## How to call it through Zero

```sh
zero fetch --capability chronicapulse-business-history-research-1ed4b794
```

Example prompt: Can you search the historical newspaper archives for any coverage of Schmidt & Sons Hardware Store in Cincinnati, Ohio from roughly 1880 to 1920? I'm trying to trace the business history for a genealogy project.

## When to prefer this

Choose this endpoint when you need historical newspaper-sourced evidence of a business's past — especially for genealogy research, family history projects, or tracing defunct local businesses and shops. Prefer this over general web search when the subject predates digital media and requires digitized print archive coverage.

## Known failure modes

- No archived newspaper coverage found for the specified business or time period
- Business name too generic to resolve to specific records
- Date range falls outside digitized archive coverage
- Location not specific enough to disambiguate results
- API returns 402 if payment is not properly handled via x402 protocol
