## 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 x402-whale-intent-decoder-63528315
```

Example prompt: There's a whale alert for a $2.5 million USDC transfer from a Binance wallet to a cold wallet — can you decode what the likely intent or motive behind this move is?

## When to prefer this

Use this endpoint when you need AI-driven qualitative interpretation of large on-chain crypto movements rather than raw transaction data. Ideal for traders, analysts, or bots that want to understand the 'why' behind whale activity, not just the 'what'. Choose this over raw blockchain APIs when narrative or intent classification is more valuable than raw numbers.

## Known failure modes

- No recent whale alert data available — returns empty or error response
- Insufficient transaction context to infer intent confidently
- x402 payment of $0.1 USDC not fulfilled — 402 Payment Required response
- Vercel cold start or timeout causing delayed response
- Claude API rate limit or outage preventing inference
