You mean the balance? If so, you can't check that for an address that is not yours. See this[1][2].

I have tried using some of the existing 3rd party API's but those are either too close or expensive or both, so was thinking about creating something myself locally.

I'm not sure what do you mean by "too close" but there are a lot of APIs that provide that functionality for free (Blockchair, Blockonomics, BTC.com, etc.). Which APIs have you tried so far?

Sorry, I've now clarified my question above.
