EnClout Yahoo Finance is an API that assists developers to decode Yahoo stock symbols into JSON and XML protocols. In the site, the user can test the service to observe important data such as last date trade and the low and high values of the past 52 weeks. Developers working in the finance sector can benefit from this API, because long lists of stocks can display investment information in a simplified format. The results vary according to data availability. HTML, JSON, XML and TXT formats are available, along with a contact page. For better results, developers must sign up to get an API key.
