    census.gov/geo/maps-data/data/baf_description.html may or may not be helpful. Note that these files assign blocks to named places, not tracts. It's possible that a single tract can be split across multiple place names.

It is not possible with just the Decennial Census API, but a solution can be constructed with the Census's TIGERweb services.

In sketch, use TIGERweb REST service to get the geometry of a place, and then use that geometry with another TIGERweb REST service to get a list of tracts that intersect with a place, and then use the Decennial Census API to look up information about those tracts.

This is the road I took in this python library that allows queries of tracts, blockgroups, and blocks by place (or other arbitrary geometries).
