keri request authentication method
Definition
All requests from a web client must use KRAM (KERI Request Authentication Method) for replay attack protection. The method is essentially based on each request body needing to include a date time string field in ISO-8601 format that must be within an acceptable time window relative to the server's date time. See the KRAM Github repo
