Video Download API reference

Video Downloader API Documentation

Use the OpenAPI reference for first request setup, pricing links, and migration planning.

Use Video Download API to submit YouTube and supported video URLs, request MP3, MP4, subtitles, transcripts, or high-resolution output, then poll for a ready download URL. Find first cURL request guidance, the interactive OpenAPI reference, YAML and JSON spec downloads, API key authentication notes, usage-based pricing links, and migration context.

Download endpoint summary

Submit a video URL with format, url, and apikey to create an audio or video download job.

Progress endpoint summary

Poll with the returned job id until the API returns the final file URL and completion status.

First request

curl

Use this checklist to move from signup to a valid job ID without leaving the intro panel.

Get your API key
Create an account, then copy the dashboard-issued key you will pass as apikey on download requests and as api on subtitle requests.
Replace the placeholders
Replace YOUR_API_HOST with p.savenow.to, the default shared API host, unless your dashboard shows a custom account-specific hostname. Then set url, choose a valid format, and paste your real key.
Send the request
A successful submit returns success: true and a job id. Use that ID with GET /ajax/progress until the file is ready.

Required query params

format output type url video URL apikey dashboard key

curl "https://YOUR_API_HOST/ajax/download.php?format=mp4&url=VIDEO_URL&apikey=YOUR_API_KEY"

p.savenow.to is the default shared API host used in public examples. If your dashboard shows a custom API hostname, use that account-specific host instead.

What success looks like

Your first successful call should return a JSON object with a job ID you can poll. The final file URL arrives on the progress endpoint once progress reaches 1000.

{
  "success": true,
  "id": "abc123xyz789"
