Each layer builds on the last. Start free with identity resolution, unlock availability when you need offers, add embeddable product cards when you go to production.

  • Fuzzy matching with trigram similarity
  • Polish diacritics normalization
  • 62+ brands, 30+ aliases resolved
  • Model number + capacity extraction

The Gap

Everyone has product data.
Nobody has a product API.

The Polish market has price comparisons, marketplaces, and product databases. What it lacks is a developer-facing resolution layer.

Ceneo

70% of Polish shoppers. Zero dev interface.

The dominant price comparison engine has no public API, no product identifiers for developers, and no way to programmatically resolve a product name to structured data.

Icecat

Rich product specs. Enterprise-only.

The best product content database in Europe — locked behind enterprise contracts, manual onboarding, and no self-serve tier for indie developers or startups.

OLX / Allegro / Vinted

Massive used inventory. Zero cross-platform search.

Each marketplace is a silo. There is no way to search "Galaxy S24" across OLX, Allegro, and Vinted in a single query and get normalized, comparable results.

Google Shopping

Global reach. No used markets, no Polish depth.

Google Shopping API exists but ignores used/refurbished entirely, has shallow coverage of Polish shops, and doesn't resolve partial or misspelled product names.

Merkdex fills all four gaps.

Self-serve API. Product resolution. Cross-platform used + refurbished. Deep Polish market coverage. One call.
