The National Cancer Institute has developed an API that streamlines connecting doctors and patients to information regarding cancer clinical trials. The API pulls data from the Clinical Trials Reporting Program database, which currently includes information on around 5,000 clinical trials.
With 25 million business listings over nine countries, open data company Factual has taken a first step toward creating a place database to which anyone can contribute. With location-based applications now more popular than ever, the data is extremely valuable to developers. Factual is providing it via its API, currently for free.
