You're looking at a URL that's part of Amazon's video infrastructure. The domain amazonvideo.com is unquestionably owned by Amazon, a massive and trusted company. The long subdomain name suggests this is a backend API endpoint, likely used for internal routing or load balancing. It's not a website you're supposed to visit directly. The 404 error confirms that: there's no page to interact with, no product to buy, no form to fill out. If you stumbled across this link, treat it as a dead end rather than a scam. The security setup is solid for an API, though the acceptance of older TLS versions is a minor technical concern. For anyone asking 'is threeplr-a3vn4e5f7bbc7s-0.na-f.api.amazonvideo.com a scam?', the answer is no. It's simply an Amazon endpoint that doesn't serve content. There's nothing to worry about, but also nothing to use.
