TL;DR

LinkedIn post text as a transcript — paragraph segments, timingSource none. Flat 1 credit. The LinkedIn Post Transcript API (LinkedIn) is a single authenticated GET request to /v1/linkedin/post-transcript that responds with clean JSON and costs 1 credit. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the LinkedIn Post Transcript API?

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 (native and Apify) — no caption track or Whisper. 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. Flat 1 credit.

What you get

Full transcript text with start/end timestamps when available
Auto-detected language and segment count
AI audio transcription fallback when no captions exist
Clean JSON ready for search, subtitles, or AI pipelines

Top-level fields

platformPlatform identifier for this response (matches the endpoint's platform).
urlCanonical URL of the item.
transcriptFull LinkedIn post body text (not speech-to-text from a video).
wordCountWord count of the full transcript (emoji-only tokens count as 0; URLs count as 1).
segmentsNumber of paragraph segments in transcriptSegments.
publishedAtISO-8601 when guest HTML/JSON-LD exposes it (including VideoObject datePublished on ugcPost URLs).
timingSourceAlways "none" on this endpoint today (native and Apify). "captions" is reserved for future cue support — do not branch on it; nothing emits it yet.
estimatedReadSecondsWhole-transcript reading-time estimate at 200 wpm. Not per-segment duration.
languageAlways null today — LinkedIn text posts have no speech language. Present so clients share a schema with Whisper transcript endpoints.
