Do not treat a publicly accessible demo URL as permission to publish the game commercially. Obtain permission for your intended use or have counsel establish another defensible basis; this is not a claim that every link or embed automatically infringes copyright. The US Copyright Office explains that permission is not required for every use, but that securing it is often the clearest way to resolve uncertainty. (copyright.gov)

Studio terms illustrate the problem. Pragmatic Play’s public terms restrict use to non-commercial purposes and require express written consent for specified uses with other products or services. Play’n GO’s terms also reserve rights in website materials and restrict reproduction without consent. These are public website terms, not evidence of what either company might offer under a separate publisher agreement. (pragmaticplay.com)
Before using a discovered endpoint:
- Identify the game, studio and party supplying the URL.
- Ask whether it is a supported production endpoint or a preview link.
- Request confirmation of the permitted domains, audience and presentation.
- Check whether artwork, screenshots and descriptions have separate conditions.
- Record the permission document and its effective date alongside the game record.
If permission is unclear, keep the review page editorial-only while resolving it. Do not extract a different launch URL or remove supplier restrictions to make an uncertain integration work.
