As people have been reporting on this group since yesterday (24 January 2014), the Local Search API has stopped functioning. Requests to the service endpoint are now being met with a 403 message indicating suspected TOS violations and abuse. Although I have seen no official announcement from anyone at Google, the reality is that this is not at all unexpected.
In short, I do not anticipate that the Local Search API will return. And I fully expect that the Web and other services formerly included in the AJAX Search API family will be shut down over the next few months as well.
So what alternative services are available? The answer to that question, of course, depends on what you're trying to accomplish. Unfortunately, because the (AJAX) Search APIs were something of a one-stop shop for a very wide spectrum of functionality, there is no one great answer. Therefore, I have endeavored to compile a list of what are probably the best alternatives depending on a few of what I consider the most common use case scenarios. These are provided in no particular order, and I will leave it to the developer to read the documentation and conduct testing to determine which is the best solution for any particular application.
Basic Web Search
Local business search
Geocoding (i.e., Local Search)
News Search
Image Search
Video Search
Blog Search
I have not found anything truly comparable.
I hope this helps those who are finding their applications suddenly dark! Blessings, and happy coding!
