Your message and link in the rotating banner on the homepage, the screener, APEX City and the docs — and on the ad boat that sails the river in the 3D city. Pay by card or in XNT — one payment, nothing renews.
Card payments are handled by Stripe on their own page — card details never touch this server. Minimum $3, because card fees would otherwise eat most of a smaller payment. Prefer crypto? The XNT route is in the details above, and has no minimum.
1. GET /api/sponsor/pricing — live rate + demand multiplier
2. Send the XNT to HYiepS7mNCVVKoaDmZLQ6rNtMWHTQqKheM1NLGn1x8kJ (X1), keep the signature
3. POST /api/sponsor/purchase-xnt
{ wallet, message, impressions, payment_tx, link_url? }
Non-custodial: you build and sign your own transaction. We never ask for a private key, and there is nothing to connect.
POST /api/sponsor/checkout
{ message, impressions, link_url? } → { url } # open it, pay, done
This slot has never been sold. The traffic is small and we would rather tell you that than imply a reach we cannot prove. Live counts for tokens, pools and traders are on the screener; judge the audience yourself before spending anything.
