Question: Is there a one-time payment solution that gives me lifetime access to a domain name database without any monthly fees?

If you're looking for a one-time payment option that grants you lifetime access to a database of domain names with no recurring monthly costs, One Word Domains is worth a look. It offers a list of 1,294,245 available and brandable one-word domain names across 93 extensions. For a lifetime payment of $149 USD, you get access to the full list, filtering and sorting features, and unlimited future updates. It's geared for startup founders and entrepreneurs who want memorable domain names.

Another service you could consider is PagePe, which can turn unused domains into content sites. It has different pricing levels, but the Ultimate tier ($99 lifetime payment) offers unlimited sites, auto-pilot publishing, support for custom domain and subdomain names and access to 13 content categories. It also automatically generates HTTPS SSL certification for custom domains, so it's a good option for creating and managing content sites without a lot of fuss.
