About NHDdata — California NHD + Tax API
from our crawl and measurement
NHDdata California NHD + Tax API is a business whose own site puts it this way: "One REST call returns FEMA flood, CAL FIRE FHSZ, CGS earthquake / liquefaction / landslide / tsunami, DWR dam inundation, CalGEM wells, plus decoded Mello-Roos / 1915 / PACE, for any." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 3.5 out of 10.
