First Street
Peer-reviewed property-level climate-risk provider (formerly First Street Foundation) scoring flood, fire, wind, heat, and air risk. Delivered as consumer-facing Risk Factor reports (riskfactor.com) and via three documented APIs -- Climate Risk API (point-level physical risk), Enterprise API (portfolio aggregation), and Raster Map API (peril raster layers). Free non-commercial lookups plus paid consumer subscriptions and enterprise quotes.
Address-to-climate-risk layer -- three documented REST APIs (Climate Risk, Enterprise, Raster Map) return point-level flood/fire/wind/heat/air risk as JSON plus PDF reports and raster tiles; a public pricing page and free non-commercial Risk Factor lookups aid evaluation, with enterprise access quote-based.
