Questions
Do I need a Crossref account?
No. Agentik holds the connection to Crossref; your agent calls it with your Agentik key and the call is paid from your balance at Crossref’s price.
Is the data the same as the direct API?
Yes. Each tool is one Crossref endpoint with its real inputs; Agentik adds the price check, the balance and the receipt, nothing else.
