How this service works
HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns JSON containing speaker cue crosswalk data: timestamped boundaries for each speaker turn where the literal keyword was found, padded cue clip start/end points, and FFmpeg filter expressions ready for use in media pipeline processing.
Example use cases
Podcast episode keyword cue extraction
“I have a timestamped podcast transcript and I need cue markers for every speaker turn where the word 'announcement' appears literally — give me padded clip boundaries and FFmpeg expressions so I can cut those segments.”
Broadcast media speaker turn alignment
“Take my timestamped broadcast source and find all speaker turns containing the literal phrase 'loading dock' — return the crosswalk cue data with padding so my editor can jump straight to those moments.”
Training data clip generation from interview
“From my interview transcript, locate every instance where a speaker literally says 'procurement' and produce padded cue clips with FFmpeg filter expressions so I can export those segments as training samples.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/speaker-cue-crosswalk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise, literal-keyword-based speaker cue extraction from timestamped media sources and require FFmpeg-compatible output. It is purpose-built for media pipeline workflows where semantic search is explicitly not wanted — only exact vocabulary matches. Prefer this over generic transcript search tools when you need crosswalk-formatted cue data with padding for direct use in editing or encoding workflows.
Side effects
- Keyword not found in source — returns empty results or 404-style empty match response
- Source transcript not recognized or malformed — returns parsing error
- Literal match fails due to capitalization or punctuation differences — no results returned
- Payment not confirmed via x402 — request rejected before processing
- Source reference invalid or expired — returns source lookup error
