Canonical post wrappers retain reaction activity separately. Date bounds filter post publication within this window; unknown dates remain included. The source is not date-sorted and does not expose continuation or exhaustive totals. Optional urn validates the returned member but does not reduce source calls. Invalid inputs and all failures cost zero; a filtered empty window costs zero. An empty upstream dataset cannot establish a valid empty profile and fails uncharged. Finite trial capacity is bounded by a shared ten-run limit; sustained production funding is not configured. Pass a canonical public profile URL, for example `https://www.linkedin.com/in/satyanadella/`. The response contains at most **20 source-ranked activities**, not the member's full history. The source does not expose continuation, an exhaustive total or guaranteed date ordering; `complete` is false and `next_cursor` / `total` are null. Each item has a canonical `post`, null AI `computed` fields and a separate `activity` with the reacting member and reaction date. `since` and `until` filter **post publication**, not reaction time. Bounds apply only to this limited window; unknown dates are retained. An empty filtered result is free. Post activity IDs can differ from the public UGC URL ID. The adapter checks the source relationship and preserves both identifiers under `post.ext`. Hidden or missing counters remain null. A source identity mismatch rejects the entire response. An optional `urn` accepts an opaque `ACo...` member identifier or the `urn:li:fsd_profile:` / `urn:li:fs_miniProfile:` prefix. It must match the returned member. It does not skip a source lookup or reduce provider cost. Other filters, pages, universal cursors and AI enrichments are unsupported and return an uncharged error. Nonempty uncached responses cost **5 credits**. Cache, replay and all failures are free. An empty upstream dataset is not proof that a member has no activities and is rejected uncharged. Use a 60-second client timeout and `X-Max-Credits: 5`. These pinned Apify Actors run with limited permissions and a \$0.04 maximum each. They share a non-resetting ten-run verification ceiling within the existing free allowance. No subscription or top-up is enabled, and sustained funded availability remains unconfigured. ## OpenAPI ````yaml GET /linkedin/profile/reactions openapi: 3.1.0 info: title: SocialQuery API version: '2026-10-09' description: >- Documented requests for public-source records.
