Monetization infrastructureyou can program.
Run auctions, ranking systems, and sponsored listings with full control over delivery logic. Like Stripe for marketplace monetization — not another ad server.
Developer Experience
Designed for engineering teams embedding monetization into product experiences.
Clean APIs, predictable responses, flexible schemas. Run your first auction in minutes, not months. Every decision is traceable — your team stays in control.
import { Topsort } from '@topsort/sdk';
const client = new Topsort({ apiKey: 'ts_live_...' });
// Run an auction in <10ms
const auction = await client.auctions.run({
type: 'listings',
slots: 3,
products: catalog,
context: { category: 'electronics', query },
rules: {
pacing: 'smooth',
eligibility: (bid) => bid.budget > 0,
ranking: 'relevance_weighted',
}
});
// Every decision is inspectable
console.log(auction.decisions);
// → [{ productId, rank, bidPrice, winPrice, reason }]Why T-Zero
Product infrastructure, not ad ops software.
Programmable
Define your own auction mechanics, ranking logic, pacing, campaign eligibility, and placement rules. The platform executes at scale.
Transparent
Every auction and ranking decision can be inspected and understood. No black boxes. Engineering teams get full observability.
Flexible
Integrate monetization directly into your product experiences. APIs, extensibility, flexible schema, predictable responses.
Future-proof
Start with full control. Add automation when you're ready. A natural path from rules to ML optimization — no rebuild required.
Honest Comparison
Legacy ad servers vs. programmable infrastructure.
Most ad servers were built a decade ago for display advertising. T-Zero is built for modern commerce.
Platform Architecture
Start with control.
Evolve toward automation.
T-Zero is the foundation layer. As your retail media program matures, unlock optimization and AI — without rebuilding. Legacy providers only offer layer one. We offer the entire progression.
How It Works
Three steps to programmable monetization.
Install the SDK
npm install @topsort/sdk — TypeScript-first, fully typed, zero config. Connect your product catalog and define placement surfaces.
Configure your rules
Define auction mechanics, ranking logic, pacing strategies, and eligibility rules. Your business logic, executed at infrastructure scale.
Go live & inspect
Serve auctions in <10ms. Every decision is traceable. Monitor, iterate, and evolve — add ML optimization when you're ready.
A programmable monetization engine for marketplaces that want full control.
Start with control. Evolve toward automation. No rebuild required.
Start building in
minutes, not months.
