In this part of my series on my AJAX application, I'm discussing the impact of external APIs. My use of APIs has made me realize how much more API access I want! I'd love to see broader API availability from feed/blog companies for statistics, retail companies for catalogs, news corporations for news feeds, and search companies for both results and more interesting APIs (like Yahoo's). Essentially, I want a central directory of companies offering these services, recognizing that I'm a consumer of their data. I'm also realizing how many APIs (REST and SOAP) are out there that I could leverage. I envision adding more dynamism to my apps, like analyzing blog post keywords to see their popularity, potential ad revenue, and related keywords. I could then cross-reference this with other sources to give viewers more feedback, such as related blog importance, link counts, and other connections. I could even offer localized product information, best buy deals, or second-hand options based on keywords. This isn't revolutionary, but I need help finding lists of companies that offer web APIs and useful RSS feeds. Readers, please share your knowledge!
