## klarna/compare

`GET /v1/klarna/compare`

Two products side by side: prices, ratings and the category's attribute groups.

*Klarna product comparison*

| Parameter | Required | Description |
| --- | --- | --- |
| `id` | yes | First product id — e.g. `3331931645` |
| `id2` | yes | Second product id — e.g. `3216399795` |
| `region` | no | Catalogue region — e.g. `usa` |
| `dry_run` | no | Read a zero-credit estimate without fetching sources, running AI, or reserving credits. Cache status is a snapshot, not a guarantee at execution. — e.g. `1` |

**Cost:** 3 credits at list price per successful uncached response; variable-cost operations may quote or settle a different charge. Confirmed uncharged or refunded failures report zero. Pending reconciliation can report credits_used:null; retain request_id and the original idempotency key.
