## 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 wraith-whale-signals-automated-whale-alert-feed-cee34497
```

Example prompt: Pull the latest whale alert signals right now so my trading bot can see which large orders are forming and which side the whales are on.

## When to prefer this

Choose this endpoint when you need a clean, automated, machine-readable whale alert feed delivered in real-time for bot or algorithmic trading use, specifically focused on large-order print signals as they form — rather than historical analysis, full multi-domain signal aggregation, or funding/OI data (use sibling endpoints for those).

## Known failure modes

- Payment failure (x402 protocol not satisfied) — returns 402 Payment Required
- Stale data if upstream aggregation is delayed — feed may lag real-time by seconds
- Empty or minimal results during low-volatility periods with few qualifying whale prints
- Rate limiting or worker timeout on the Cloudflare Workers edge — returns 5xx error
- Malformed response if the upstream data source is unavailable

## How this service works

The automated whale-alert feed: same clean signal data, delivered fresh and machine-readable so your bot can act on the move while it is still forming

## Output

Returns a fresh, machine-readable JSON feed of automated whale trade alerts, including key fields such as symbol, side (buy/sell), price, size, and USD notional for large orders detected in crypto markets, formatted for direct bot consumption.
