Nara class

final class Nara implements CivilRegistryInterface Nara.php:39

The National Archives Catalog of the United States (NARA), through its Catalog API v2: the federal records described file by file, many of them by the name of the person they are about - pension application files, compiled military service records, draft registration cards, indexes to naturalization papers, Indian census cards, homestead certificates, deceased personnel files... and, for a good share, their pages scanned.

It is a catalogue of federal archives, NOT civil registration: births, marriages and deaths are kept by the states and counties, and the Catalog holds none of them as such. Every record is therefore of the kind OTHER: a file that names the person, with its series, its record group and the reference room that holds it, and the links to its scanned pages at NARA (never copied). The Catalog dates a file by its series only: the span of the series is the record's period, not the date of an event.

A key is needed (header x-api-key; ask Catalog_API@nara.gov), 10,000 calls a month per key: past it, the key is blocked until the first of the next month. Without a valid key the API answers the Catalog's HTML page with a 200, which is read as unavailable.
