This document provides an overview and case studies of using the Yahoo Query Language (YQL), Flickr API, and Instagram API. It discusses obtaining API keys, usage limits, and makes API calls to retrieve stock quotes, city location IDs, photos from specific cities and areas, photo metadata, and conduct searches. Examples demonstrate retrieving JSON/XML data on stock prices, city WOEIDs, photos matching queries, and photo URLs. The document also references documentation on registering applications, pricing, Flickr app registration, and API endpoints for each service.
