user130968: I'm working on a project that involves identifying sales and purchases in the Blockchain. Is there any way to do this with the blockchain.com API?

user5406: The blockchain only records transfers of Bitcoin, and there is no reason to believe that every payment is linked to trading activity. The blockchain does not record reasons why funds were transferred, and it most certainly doesn't record trading activity. How could it, when trading inherently involves the exchange for another good, service, or currency which per definition is not recorded on the Bitcoin network. It's not clear to me why you'd expect to be able to extract this information whatsoever.
