While I have not used this API myself, the Blockfrost API has a JavaScript SDK that can do that. There is a free tier.


Ogmios runs alongside a cardano node and provides a websocket api to sync or query the chain. Documentation is available here. If you don't want to host the node yourself, or want to get up and runnning as quickly as possible, you could check out the instance hosted by Gimbalabs


Nami wallet injects a bunch of functions yo your browser, similar to meta mask:



You can also interact with cardano blockchain via cli, and there is a nice library that i use personally a lot named cardanocli-js
