatory context across 34 jurisdictions and 52 blockchains.

## Output

Returns a JSON object with the tool name ('kyt'), blockchain chain identifier, screened wallet address, a human-readable risk verdict (e.g. 'KYT risk: LOW · entity: Binance 14 (EXCHANGE)'), and a structured verdict object with entity classification and compliance details. Payment is confirmed via x402 protocol.
