How this service works
HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a structured transcript package containing the extracted text, timing/segment data, per-segment confidence scores, and detected or specified language metadata from the audio or video source.
Example use cases
Meeting recording to text notes
“Transcribe this recorded team meeting for me — the file is at https://storage.example.com/meeting-2024-06-10.mp3, it runs about 45 minutes but I only need the first 30, and the language is English. Filter out anything below 75% confidence.”
Multilingual podcast transcript
“I have a multilingual podcast file encoded in base64 — can you transcribe it? It's about 15 minutes long and the speakers switch between languages, so use 'multi' for the language setting and keep the confidence threshold at 0.7.”
Foreign-language interview transcription
“Please transcribe this German interview recording from https://archive.mysite.de/interview-schmidt.wav — it's around 12 minutes long and I want high-confidence results only, so set the confidence threshold to 0.85.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/transcript-package?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a full transcript package from an audio or video file, especially with multilingual support, confidence filtering, and structured segment output. It is well-suited for podcast episodes, recorded meetings, interviews, and news media up to 30 minutes. Prefer it over generic STT APIs when you need built-in confidence thresholding and can supply the file by URL or base64. Not suited for real-time streaming transcription or files longer than 30 minutes.
Side effects
- URL not reachable or returns non-media content — network or 404 error
- Base64 content too large (exceeds ~12 MB limit) — schema validation error
- duration_minutes exceeds 30 — rejected by schema
- Unsupported audio/video codec or format — transcription failure
- Low-confidence audio (heavy noise, unclear speech) may produce sparse or empty transcript if threshold is high
- Language mismatch between specified language and actual content — degraded accuracy
