api-key string

NOWNodes API key passed in the api-key header.

Changed. New optional body field xcmVersion (integer): the XCM version used to encode the XCM programs in the dry run result. It is used only on runtimes whose dry run API takes this parameter; when omitted, the chain's safe XCM version is used. Before, the endpoint failed on such runtimes.
