## 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 oracle-swarm-vault-whale-movement-alert-2964bdf4 -d '<json body>'
```

Example prompt: Check for whale movement alerts on PEPE right now — I want to know if any large wallets have made significant buys or sells recently, and give me the confidence score and a plain-English summary of what happened.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call (no API key required) signal about large on-chain token movements, especially for memecoins and DeFi tokens on Base-compatible networks. It is well-suited for AI agents that need real-time whale intelligence without a subscription, paying only $0.01 USDC per call via x402 micropayments. Prefer alternatives if you need historical whale data over long time ranges, multi-chain aggregation, or structured order-book data.

## Known failure modes

- No recent whale activity detected for the requested token — returns low score with minimal result text
- Invalid or unrecognized token address — may return an error or empty result
- Payment failure via x402 micropayment — request rejected before processing
- Rate limiting or network congestion on Base blockchain — delayed or failed response
- Token not supported or insufficient on-chain liquidity data — low-confidence result
