Why this works

Four APIs that cover the full agentic purchase journey.

Discovery + matching

Promo Discovery and Entity Mapping give agents verified offers across 75k merchants and a canonical product graph — structured data, not scraped guesses.

Checkout orchestration

Merchant Map provides CSS-selector templates per merchant so agents navigate checkout deterministically, cutting token cost by ~95% and lifting completion rates.

Downstream enrichment

The Offsite Context API adds top-of-funnel intent, geo, and SKU-level signals — feeding richer audiences into partner data products.

Kindred network: 75,000 merchants across 244 countries / territories, 16 languages, 65% outside Shopify.
