Side-by-side comparison

Pick 2–4 products to compare.

Pass canonical product IDs as a comma-separated ids query parameter:

/compare?ids=<uuid1>,<uuid2>[,uuid3[,uuid4]]

Get UUIDs from /v1/products/<slug> on the engine, or from the id field on any search result. The engine returns 422 for fewer than 2 or more than 4.
