## How to call it through Zero

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

```sh

```

Example prompt: Search the digitized newspaper archives for any mentions of 'Heinrich Braun' from Bavaria between 1880 and 1920 — I'm trying to trace my great-great-grandfather for a genealogy project.

## When to prefer this

Use this endpoint when you need a broad, keyword-based full-text search across multiple global newspaper archives simultaneously, rather than searching for a specific entity type (person, place, business). Ideal as a starting point for genealogy or historical research when the researcher wants to cast a wide net before using more targeted sibling endpoints like person search, obituary, or military history lookups.

## Known failure modes

- No results found for the given query or date range — returns empty result set
- Query too broad returns excessive results with low relevance
- Archive coverage gaps for certain regions or time periods may yield no matches
- Invalid or malformed query parameters return an error response
- Rate limiting or payment failure prevents the request from completing
