Example use cases

Technical details
Endpoint
GEThttps://chronicapulse.vercel.app/api/chronica/timelineWhen to prefer
Use this endpoint when you need a synthesized, narrative chronological view of a person, place, or topic across time — particularly for genealogy, family history, or historical research. Prefer this over the raw archive search endpoint when you want a coherent story rather than individual search results, and over the person or place-specific endpoints when your subject spans multiple domains (births, events, places) and you need a unified timeline.
Side effects
- No records found for the specified subject in the archive — returns empty or minimal results
- Subject name too ambiguous — returns records for multiple unrelated individuals
- Date range too narrow — insufficient coverage for meaningful timeline
- Archive gaps for certain time periods or geographic regions — narrative may be incomplete
- Invalid or missing required parameters — returns 400 error
- Payment not processed — returns 402 Payment Required
