Technical details
Endpoint
GEThttps://chronicapulse.theaslangroupllc.com/api/chronica/immigration?utm_source=zero.xyzWhen to prefer
Use this endpoint when researching an ancestor's immigration journey, arrival records, or naturalization history, or when looking for historical ethnic press and immigrant community newspaper coverage. Prefer this over the general person research endpoint when the specific focus is on immigration events, ship manifests, passenger lists, or immigrant community context rather than a broader biographical profile.
Side effects

- Records for requested time period or origin country not indexed — partial or no results
- Invalid or malformed query parameters — returns 400 error
- Payment not processed — returns 402 payment required
- Rate limit exceeded — returns 429 error
