## 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 scalpstream-crypto-staking-interest-yield-feed-a85b323d
```

Example prompt: Pull today's ScalpStream crypto staking-and-interest yield feed — give me the top 5 picks as of today with the disclaimer included.

## When to prefer this

Choose this endpoint when you need a curated, ranked snapshot of crypto staking and interest yield opportunities at a specific point in time, particularly if you want a research-publication-style output rather than raw on-chain data. Prefer this over generic DeFi data APIs when you want pre-ranked picks with editorial framing. It complements ScalpStream's other feeds (options, scalp, municipal) for a broader financial research suite.

## Known failure modes

- Invalid or future as_of date returns no results or an error
- Empty picks array if no qualifying yields meet publication thresholds
- Payment failure via x402 returns 402 status before data is delivered
- Malformed pick_count integer may result in truncated or default result set
- Stale data if the feed has not been updated since the requested date
