Endpoints Presigned Upload-URL anfordern Erster Schritt für jede Verarbeitung: holt eine signierte Upload-URL plus den `file_key`, den die anderen Endpoints später referenzieren.
Parameters Name Type Description filename required string Original-Dateiname inkl. Endung. size required number Dateigrösse in Bytes. content_type string MIME-Typ (z.B. video/mp4).
Examples
cURL
curl -X DELETE "https://loadsh.it/api/user/api-keys/key_123" \
-H "Authorization: Bearer lsh_live_xxxx"
JavaScript
const response = await fetch(
'https://loadsh.it/api/user/api-keys/key_123',
{
method: 'DELETE',
headers: { 'Authorization': 'Bearer lsh_live_xxxx' }
}
);
const data = await response.json(); Response {
"success": true,
"upload_url": "https://...",
"file_key": "inputs/1/abc.mp4"
} Convert file Converts a file to another format. Two paths: EITHER `jobId` from the /api/upload multipart flow (frontend), OR `file_key` from /api/nodrift/upload/presign (programmatic API use — recommended). Response contains `job_id` for polling via /api/nodrift/jobs/<id>. No container creation needed — nodrift.ch manages the GPU pool serverlessly.
Parameters Name Type Description jobId required string Job ID from /api/upload (frontend) OR file_key from /api/nodrift/upload/presign (API). targetFormat required string Target format (e.g. "mp4", "pdf", "png"). processing_mode string "auto" | "force_cpu" | "force_gpu" — with file_key path, routing is automatic.
Examples

body: formData
}
);
const data = await response.json(); Response {
"success": true,
"job_id": "job_abc123",
"status": "processing"

} Audio/Video transcription Transcribes audio/video via Whisper through the nodrift /jobs/dispatch flow (Spec 2026-05). Expects file_key from the presign upload. Returns job_id; client polls /api/nodrift/jobs/<id> until status=completed — that contains transcript, language, srt_url and vtt_url. No container creation needed anymore.
Parameters Name Type Description file_key required string R2 file_key from /api/nodrift/upload/presign. language required string ISO-639-1 code (de, en, fr, …). Leave empty for auto-detect. output_format string "text" (default), "timestamps", "srt", "vtt".

} Dispatch AI/Boost tool Universal dispatch for all 30+ AI Boost tools (bg-remove, upscale, voice-isolate, document-scan, chat-pdf, slides-generate, video-dub, …). task_type picks the tool, ai_options are tool-specific (see /api/nodrift/capabilities for the full list).
Parameters Name Type Description service required string Always "ai" for Boost tools. task_type required string Tool slug, e.g. "bg-remove", "subtitle-generate", "chat-pdf". List via /api/nodrift/capabilities. file_key string R2 file_key from the presign step. Optional for slides-generate (topic-only). ai_options object Tool-specific object. See nodrift spec — e.g. { output_bg, edge_feather } for bg-remove, { question, file_key, prior_messages } for chat-pdf. target_lang string Optional — translation target language for subtitle-generate (top-level, NOT in ai_options).
