The data

Klarna data,
ready to work with.

Klarna search returns product matches with titles, categories and displayed prices. That first amount is useful for discovery, but it is not a checkout quote or every seller’s offer. Open a selected product and its offers when the merchant, currency and condition matter. The Beats Studio Pro result shown here came from a headphone query; its retailer count and rating were recorded with the same search response. Price history and comparison have separate operations, so a current-looking search card should not be read as a historical trend. Monocrawl returns these public shopping records as JSON for product research that keeps the source item attached.

Before you build

Klarna API questions,
answered.

Need to check a particular workflow?
Talk to us

Is a Klarna search price a checkout price?

No. It is the displayed amount in one recorded search response. Open offers and retain the seller, region, currency and collection time before comparing prices.

Does the retailer count show every available shop?

No. It is a source-reported count for that product at observation time. It can differ from the offers returned to a particular request.

What Klarna operations can I use?

The catalogue shows 18 currently available operations with their individual prices. Open an endpoint for its accepted inputs, returned fields and limitations.

How much does the Klarna API cost?

Start with 150 free credits. Paid subscriptions start at $29 per month for 10,000 credits, before applicable tax. Each operation has its own price. Check the endpoint reference for variable charges. Compare plans

How do I authenticate requests?

Use your Monocrawl API key in the x-api-key header. The endpoint reference lists any additional inputs needed for the operation. Authentication guide

What request limits apply?

Limits depend on your Monocrawl plan. The Free account ceiling is 600 requests per minute and 50 simultaneous requests. Endpoint capacity and Free daily protections also apply; these ceilings do not guarantee source throughput. Read the limits guide

What should I know about Klarna coverage?

Displayed search prices, instalment figures and retailer counts are dated source observations, not checkout quotes. Offers and history may cover different merchants, markets or time windows; keep that context with every amount.

Is Monocrawl affiliated with Klarna?
