Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Pull me the top 10 crypto engineering signals from the last 24 hours using Cult OS's crypto feed — filter by the 'engineering' category.

## When to prefer this

Choose this endpoint when you need a pre-aggregated, multi-source crypto signal feed across categories like news, social chatter, engineering commits, or project releases — especially useful for agents that need structured intelligence without building their own crypto data pipeline. Prefer over raw RSS or single-source APIs when breadth across 9+ sources matters.

## Known failure modes

- No items returned if no signals match the query or time window
- sourceErrors array populated if one or more upstream sources fail to respond
- staleSources list populated if cached data is older than expected
- limit exceeded if request value is above maximum of 20
- sinceHours out of range if value is below 1 or above 168
