## 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-cex-flows-cex-attribution-api-6e5ad89b -d '<json body>'
```

Example prompt: Can you tell me which centralized exchange this wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE is associated with — like whether it's a Binance or Coinbase deposit address?

## When to prefer this

Use this endpoint when you need to determine which centralized exchange (CEX) a specific crypto wallet address is associated with, particularly for exchange deposit attribution, compliance checks, on-chain KYC enrichment, or understanding fund flows between wallets and exchanges. Prefer this over generic blockchain explorers when you need structured, machine-readable CEX attribution evidence with provenance.

## Known failure modes

- Wallet address not found or unattributable — returns null attribution or low-confidence result
- Invalid wallet address format — returns error
- Payment of 0.05 USDC on Base not completed — returns 402 Payment Required
- Rate limiting or quota exceeded — returns 429
- Wallet is a self-custodial or DeFi address with no CEX deposit linkage — returns no attribution
