FastSaverAPI is now at api.fastsaver.io

the product

one API key, one request shape

• Send a link and your X-Api-Key. Get JSON with a direct download URL.
• No cookies, no proxies, no headless browser, no watermarks.
• Nine platforms behind two endpoint shapes — /fetch and the YouTube family.
• Telegram file_id for cached audio, so a bot replies without touching the file.
• Pay per request: 1–25 credits depending on the call. Free tier is 1,000 credits, no card — see plans.
