actually, no. The XAPI was really written to answer types of queries
where the API would not cope, or the API was not made for (give me every
node tagged as a phone booth on the entire world, for example)

T at H then started using it as a secondary datasource, because it started
loading the main API too much, only then the role of XAPI became more of
a load-reducing one for the main API.

TRAPI and ROMA were other offloading APIs that were made for uses such
as T at H, those, too, are limited in what kind of api calls they allow
("map" bboxes only, IIRC)
