We publish a substitute list only where a record says what kind of product it is. AbstractAPI's does not yet, so this page names none. The API Development category lists every offer we track alongside it.
Current AbstractAPI Situation
Risk Level:source unconfirmed
Why: When we last read the page we cite for AbstractAPI, on 2026-11-01, we found the same terms as an earlier read we had declined to record. We are not publishing a stability judgement for it until that is fixed.
