YouTube Download API

Build with a YouTube video downloader API for download, MP3, MP4, subtitle, transcript, and metadata workflows, then start testing with a free API key before adding production credit.

Choose a format-specific integration guide for the YouTube to MP3 API or the YouTube to MP4 API.

From API key to file

Create a key, send a request, poll progress, and review usage through one predictable workflow.

Create or open an API key

Send the request

Use the documented REST or legacy-compatible endpoint with url, format, and the API key parameter.

Poll progress or consume the URL

Use progress_url or /ajax/progress.php. Below progress 1000 keep polling; at 1000 use download_url only when success is 1 or true, otherwise stop and show the error.

Review usage and balance

Track recent requests, coupon credits, top-ups, and payment callbacks from the dashboard.

Common questions

Where do examples run?

Use p.savenow.to for public API examples unless your dashboard shows a custom account hostname.

How do I add credit?

Open the dashboard, create a top-up payment, or redeem a coupon. Balance changes are shown in the account history.

Are old endpoints still supported?

Yes. The .php compatibility endpoints remain active for existing integrations and embedded clients.
