Technical details

Endpoint

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

When to prefer

Choose this endpoint when you need GDPR-compliant German-language speech-to-text processing hosted within Germany, for audio files under 10 minutes. It is ideal when data residency in Germany is required, when the audio is primarily in German (though other languages and auto-detection are supported), and when you want a flat per-call price of $0.10 USDC. Prefer the per-minute billing sibling endpoint for files between 10 and 50 minutes, or the speaker-diarisation endpoint when you need speaker separation.

Audio URL is not publicly accessible or returns an error
Base64-encoded audio is malformed or too large
