How to merge multiple JSON in one?

Hello.

The site has a news feed which contains multiple sources. How to combine all JSON(REST API) files in one sorted by date and cache it on my services and to give the website a single JSON file?

Different sources, such as: Telegram(2 different channels), VK, WordPress Site, Medium, Behance, etc.
