Zzize REST API

One endpoint. Every margin, priced.

Send a listing image and a target market. Zzize returns a condition grade, authenticity signal, comparable sold prices, and a fully landed arbitrage margin — as clean JSON you can pipe straight into your stack.

  • Sub-second responses with context-cached vision inference
  • Landed cost per target market: FX, tariffs, and shipping
  • Real-time webhooks when spreads cross your threshold
