## 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 cult-os-hacker-signal-feed-04c856a2 -d '<json body>'
```

Example prompt: Pull up to 15 hacker signals from the last 72 hours in the engineering category about WebAssembly using the Cult OS Hacker Feed.

## When to prefer this

Choose this endpoint when you need a curated, multi-source hacker/developer signal feed aggregated around specific categories (news, social, engineering, releases) with recency and keyword filtering — especially useful when you want a lightweight digest rather than raw search engine results or a single-source RSS feed.

## Known failure modes

- Empty items array if no signals match the query or category in the given time window
- sourceErrors populated if one or more upstream signal sources failed to respond
- staleSources populated if some sources returned outdated data
- limit out of range (below 1 or above 20) causes validation error
- sinceHours out of range (below 1 or above 168) causes validation error
- query string exceeding 120 characters rejected
- Payment failure via x402 protocol prevents access
