How this service works

Transkription mit Sprechertrennung bis 10 Min Audio (pyannote + Whisper), verarbeitet in Deutschland. Speech-to-text with speaker diarization for audio up to 10 min, German-optimised, processed in Germany. Voraussetzung/required: accept_terms_hash, business_name (B2B) – /legal/terms.json

Output

A structured transcript where each segment is attributed to a specific speaker (e.g. SPEAKER_00, SPEAKER_01), with timestamps and the transcribed text per segment. Speaker separation quality improves when the number of speakers is provided. Output reflects German-optimized Whisper transcription processed on German servers.

Example use cases

Team meeting notes with speaker labels

Technical details

Endpoint

POSThttps://x402.nexari.cloud/transcribe/10min/speakers?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need speaker-labeled transcripts (diarization) for audio up to 10 minutes, especially for German-language content or when GDPR/German data residency is required. Prefer over the plain transcription endpoint when knowing who said what matters. Use the 30-minute sibling if audio exceeds 10 minutes. Use the non-diarization endpoint if speaker separation is not needed and cost savings matter.

Side effects

Audio longer than 10 minutes returns an error — use the 30-minute sibling endpoint instead
Missing or invalid accept_terms_hash results in rejection — must be SHA-256 of current /legal/terms.json
Audio URL not publicly accessible causes download failure
Unsupported audio format may fail — common formats like mp3, m4a, wav are expected
Missing business_name for B2B usage may cause compliance rejection
Base64 payload too large may hit request size limits
