The Fitch Finance API simplifies access to archived securities data of the U.S. equities market. The digitized data that dates back to 1968 is stored in OHLCV format and summarizes the historical details of market performance of more than 20,000 stocks. The RESTful API is functionally designed to support cross-origin-resource sharing and use HTTP response codes to signal errors. It also sends requests in HTTP format and returns responses in JSON format. The Fitch Finance API is a full release that is well documented and appropriately backed by Java, C, ruby, and python languages.
