OCP is based on Kubernetes. In Kubernetes you have the CronJob resource, which seems to be what you're looking for for your resource and allows you to run a job on a specific schedule.
As you need to use curl, you can use the curlimage/curl image, which has the curl binary included:
apiVersion: batch/v1
kind: CronJob
metadata:
name: my-curl-job
spec:
schedule: "* * * * *"
jobTemplate:

restartPolicy: Never
