Lite score
GET /v1/lite
Give it a location and nothing else. There is no peril list to build: every peril available on your key runs automatically in one call, including all the cat perils, and each comes back as a return period in years against fixed severity thresholds. Use the in-depth endpoint when you want to choose specific perils and receive the full distribution.
