ACP feed and checkout readiness
Whether a store targeting ChatGPT checkout ships the ACP feed with correct eligibility flags and the return fields checkout-eligible items require.
Per-platform status
Where a platform documents relevant behavior, its status and source are shown. Undocumented platforms show "unknown" - honest unknowns, never invented.

How to act on this
If you target ChatGPT checkout, enroll in OpenAI's merchant program, set is_eligible_search on products to surface, and set is_eligible_checkout only on rows that also carry return_policy and the required return-window fields.
