# Operations

The HTTP `POST` method called on the certificate URL is a RPC API. That API is organized around "operations."
Each operation can be called with parameters in the JSON request body. The HTTP response body contains the result
of each specified operation. The structure of the parameters and response is symmetrical. That is, the parameters
are echoed back in the response. The operation response body also contains a `result` property that returns the
outcome of the operation.

**IMPORTANT:** Each operation is contracted separately so you may not be able to use them all. Additionally, each operation is
billed separately has incurs a unit cost each time the operation is run.

If you are using this API in a ping/post lead buying arrangement, you might consider using only the `insights`
operation on ping and the `retain` operation on post. That way, you can use the insights data points to inform
your bid price. If you win the auction for a lead you will then store the certificate on post using the `retain` operation.
