Checked the JSON search API as the obvious incumbent option. It is closed to new customers and on a published sunset path, so it was not viable for a product that needs a multi-year commitment. Its low daily query ceiling and terms around reusing results would also have been awkward for a feature that stores what a user keeps. Eliminated early on availability alone.

- A product that cannot be newly provisioned and has an announced end date cannot anchor a paid dependency. The deprecation status was easier to learn from third-party write-ups than from the product pages themselves.
