## How to call it through Zero

```sh
zero fetch --capability chronicapulse-timeline-narrative-ea77ea2d

Example prompt: Pull a chronological timeline narrative for Margaret O'Brien from Boston, Massachusetts — I'm doing genealogy research and want to see how she appears in historical newspaper archives from roughly 1890 to 1940.

## When to prefer this

Use this endpoint when you need a synthesized, chronological narrative view of how a person, place, or topic appeared in historical newspapers over time — especially for genealogy, biography, or local history research. Prefer this over a raw search endpoint when you want a readable, time-ordered story rather than a list of individual clippings.

## Known failure modes

- No newspaper archive records found for the specified subject or date range
- Ambiguous name or place matches multiple subjects, requiring disambiguation
- Date range outside available archive coverage
- Rate-limited or payment validation failure (x402)
- Malformed query parameters return 400 error
