If you wish to confirm that your application constitutes an acceptable use of the Yahoo! Address Book APIs or wish to inquire about rate limit increases, register your application with us.
YOU SHALL NOT:
(i) use the Yahoo! Address Book APIs in connection with or to promote any products, services, or materials that constitute, promote or are used primarily for the purpose of dealing in: spyware, adware, or other malicious programs or code, counterfeit goods, items subject to US embargo, hate materials (e.g. Nazi memorabilia), goods made from protected animal/plant species, recalled goods, hacking/surveillance/interception/descrambling equipment, cigarettes, illegal drugs and paraphernalia, unlicensed sale of prescription drugs and medical devices, pornography, prostitution, body parts and bodily fluids, stolen products and items used for theft, fireworks, explosives, and hazardous materials, government IDs, police items, unlicensed trade or dealing in stocks and securities, gambling items, professional services regulated by state licensing regimes, non-transferable items such as airline tickets or event tickets, non-packaged food items, weapons and accessories;
(iii) use the Yahoo! Address Book APIs to operate nuclear facilities, life support, or other mission critical application where human life or property may be at stake. You understand that the Yahoo! Address Book APIs are not designed for such purposes and that their failure in such cases could lead to death, personal injury, or severe property or environmental damage for which Yahoo! is not responsible;
(iv) sell, lease, or sublicense the Yahoo! Address Book APIs or access thereto without Yahoo!'s prior, express, written permission;
(v) use the Yahoo! Address Book APIs in a manner that exceeds reasonable request volume, constitutes excessive or abusive usage, or otherwise fails to comply or is inconsistent with any part of the Yahoo! Address Book API documentation located within http://developer.yahoo.com/addressbook/, as determined by Yahoo! in its sole discretion;
Browser Based Authentication. Yahoo! requires that You use Browser Based Authentication (“BBAuth’) as provided in this Section (1(j)) to gain access to Yahoo! user accounts.
(i) Yahoo! takes end user security and privacy very seriously, and You agree to give us all necessary assistance for the operation of Your Application in compliance with these TOU and any applicable laws.
(ii) Securing User Consent. You are solely responsible for securing clear, express consent from the user, granting You permission to access such user’s Yahoo! account using the BBAuth API, including if applicable, retrieving user-specific information, or writing information to such user’s account. You will strictly comply with the scope of express consent they granted You when accessing such user’s Yahoo! account. Additional details regarding BBAuth can be found here: http://developer.yahoo.com/auth.
(iii) Contact and Cooperation. You (or the name of the contact You gave to Yahoo! when You applied for Your application ID for review if it's not You) must be reachable at all times for security questions or concerns. You can change this name or contact by signing up for a new application ID, and providing the correct contact information and using the new application ID instead. (http://developer.yahoo.com/wsregapp/)
(iv) Virus Precautions. All materials, including software and documents, that You provide to Yahoo!, must be checked with Internet industry standard up-to-date antivirus and anti-worm software, and determined to be virus-free and worm-free. Any data provided to Yahoo! must not contain harmful scripts or code.
(v) Industry Standards. Your networks, operating system and software of its web server(s), routers, databases, and computer systems must be properly configured to Internet industry standards, as required to securely operate Your Application. If You do not completely control any aspect of the System, You will use all control or influence that You have over such Systems and/or selection of Systems, and You will not architect or select Systems in a manner to avoid the foregoing obligation. An example of an unacceptable server is one that operates as open proxy. An example of architecting in an unacceptable manner would be if You select a server operated by a vendor with substandard security practices, so that You could contend that You do not control such server, in order to avoid having to select an acceptable server.
(vi) Reporting. You must promptly report any security deficiencies in or intrusions to Your Systems that You discover to Yahoo! in writing via email to firstname.lastname@example.org . You will work with Yahoo! to immediately correct any security deficiency, and will disconnect immediately any intrusions or intruder. In the event of any such security deficiency or intrusion, You will make no public statements (i.e. press, blogs, bulletin boards, etc.) without prior written and express permission from Yahoo! in each instance.
(vii) Control Access to Systems. To the extent You have control or influence over the Systems, You will log (in a time and date-stamped fashion) all instances of access to the Systems. You will encrypt the password and username files for the Systems that store or process any Yahoo! user data that You are permitted by Yahoo! to access. Passwords must be unique, unintuitive, and changed often. You will minimize access to and use of the passwords. Wherever possible, commands which require additional privileges should be securely logged (with time and date) to enable a complete audit trail of activities. When an individual terminates his or her employment with You, his or her passwords and access password facilities must be terminated immediately.
(viii) Security Reviews. Yahoo! will have the right, at its own expense, to review, or to have an independent third party that is not Your competitor, to inspect and review Your compliance with these security provisions. You will (at Your own expense) correct any security flaws detected by such a review as soon as possible. You will then promptly certify to Yahoo! in writing that the security flaw has been corrected, along with a description of the corrective action(s) taken. Yahoo! will give You 48 hours notice before conducting such a review, and may conduct no more than four reviews annually. Any such review will be conducted during regular business hours in such a manner as not to interfere with normal business activities. If a review reveals a material breach of any of these security provisions, You will reimburse Yahoo! for the reasonable costs of the review.

If you are a California resident, you waive your rights under California Civil Code § 1542, which states, "A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor." You understand that any fact relating to any matter covered by this release may be found to be other than now believed to be true and you accept and assume the risk of such possible differences in fact. In addition, you expressly waive and relinquish any and all rights and benefits which you may have under any other state or federal statute or common law principle of similar effect, to the fullest extent permitted by law.
Hold Harmless and Indemnity.
