This listing offers one pricing dimension: Product Access (Units). It is a free subscription that grants you access to the product. There are no tiers, seat counts, or usage add-ons to choose from. You subscribe once to gain access to the AHCI Member Watch Performance Index (AMPI) data. Because it carries no charge, pricing does not scale with usage, seats, or data volume. The single dimension covers all access under this listing.
Top-of-mind questions for buyers
What does one unit of Product Access grant me?
One unit grants your account access to the AHCI Member Watch Performance Index (AMPI) data under this listing. Access is subscriber-based and tied to the account you subscribe with. There are no separate seats or per-user allocations to configure under this free dimension.
Does my cost change as I query more data or add more usage?
No. This dimension carries no charge, so your cost does not rise with data volume, query frequency, or usage over time. There are no included-amount cutoffs or overage points that trigger added fees. Access remains free regardless of how much AMPI data you pull.
What type of data does this AMPI subscription cover?
The subscription grants access to the Global AHCI Member Watch Performance Index. This tracks watch market performance using auction and private-sale records, refreshed as new results come in. The data covers realized transaction results rather than asking prices or estimates.
