Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 kronos-market-intelligence-whale-alert-feed-by-coinopai-74c089b8
```

Example prompt: Pull the whale alert feed for Base over the last 4 hours — I want to see any large exchange inflows or outflows and how many alerts fired.

## When to prefer this

Choose this endpoint when you need raw, timestamped whale movement alerts for a specific chain over a flexible lookback window — particularly when you want exchange-level granularity (venue + direction + USD value) rather than aggregated risk scores or forecast ranges. It is the right choice for pre-trade due diligence, ecosystem monitoring, or feeding whale signals into a downstream decision workflow. Prefer sibling endpoints for go/no-go gating, calibrated confidence scoring, or historical signal backtesting.

## Known failure modes

- Invalid chain value (not ethereum/base/arbitrum) returns a validation error
- Hours parameter outside 1-168 range returns a schema validation error
- Payment not settled via x402 returns HTTP 402 requiring micropayment
- No whale activity in the requested window returns an empty alerts array with alert_count 0
- Network or upstream data provider outage may return 503 or timeout

## How this service works

Auditable market context with calibrated crypto forecast ranges, risk state, decision journaling, and post-decision audit via x402 micropayments on Base.

## Output

A JSON object containing the queried chain name, the time window in hours, a count of alerts fired, and an array of alert objects each specifying the alert type (e.g. exchange_flow), the venue (e.g. Coinbase), the direction of funds (in/out), and the USD value of the movement.
