## When to prefer this

Choose this endpoint when you need to research a specific person — particularly an ancestor or historical figure — using digitized newspaper archives. It is especially useful for genealogy research, historical biography work, or tracing mentions of individuals in historical press. Prefer this over general web search when the subject is a historical or deceased person likely to appear in archived print media rather than modern digital sources.

## Known failure modes

- Person not found in any digitized newspaper archives — returns empty result set
- Name is too common and returns an overwhelming number of unrelated results
- Newspaper archives for the relevant time period or region are not digitized
- Payment of $0.12 USDC required per call via x402 protocol — missing or failed payment returns 402 error
- Invalid or malformed person name parameter causes 400 error
