We've previously covered 3 free to geolocate any user. Today there's another option, with Quova offering its service for free for the first time. The simple API provides extensive geographic information with only a user's IP address (like 18.104.22.168) as input. The service was announced, along with a developer portal, at the Business of APIs conference in San Francisco.
BlockAvenue, location-based analytics company, has announced the release of its first BlockAvenue API. The API gives developers access to BlockAvenue's data (e.g. BlockScores, block reviews, neighborhood reviews, counts, etc.). BlockAvenue provides geolocation data on most neighborhoods across the US, often down to the block level. Its database grows everyday and BlockAvenue expects the API to push BlockAvenue towards its ultimate goal.
