Unified transcription endpoint that replaces the five v1 endpoints (vid2txt, aud2txt, videofile2txt, audiofile2txt, transcribe). Accepts URLs or multipart file uploads. Returns a request_id for status polling.
Source detection is automatic: pass a public video_url / audio_url, or upload a file via multipart form-data.
Prerequisite: Consult the Model Selection endpoint to identify a valid model slug and check supported languages.
OpenAI SDK users: This endpoint is also available via the OpenAI-compatible surface as POST /v1/audio/transcriptions at https://oai.deapi.ai/v1. Maximum file size per upload is 20 MB for audio and 50 MB for video, subject to a global 75 MB request body cap. See OpenAI Compatibility and Limits & Quotas.
