Klarna Agentic Product Protocol API
Product search and merchant offer data
Supplies normalized product search results and merchant offers for shopping agents.
THE QUESTION IT ADDRESSES
Where can an agent obtain comparable product and offer data?
A concise reading of published information. The explanatory grouping below is editorial, not an implementation test.
A simplified mechanism
- Use the current Product Search v2 endpoint to find products.
- Retrieve offers with pricing, stock and shipping details through Product Listings.
What it does not establish
Partner approval and an access token are required. Search v1 is deprecated while Product Listings remains v1. Product discovery does not execute a payment or approve credit.
Where it fits
An operated catalog API despite the product’s Protocol name; keep it distinct from Klarna payment and installment products.
