I found it yesterday, but thanks! Have a nice day!

Hi, is there a good way to get the runes data on the op.gg official website? It seems that there is no official api interface, I'm crawling the html page source code of the official website directly and using regular expressions to match the required runes ids.

OP.GG is not the official API for League of Legends.
If you want rune specific data, you can use Riot's Data Dragon source for patch specific information: https://developer.riotgames.com/docs/lol

There is a community project called Community Dragon that does more work behind the scenes and offers more data: https://raw.communitydragon.org/latest/plugins/rcp-be-lol-game-data/global/default/v1/
See perks, perk styles, etc.

And if you want rune specific data for games, you can use Riot's official API.
