LinkedIn Post Transcript API
LinkedIn post text as a transcript — paragraph segments, timingSource none.
Paste a LinkedIn post/activity URL and get the public post body as structured text: transcript, wordCount, author, publishedAt, and transcriptSegments split on blank-line paragraphs (including NBSP gaps). timingSource is always "none" today (on every path) — no caption track or speech-to-text. When timingSource is "none", segment start/duration/timestamp are omitted (returned only when timingSource is "captions"). Each segment has index, wordCount, charStart/charEnd into transcript. estimatedReadSeconds is a single top-level 200 wpm estimate — never inside duration. There is no segments count key and no language key — LinkedIn does not expose a speech language, and we do not guess from the body. timings{nativeMs,totalMs} time the fetch. Read from LinkedIn's logged-out post page only: a deleted post is 404; LinkedIn's sign-in page or a failed fetch is 502 UPSTREAM_UNAVAILABLE, retryable, 0 credits. Flat 1 credit.
