An End User License Agreement (EULA) is the license that governs how people may install and use your software: the rights you grant and the restrictions and disclaimers attached to them. For an API Service, getting it right matters: An API service processes API keys, request payloads, and usage logs on behalf of your customers, so your terms and privacy policy need to cover both your own data handling and what you do with the data customers send through your API. This free EULA generator asks a few questions about your API Service and assembles a tailored document you can copy or download in seconds.
Why your API Service needs a EULA
A EULA sets the terms of a software license rather than a service, limits your liability, and lets you prohibit misuse such as reverse-engineering, resale, or redistribution.
An API service processes API keys, request payloads, and usage logs on behalf of your customers, so your terms and privacy policy need to cover both your own data handling and what you do with the data customers send through your API.
What an API Service EULA should cover
A good EULA for an API Service is specific to how your product works. At a minimum, address:
- What request data, payloads, and logs you store, and for how long
- API keys, authentication, and rate limits
- Whether you process data as a controller or as a processor for customers
- The scope of the license you grant (personal, non-exclusive, revocable)
- Restrictions such as no reverse-engineering, resale, or redistribution
- Ownership of intellectual property and any third-party components
- A warranty disclaimer, liability limits, and termination terms
How this generator works
PolicySmith builds your EULA entirely in your browser — nothing you type is sent to a server. Answer the questions above about analytics, payments, AI features, and the regions your users live in, and the document updates to match. Export it as HTML or Markdown, paste it into your API Service, and link to it from your store listing or footer.
Frequently asked questions
How is an API service different from a regular SaaS privacy policy?
An API service often processes data that belongs to its customers rather than to your own users. Your policy should distinguish between data about your customers (their account, billing) and data your customers send through the API on behalf of their own users.
EULA or terms of service — which do I need?
A EULA licenses installed software; terms of service govern an online service. Desktop, mobile, and downloadable apps typically use a EULA, while web and SaaS products use terms of service — some use both.
Is a click-through EULA enforceable?
Generally yes, when users must affirmatively accept it (a clickwrap "I agree") before using the software. A EULA with no acceptance step is weaker. Have a lawyer review high-stakes terms.
