Last Updated: June 4, 2018

The following terms and conditions (the “API Terms of Service”) govern your access to, and use, of our proprietary application programming interface, including our ‘REST API’ or ‘Websocket API’ (collectively, the “Bitfinex API”) and the related documentation, the current version of which is located https://docs.bitfinex.com/docs (the “Bitfinex API Documentation”), all of which are designed to facilitate your access to, and use of, our Services (as defined in the Terms of Service).

These API Terms of Service supplements, and forms part of, our standard terms of service, the current version of which is located at: https://www.bitfinex.com/legal/terms (“Terms of Service”). Accordingly, capitalized terms used, but not defined in these API Terms of Service, have the meanings set out in the Terms of Service.

    1. a) API Keys Required to Access the Bitfinex API. In order to use the Bitfinex API, you must first sign up for an account through the Site (as defined in the Terms of Service). Certain authenticated features and functionality available through the Bitfinex API require an authentication key. If you wish to access these features and functionality through the Bitfinex API, you must further generate one or more API keys (each, an “API Key”). You acknowledge that such API Keys are our confidential information and will not share your API Keys with any third party without our prior consent. In addition, we may revoke your API Keys any time without our consent.

    4. d) Open Source Libraries. From time to time, we may make available to you our libraries that assist you with the development of Applications, such as our Go, Node.js and Ruby libraries (such libraries, the “Bitfinex Open Source Libraries”).
