Public pricing preserved as one-to-many offers instead of a misleading single starting price
40 less-obvious operators deliberately included to counter famous-site bias
Initial release plus 2 monthly refreshes during 90 days

Build from observed patterns, then verify the source.

The Founding Edition is for comparing directory models and finding operating patterns worth investigating. It is evidence for a decision—not a promise of traffic or revenue.

Collection: Current official pages, official technical surfaces, and officially delegated first-party pages. Search could locate a source but could not replace it for a positive critical claim.
Unknowns: Kept as explicit states. Not observed after checking is not presented as proof that something never exists.
Quality: All 1,200 critical fields have matching evidence. A 20-profile, 2,800-field independent audit recorded zero errors; one pricing conflict remains visible instead of being forced into a false answer.
Updates: The initial release and 2 monthly versioned refreshes are available during the 90-day access period.

Method, limitations, and seller

Public websites and prices change. Counts can be promotional or lower bounds. Technology observations do not prove a commercial relationship. Re-check the cited source before a consequential decision. Sold by Directorygems, operated by Wei Yang as an individual/sole proprietor in California, USA.
