   1. API Key: If Licensee is provided a unique identifier to authenticate the API (“API Key”), you will not disclose or provide the API Key to anyone else other than to the employees, contractors, and agents authorized by Licensee to use the API for its organization (“Authorized Users”). If you would like to use the API for any other purpose than as expressly permitted herein, please submit a request using the contact form at https://www.semanticscholar.org/product/api.
   2. Third-Party Products: All Third-Party Products are separately governed by the third party’s terms and conditions (“Third Party Terms”). Licensee is solely responsible for complying with Third Party Terms and verifying that use of the API with any Third-Party Products does not violate or conflict with the Third Party Terms or Licensee’s obligations herein. AI2 will have no liability for any Third-Party Products and will not be responsible for addressing any technical or other issues arising from Licensee’s use of any Third-Party Products. 
2. S2 Data. Licensee’s use of S2 Data accessed via the API are separately governed by the licenses that accompany such S2 Data, such as CC BY-NC or ODC-BY (“S2 Data Licenses”). Further, S2 Data includes third party content and materials, such as open access works from publicly available sources, works under a public use license (e.g., Creative Commons), and works licensed by AI2 from others (collectively, “Third Party Content”). In addition to the S2 Data Licenses, any underlying Third Party Content may be subject to separate license terms by the respective third party owner. Licensee agrees to use S2 Data in compliance with the S2 Data Licenses and the licenses that govern any Third Party Content. 

3. Licensee Data. AI2 will use the data and information that Licensee provides and transmits to call or use the API (“Licensee Data”) for the purpose of providing and improving the API, S2 Data, and S2. Licensee will own its Licensee Data.

AI2 may monitor Licensee's use of the API, and compile Usage Data in an aggregate and anonymized manner, such as for statistical and performance information related to the provision and operation of the API (“Aggregated Statistics”).

Subject to the foregoing, AI2 hereby grants to Licensee a limited, non-exclusive, non-transferable, non-sublicensable and terminable license to use the S2 Marks solely on public displays of S2 Data via Licensee’s use of the API. Licensee will comply with any other written instructions provided by AI2 and will promptly correct or take down any use of S2 Marks upon AI2’s request. All goodwill arising from Licensee’s use of S2 Marks will inure solely to AI2’s benefit.

Any feature or functionality of the API is subject to change, and AI2 may add, remove, change, suspend, discontinue, or make any updates, modifications, enhancements, bug fixes, patches, or other error corrections to the API in its sole discretion.

   1. Rate Limits. You will not attempt to exceed or circumvent limitations on access, calls, and use of the API ("Rate Limits").

   2. Suspension. AI2 may monitor your use of the API to improve the service and to ensure your compliance with this Agreement. AI2 may limit, disable, or suspend Licensee's and any Authorized User's access or use of the API if AI2 reasonably believes Licensee or any Authorized User has breached any provision of this Agreement. In addition, AI2 may take any action necessary to investigate, mitigate or address any suspected or actual security threats, fraud, illegal activities, and excessive bandwidth usage, in which AI2 may throttle use until consumption is reduced.  AI2 will use commercially reasonable efforts to provide notice of any suspension and resume access as soon as the cause of the suspension event has been cured.
