# terms of service
last updated 24 august 2026
AD SLOT is a marketplace where the owner of an X account can list placements on their own profile — cover image, profile picture, display name, bio and pinned post — and let buyers bid on them.
You sign in with X. By signing in you confirm you control that account and that you are allowed to sell placements on it. One page per X account.
Sellers set the floor price, the auction length and how long the placement is held. Sellers are responsible for actually applying the winning placement to their profile for the agreed period, and for keeping it there.
Sellers may refuse any bid or creative for any reason. Buyers must have the rights to whatever they supply. Illegal content, impersonation, malware and scams are not allowed anywhere on AD SLOT.
AD SLOT is free while in early access. Payments, holds and fees will be introduced with clear notice before they apply to any listing.
AD SLOT is not affiliated with, endorsed by, or sponsored by X Corp. Your use of X remains subject to X's own terms.
These terms can change as the product grows. Continued use means you accept the current version. Questions go to hello@adslot.me.
