## 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-b52415d6
```

Example prompt: Pull this week's whale intent report — I want to know what Claude thinks the big $100K+ on-chain movers are actually trying to do right now.

## When to prefer this

Choose this endpoint when you need AI-interpreted intent behind large crypto wallet movements rather than raw transaction data. Ideal for agents performing weekly crypto market intelligence, DeFi sentiment analysis, or monitoring institutional-scale on-chain behavior. Prefer this over raw blockchain explorers when narrative reasoning about whale motivation is more valuable than raw numbers.

## Known failure modes

- Payment not received — 402 response if $0.5 USDC not provided via x402 protocol
- No whale transactions detected in the current week — empty or minimal report
- Claude inference unavailable — upstream AI provider outage
- Stale data — weekly cadence means intra-week movements may not yet be included
- Rate limiting or Vercel cold-start latency causing timeout
