What are the advantages of owning a bitcoin node over free services with an API?

Question

API

The goal is to organize support for btc payments on several projects. We want the commission to be minimal for operations with funds.
We explore the subject area. A number of questions have arisen that cannot yet be resolved:
1) what is the best use of your node, and not the API of the same blockchain.com (will it be faster, will it be less commission, is it better in terms of security)
2) if someone breaks blockchain.com he will be able to steal $
3 with all wallets ) blockchain.com write that using their API is free - only a commission for miners - is that so? (this commission to miners is no more - than if you raise your own node?)

Answer 1

I personally have the same problem, but here's what I've already figured out. There is no method for sending payments in the blockchain.com API, only receiving and other information from the bitcoin blockchain. I searched the entire github and a bunch of sites, but I realized that there is no free API without limits on requests per second (usually 1 - 5 requests / sec). These are only for Ethereum. Therefore, its support is much easier than bitcoin. But if you are satisfied with these restrictions, then you can use ready-made solutions. A full node is only needed if you don't trust strangers or don't want any restrictions. But you will need a good and stable Internet + a lot of free disk space (from 300GB).

Answer 2

1) original source, no MiTM, etc.
2) it won’t be able to, but you can slap it on something else
3) the standard commission, as for any transaction, you can try to indicate less on your node

Answer 3

Thanks for the answers)
if you summarize it, it turns out - 1) safer 2) without time limits for requests (but clarifying comments still remained higher)
