US Hospitals API

healthy 4,849 Subscribers

Search and filter more than 5,400 Medicare-certified hospitals across the United States and territories: filter by state, city, free-text name, hospital type (acute care, critical access, psychiatric, childrens, veterans and more), ownership category, whether the hospital offers emergency services, and the CMS overall star rating. Look up any hospital by its CMS facility id, and read metadata listing every state with its hospital count plus the available types and ownership categories for building filter UIs. Each record returns the facility id, name, full address, county, phone number, type, ownership, emergency-services flag and overall rating. Built on the official CMS Hospital General Information dataset. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for healthcare directories, patient-facing apps, insurance and care-navigation tools, and research.

Every endpoint accepts input via the query string or the request body and returns lean, predictable JSON with normalized address, coordinates, phone and website fields.

Vehicle Database API

Decode any Vehicle Identification Number (VIN) into a full, structured vehicle specification — make, manufacturer, model, year, trim, series, body class, vehicle type, drive type, doors, engine (cylinders, displacement, horsepower, configuration and primary/secondary fuel), transmission style, gross vehicle weight rating and the manufacturing plant (country, city, state, company). Partial VINs with wildcards are supported and an optional model year improves accuracy. The API also lists every vehicle make (optionally for a vehicle type such as car, truck or motorcycle) and all models for a given make and year. Backed by the official NHTSA vPIC database, with clean, predictable JSON and no raw-data wrangling. Every endpoint accepts input via the query string or the request body. Ideal for automotive marketplaces, insurance and fleet tools, dealer and parts catalogues, and vehicle-registration flows.

Plant Hardiness API

Work with USDA Plant Hardiness Zones: determine the hardiness zone for any location from its average annual extreme minimum temperature in Celsius or Fahrenheit (returning the zone code such as 6b, the zone number, subzone and the temperature range in both units), browse the complete reference of all 26 subzones from 1a to 13b with their temperature ranges and example regions worldwide, look up a single subzone by code, and find which common garden plants — fruits, vegetables, herbs, shrubs, trees, perennials, vines, bulbs, succulents and grasses — tolerate a given zone. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side computation (no third-party upstream), so responses are instant and always available. Ideal for gardening and plant-finder apps, AgTech and landscaping tools, nurseries and education.
