I tried to retrieve my MySQL RDS binlogs in order to run manual "rollback" for some SQLs. Unfortunately, I noticed that only 2 binlogs for the last 30 minutes are available.
"call mysql.rds_show_configuration" provides "binlog retention hours | NULL".
I guess (because RDS provides ability to point-in-time restore between daily backups) that AWS RDS keeps its binlogs for 24 hours. But it seems that it's unavailable for the end user...
