9 Best APIs for Health in Nigeria

Netapps Insurance-as-a-Service (IaaS) API is a Nigerian insurance technology platform that enables fintech companies, banks, and digital businesses to embed insurance products directly into their applications without building insurance infrastructure or obtaining independent insurance licenses. Netapps provides API access to a portfolio of insurance products spanning health, auto, life, agriculture, travel, and device insurance, allowing any Nigerian digital platform to become an insurance distribution channel through a simple API integration. The Insurance-as-a-Service model that Netapps provides solves a fundamental distribution challenge in Nigeria's insurance market. Nigeria has one of the world's lowest insurance penetration rates — under one percent of GDP compared to global averages of 6-7 percent — due to limited distribution reach, low trust in insurance institutions, and products that are not well-suited to Nigerian consumer payment patterns and income levels. Embedding insurance into the digital platforms where Nigerians already transact creates distribution scale that traditional insurance agents cannot achieve. Fintech companies and neobanks are the primary integration targets for Netapps IaaS. A Nigerian neobank with millions of customers can use the Netapps health insurance API to offer hospital cash benefits, HMO plan access, or accident insurance directly within the banking app's product suite. The customer enrolls, pays their premium from their bank wallet or account, and receives their policy without leaving the app they already use daily. This distribution model increases insurance uptake by removing the friction of a separate insurance purchase journey. Health insurance products available through Netapps IaaS enable platforms to offer hospital admission cover, outpatient benefits, maternity coverage, and wellness benefits to their users. For a Nigerian salary advance app, HR platform, or savings product that serves employed Nigerians, embedding group health coverage or hospital cash products creates a differentiated product that increases retention and customer value beyond the core financial service. Auto insurance is compulsory in Nigeria under the Motor Vehicles (Third Party Insurance) Act, yet a significant proportion of vehicles on Nigerian roads remain uninsured due to friction in purchasing formal policies. The Netapps auto insurance API enables digital platforms — ride-hailing services, vehicle financing apps, fleet management platforms, and motor spare parts retailers — to embed third-party vehicle insurance at point of sale or vehicle registration, eliminating the friction that leaves millions of vehicles uninsured. Agricultural insurance through Netapps IaaS enables agritech platforms serving Nigerian farmers to bundle crop and livestock insurance with their input financing, advisory, and market linkage services. Agricultural insurance is especially important for Nigerian smallholder farmers who face catastrophic income loss from drought, flooding, pest outbreaks, and other production risks. Embedding insurance into the credit and advisory relationship that agritech platforms have with farmers creates a natural channel for agricultural risk management products. Device insurance through Netapps IaaS enables e-commerce platforms, smartphone retailers, and fintech apps offering device financing to bundle device protection at point of purchase or loan disbursement. With smartphone penetration growing rapidly in Nigeria and devices representing significant one-time expenditures for many consumers, device insurance tied to the purchase moment addresses a genuine consumer need at the point where it is most relevant. The Netapps API uses RESTful architecture with JSON request and response formats, following standard patterns for developer integration. Authentication uses API key-based access for production environments with sandbox credentials available for development and testing. Policy issuance, premium collection, and claims initiation are all supported through the API, enabling fully automated insurance workflows within integrating platforms without manual insurance company involvement for standard cases.

OpenWeather Air Pollution and UV API is a specialized subset of the OpenWeatherMap platform that provides real-time and forecast air quality data including pollutant concentrations, Air Quality Index values, and UV index measurements for any location worldwide. As air quality concerns grow in Nigerian cities driven by vehicle emissions, industrial activity, open burning, and seasonal Harmattan dust storms, this dedicated air quality and UV data endpoint enables Nigerian health apps, environmental platforms, and smart city projects to integrate pollution monitoring features beyond standard weather data. The Air Pollution API returns concentrations of major pollutants: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2), fine particulate matter (PM2.5), coarse particulate matter (PM10), and ammonia (NH3). Each pollutant reading is given in micrograms per cubic meter, and the response includes an overall Air Quality Index (AQI) on a 1-5 scale (1=Good, 2=Fair, 3=Moderate, 4=Poor, 5=Very Poor). Nigerian health tech developers building pollution alert apps can use these granular pollutant readings to give targeted advisories — for example, warning asthma patients specifically when NO2 and PM2.5 are elevated, which is common near Lagos highways and industrial areas. Historical air pollution data is available through the Air Pollution History endpoint, allowing retrieval of past pollution levels for any location with a Unix timestamp range. Nigerian researchers studying the relationship between air pollution episodes and respiratory disease hospitalizations, or environmental lawyers building evidence of industrial pollution near communities, can use this historical endpoint to retrieve pollution records spanning months or years. UV Index data from the UV endpoint returns current UV Index value and time of day, along with daily forecast UV Index maximum and hourly UV progression through the day. UV radiation levels in Nigeria are high year-round due to the country's equatorial location, with UV Index values frequently reaching 8-11 (Very High to Extreme) during midday hours. Nigerian health apps promoting skin cancer awareness, outdoor workers' safety apps, and tourism platforms can integrate UV Index data to advise users on sunscreen application and shade-seeking during peak UV hours. Forecast capabilities of the Air Pollution API extend 5 days into the future with 3-hourly pollution forecasts for any location. Nigerian event planners organizing outdoor festivals or sports events can check forecast air quality before finalizing dates, and Nigerian health authorities can anticipate poor air quality episodes in advance to issue proactive public health advisories. During Harmattan season (November to March), when Sahelian dust dramatically elevates PM10 readings across northern Nigeria, the pollution forecast capability is particularly valuable. The Air Pollution and UV API uses the same OpenWeatherMap API key as the standard weather endpoints, making it easy for Nigerian developers already using OpenWeatherMap for weather data to add air quality and UV features without any additional registration. The free tier includes 1,000 calls/day shared across all OpenWeatherMap endpoints, and the air quality endpoints count toward this shared daily limit. Paid plans increase call limits and are priced the same as the broader OpenWeatherMap subscription, making it cost-efficient to bundle weather, air quality, and UV data under one account. Nigerian developers already on OpenWeatherMap can enable air quality and UV data immediately with no additional API key setup required.

Wger Workout Manager API provides exercise database, muscle targeting information, and equipment data. The service is completely free and open source. Features include exercise descriptions, muscle groups, equipment details, and workout programs. Ideal for building fitness and workout applications.

The Open Disease API, also known as disease.sh, is a free and open-source disease tracking API that aggregates global epidemiological data from authoritative public health sources and exposes it through clean, well-documented REST endpoints. Originally built to provide accessible COVID-19 data during the pandemic, the API has expanded to cover multiple infectious diseases and serves as a reliable free data layer for public health applications, research platforms, and health monitoring dashboards worldwide. The API aggregates data from sources including the Johns Hopkins University CSSE COVID-19 dataset, the Worldometer disease tracker, Our World in Data vaccination records, and official national health ministry reports. By normalizing data from these disparate sources into a consistent JSON format, the API saves developers the substantial effort of building and maintaining their own data collection pipelines. Updates occur multiple times daily to keep case counts, death tolls, and recovery figures as current as possible. Global COVID-19 data is the most comprehensive dataset. The API provides summary totals for worldwide cases, deaths, recoveries, and active infections as well as the same breakdown for individual countries. Each country record includes current totals alongside daily new case and death figures, enabling developers to calculate trends and display whether the situation in a given country is improving or worsening. The data is available in multiple aggregation levels: global totals, continent-level summaries, country-level breakdowns, and for the United States, state-level granularity. For Nigeria specifically, the API provides country-level COVID-19 statistics sourced from official Nigerian Center for Disease Control reports and aggregated through the API's data partners. Nigerian public health applications, university research tools, and news platforms can access authoritative case and death figures without needing to build their own NCDC data scrapers or manually maintain databases. The availability of historical daily figures enables trend analysis showing Nigeria's pandemic trajectory over time. Vaccination data is included for countries that have reported vaccination progress, showing doses administered, people vaccinated with at least one dose, and fully vaccinated population percentages. For Nigerian health advocacy organizations, government agencies, and researchers monitoring Nigeria's COVID-19 vaccination campaign, this data provides standardized metrics comparable to other African nations and global benchmarks. Beyond COVID-19, the API provides data on influenza and, through integration with WHO data sources, general infectious disease surveillance information. As Nigeria and West Africa have historically been affected by Lassa fever, Monkeypox, cholera, and other endemic diseases, the availability of a free API that can be extended to additional disease tracking use cases makes disease.sh a valuable long-term infrastructure choice for Nigerian health application developers. The API requires no authentication and imposes no documented rate limits, making it completely accessible for developers at any stage from student projects through production applications. The entirely open-source codebase is hosted on GitHub, enabling self-hosting for organizations that require guaranteed uptime and data control. The lack of dependency on commercial data licensing also means the data can be displayed publicly without copyright concerns, which is important for Nigerian media organizations building public health dashboards. For NGOs operating health programs across Nigeria and West Africa, the API provides standardized health data that can populate monitoring and evaluation dashboards. Development organizations tracking disease burden across African countries can compare Nigerian epidemiological data against regional neighbors using consistent metrics from a single API source. The API responds with well-structured JSON objects using intuitive field naming. Developers can get a working disease data integration running in under an hour, making it an excellent choice for hackathons, academic projects, and rapid prototyping of health applications targeting Nigerian users and health system stakeholders.

Infermedica Symptom Checker API is an AI-powered clinical decision support platform that provides symptom assessment, triage recommendations, and medical condition identification through a conversational API. Built by Infermedica, a medical AI company whose technology has been validated against physician diagnoses, the API powers symptom checker experiences in telemedicine apps, digital health platforms, hospital patient portals, and health chatbots that need clinically reliable medical triage logic without building medical AI from scratch. The core interaction model of the Infermedica API is a dialogue: a patient initiates a symptom assessment by describing their chief complaint, and the API responds with follow-up questions that progressively narrow the set of probable conditions. This AI-driven interview collects relevant symptoms, risk factors, and medical history data through structured yes/no and multiple-choice questions derived from probabilistic clinical reasoning models trained on millions of clinical cases. The process mimics the triage interview a clinician performs but delivers it through a digital interface that can run 24 hours a day without clinical staff involvement. The triage output from Infermedica classifies the urgency of the patient's presented symptoms into categories — emergency (call emergency services immediately), consult soon (see a doctor within 24 hours), self-care (symptoms can be managed at home) — with structured rationale for the triage classification. For Nigerian telemedicine platforms and digital health services that need to prioritize patient consultations or direct patients to appropriate care levels, the triage API provides the clinical logic layer without requiring in-house medical AI development. Condition probability output from Infermedica ranks the most likely diagnoses consistent with the symptoms and risk factors collected during the interview, with probability scores and ICD-10 codes for each condition. This differential diagnosis output helps healthcare providers who review the pre-consultation triage data focus their clinical assessment on the most likely conditions rather than starting from scratch, improving consultation efficiency. For Nigerian telemedicine platforms — where a significant proportion of consultations involve triage questions that could be handled before the doctor connects — Infermedica's symptom checker API can function as a pre-consultation digital intake tool that collects symptom history, performs initial triage, and delivers structured data to the clinician before the video call begins. This workflow improvement increases the clinical value of each consultation and reduces the amount of basic history-taking the physician must do within the consultation time. Mental health symptom assessment is supported through specific Infermedica models covering anxiety, depression, and other common mental health presentations. Nigerian mental health platforms and employee wellbeing apps can use these models to provide structured mental health screening tools that identify individuals whose symptom patterns suggest they would benefit from professional support, directing them toward appropriate services. The Infermedica API is designed for enterprise integration with developer-accessible REST API endpoints, comprehensive documentation, and sandbox environment access for testing. Nigerian health tech developers can explore the API capabilities using test credentials without production data before building health-app integrations. Regulatory compliance considerations for the Nigerian health tech context — including FMOH and NHIA guidelines — apply to how symptom checker features are presented and what clinical claims are made about the tool's outputs.
