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.

Clinical Calculator API
Standard clinical and nursing calculators as an API — the everyday medical maths, computed locally. The bsa endpoint computes body surface area from weight and height by the Mosteller, Du Bois and Haycock formulas (used for chemotherapy and drug dosing). The egfr endpoint estimates kidney function from serum creatinine, age and sex using the race-free CKD-EPI 2021 equation, and the Cockcroft-Gault creatinine clearance when a weight is given (creatinine in mg/dL or µmol/L). The drip-rate endpoint computes an IV infusion's drops per minute and millilitres per hour from the volume, time and drop factor. The gcs endpoint scores the Glasgow Coma Scale from its eye, verbal and motor components and gives the severity band. Everything is computed locally and deterministically, so it is instant and private. INFORMATIONAL ONLY — not medical advice; always verify with clinical judgement and approved tools. Ideal for healthcare and nursing apps, clinical decision-support prototypes, medical education, and EHR tooling. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is clinical maths; for drug reference data use a drug API and for BMI, BMR and calories use a health-calculator API.

RxNorm API
US drug terminology as an API, powered by the U.S. National Library of Medicine's RxNav / RxNorm service. Resolve any drug or medication name to its RxNorm concept identifier (RxCUI); read a concept's properties (preferred name, term type, synonym, UMLS id); find all the related drug products for a name grouped by term type (brand names, ingredients, clinical and branded drugs, dose forms); walk related concepts by term type; list the drug classes a medicine belongs to across ATC, VA, mechanism of action, physiologic effect and chemical structure; and run spelling-tolerant search that returns candidate RxCUIs with match scores for misspelled or partial names. The standardised vocabulary that underpins US electronic health records and e-prescribing. Ideal for EHR and pharmacy systems, medication reconciliation, clinical-decision-support and health apps, and drug-data normalisation pipelines. RxCUIs are numeric.

ICD-10 Codes API
The ICD-10-CM diagnosis code system as an API — 71,000+ International Classification of Diseases (10th revision, Clinical Modification) codes used in healthcare, billing and insurance. Look up any code (e.g. E11.9 → Type 2 diabetes mellitus without complications), search the classification by condition, or browse every code in a 3-character category. Ideal for EHR/EMR systems, medical billing, claims and health-tech tooling.

WordPress Directory API
The official WordPress.org plugin and theme directory as an API — the registry behind the ~40% of the web that runs on WordPress. Look up any plugin or theme by its slug for its name, version, author, user rating and rating count, active-install count and total downloads, the WordPress and PHP versions it requires, last-updated date, homepage, support URL and direct download link; and search the directory by keyword (plugins or themes), with results ranked by active installs. Covers the 60,000+ free plugins and 13,000+ themes on WordPress.org, from WooCommerce, Yoast SEO and Elementor to Contact Form 7 and Jetpack. Live from the official api.wordpress.org. Ideal for WordPress dashboards and site managers, plugin/theme catalogs, compatibility and update tooling, and the WordPress developer ecosystem. Open data from WordPress.org.
