    This is absolutely detailed and informative one. In addition to that, here’s a new API which is called Faast Swap API (https://api.faa.st/) I have known and trying to apply this new one. This could allow you to essentially create your own one-stop shop for swapping 100+ cryptocurrencies on your platform, powered by their technology of course. This is helpful as well to anyone who wants to monetized their own website as mentioned.

    I’m a Co-Founder of https://blockfacts.io — we just added our API to Rapidapi and it has become quite popular already. We provide compliance-first market data with tick level access and full lookthrough, we’re currently in free Beta and looking for feedback on the product! Would be nice to be added to the article. Cheers, Gus

    This list is quite detailed indeed, but I have used a bitcoin API with the lowest global service charge, b.app, 0.5% service charge, mutual transfer between wallets does not need miner’s fee, there is also the function of automatic exchange of stable currency, and the experience is very good.
