## 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 whale-memory-api-combined-whale-digest-d163e47a
```

Example prompt: Pull me the latest whale digest — I want to see what billionaires and hedge funds are holding in their 13F filings alongside the most recent insider buys and sells all in one shot.

## When to prefer this

Choose this endpoint when you need both institutional 13F holdings and insider transaction data in a single call rather than querying them separately. Ideal for building investment research workflows, stock screening agents, or portfolio monitoring systems that track smart money consensus. Prefer this over individual endpoints when efficiency matters and you want correlated whale signals without multiple round-trips.

## Known failure modes

- Upstream SEC EDGAR or OpenInsider data may be delayed or temporarily unavailable
- 13F filings are only published quarterly so holdings data may be up to 45 days stale
- Payment not processed or insufficient USDC balance resulting in 402 response
- Rate limiting if the endpoint is called too frequently
- Empty or sparse result if no significant activity occurred in the lookback window
