What is seedance-2-api?

This repository is a set of runnable examples and a price comparison for running ByteDance's Seedance 2.0 video generation model through a service called useapi.net. A single useapi.net account can drive Seedance 2.0 through four different underlying platforms, PixVerse, Runway, Dreamina, and MiniMax, each with its own pricing and strengths, and the repository documents which route is actually cheapest based on prices the author verified in July 2026. A small command line calculator reproduces the pricing comparison for any resolution or clip duration without needing an account at all. According to the README's own figures, generating a five second 1080p clip through useapi.net's PixVerse route costs about $1.20, cheaper than going through a reseller called Segmind, cheaper than ByteDance's own official pricing, and much cheaper than going through Replicate or fal.ai directly. Beyond the calculator, a compare example sends the same prompt to all four Seedance routes at once, waits for each to finish, downloads the resulting clips, and prints the cost and generation time for each one side by side. Running it requires Node.js and a useapi.net API token, plus connecting accounts on each of the four underlying platforms, which the README notes are all covered by a single monthly useapi.net subscription. A lower resolution setting is suggested while testing changes, since it works across every route and on some account types does not spend any credits. The README describes useapi.net itself as an experimental REST API that operates through a person's own existing accounts on these AI video and image platforms, letting them pay those platforms' regular consumer prices rather than separate metered developer API rates, which is the reason this approach ends up cheaper. The README warns that the listed prices shift on a roughly weekly basis and should be reverified before anyone relies on them for a real decision.
