To see the frames where a phrase is spoken, call Sume's hypit tile verb with around: {phrase, occurrence, padding} and a transcript_job_id. The phrase is resolved on the word-timed transcript, and you get pages of exact frames around that moment, each cell labeled with its time and the words spoken then.

This surface is flag-gated: it is listed where the matching environment flag allows them (development auto-on, production opt-in), so check tools_list or the OpenAPI before you build on one.

What is a tile?

hypit.tile/1 is a set of pages of exact frames. Each cell is labeled HH:MM:SS.mmm and, with transcript_job_id, the words being spoken at that instant with spans and context. Pages are sized so each cell survives the agent host's 1080 px inline downscale, so a 480 px portrait cell stays 480 px with two per page. Pass cell and columns to trade size for count. Tile is unbilled.

How do I choose which frames?

Pick exactly one style of selection.

Sample selection on hypit tile (Sume docs, read 2026-10-02)
SelectorUse
start/end with every or framesEven sampling (default about 1.5 per second, at least 4, at most 9)
at[]Explicit instants
around {phrase, occurrence, padding}A moment resolved from the transcript
ranges[]Several stretches in one call
layout: framesOne native-size labeled picture per instant

What does a request look like?

Transcribe first, then pass the transcript job id.

curl -X POST https://api.sume.com/v1/hypit-understand/tile \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: hypit-tile-001" \
  -d '{"understanding_id":"<probe job id>",
       "transcript_job_id":"<transcribe job id>",
       "around":{"phrase":"link in bio","occurrence":1,"padding":2}}'

When is this better than sampling every second?

Phrase lookup is the shortcut when you know what was said but not when. A hook line, a price mention or a call to action each have a moment you want to see: what is on screen as the words land, whether text appears with them, and where the cut falls relative to the sentence.

Sampling every second answers a different question, what the video looks like overall. For that, tile with every or frames, or reference ingest, which already gives one keyframe per shot. The two compose: ingest for the shot list, then a phrase tile for a close read of the hook.

What goes wrong?

hypit_tile_transcript_required is around without transcript_job_id. hypit_transcript_not_found means that job is not a completed transcribe of this understanding in this workspace. hypit_tile_too_many_cells fires when selectors resolve to more than 96 cells; raise every, lower frames or split ranges[]. If the phrase is misheard by the ASR it will not resolve, so check low-score words on the transcript first.
