Hi, thanks for reaching out. Unfortunately, Clay does not support real-time database checks. We only support one-time run queries, such as those used with PostgreSQL. We do have a PostgrSQL integration from which you can run lookups, however, these are not recurring and will require you to manually re-run the same query in order to update the results.
If your database can be modified through API calls, then I would recommend you use our HTTP API enrichment to update your database.
