textCAPTCHA API

The service implements captcha to prevent bots and automated scripts from submitting forms and using other website resources, typically for the purpose of posting spam messages. Unlike services using distorted images, textCAPTCHA posts random, text-based questions, such as easy arithmetic problems or logic puzzles, which users must correctly solve to proceed. Bots unable to interpret the meaning of the text are prevented from continuing.

API methods support requests for questions and MD5 hashes of any permitted answers.

I'm Human API

The I'm Human API is "where humanity wins the fight against machines," according to elxsy.com, the provider of the service. I'm Human is a visual CAPTCHA service which responds with a word, a grid of up to 25 images and the grid numbers which correspond to the correct answers. Humans must select the images that match the words and your application compares the results to the correct answer from the I'm Human API.

Google OpenID API

The Google OpenID API lets third-party web sites and applications let visitors sign in using their Google user accounts. The OpenID standard allows users to nor have to set up separate login accounts for different web sites, and conversely, frees web site developers from the task of managing login information and security measures. OpenID achieves this goal by providing a framework in which users can establish an account with an OpenID provider, such as Google, and use that account to sign into any web site that accepts OpenIDs. This page describes how to enable a web site or application to accept a Google user account for federated login.

Google safe browsing API

Reminder: Safe Browsing version 1 API turning down December 1


In May Google announced that Google are ending support for the Safe Browsing protocol version 1 on December 1 in order to focus our resources on the new version 2 API and the lookup service. These new APIs provide simpler and more efficient access to the same data, and they use significantly less bandwidth. If you haven't yet migrated off of the version 1 API, Google encourage you to do so as soon as possible. Our earlier post contains links to documentation for the new protocol version and other resources to help you make the transition smoothly.

After December 1, Google will remove all data from the version 1 API list to ensure that any remaining clients do not have false positives in their database. After January 1, 2012, Google will turn off the version 1 service completely, and all requests will return a 404 error.

Thanks for your cooperation, and enjoy using the next generation of Safe Browsing.
