## 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 atlasmarkets-whale-tracking-12d96c3b
```

Example prompt: Pull the latest whale flow data for BTC and ETH — I want to see what large holders have been moving on-chain recently.

## When to prefer this

Choose this endpoint when you need real-time on-chain whale flow data specifically for BTC and ETH and are comfortable paying micro-fees via x402 on Base mainnet. Prefer this over social-media-based whale trackers when you need verifiable on-chain movement data rather than inferred activity.

## Known failure modes

- Payment not included or insufficient — endpoint returns 402 Payment Required if x402 payment header is missing or underfunded
- Invalid or unsupported asset symbol — may return 400 if a non-BTC/ETH asset is requested
- Upstream blockchain data unavailable — may return 503 if the on-chain data provider is temporarily unreachable
- Rate limiting — repeated rapid calls may be throttled
