 # Payment
 Customers SHOULD pay service providers whose job results they accept by zapping the Service Provider and tagging the `kind:68002` job result.
 
+Additionally, if a service provider requests full or partial prepayment via a `kind:68003` job-feedback event, the customer SHOULD zap that event to pay the service provider.
+
+# Cancellation
+A `kind:68001` job request might be cancelled by publishing a `kind:5` delete request event tagging the job request event.
 
 # Job chaining
 A Customer MAY request multiple jobs to be processed in a chained form, so that the output of a job can be the input of the next job. (e.g. summarization of a podcast's transcription). This is done by specifying as `input` an eventID of a different job with the `job` marker.
 
 Service Providers MAY begin processing a subsequent job the moment they see the prior job's result, but they will likely wait for a zap to be published first. This introduces a risk that Service Provider of job #1 might delay publishing the zap event in order to have an advantage. This risk is up to Service Providers to mitigate or to decide whether the service provider of job #1 tends to have good-enough results so as to not wait for a explicit zap to assume the job was accepted.
