Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you decode the likely intent behind this whale transaction — a wallet just moved $2.3M USDC from Binance to a cold wallet on Ethereum? Use the Whale Intent Decoder to tell me what they're probably trying to do.

## When to prefer this

Choose this endpoint when you need AI-powered qualitative interpretation of large crypto transactions (>$100K) and want to understand the strategic intent or motivation behind whale movements, not just raw on-chain metrics. Prefer over generic blockchain explorers when you need natural language reasoning about transaction purpose.

## Known failure modes

- Transaction amount below $100K threshold may return insufficient data error
- Malformed or missing transaction data returns 400 bad request
- Claude API unavailability causes 503 service unavailable
- Ambiguous transaction data may yield low-confidence or generic intent inference
- Rate limiting or x402 payment failure blocks the request
