Short answer: No. There is currently no charge to use the core Web4 products.
The one exception: If you use AI features through GLACIER that call official, metered AI APIs, or if you choose to connect paid third-party APIs to something you've built, those usage costs are billed by the API provider — not by LINKSPREED as a platform fee.
Why it's structured this way: LINKSPREED is self-funded with no outside investors, so there's no pressure to introduce platform take-rates or subscription fees to hit a return target. Commitments like free core tools are structural choices rather than temporary promotions.
