Overview
One subscription opens two views: the contract you hold on the index, and the market that sets it.
Contracts
Each contract has its own page, from the day it is signed to the latest settled month.
The referenceThe index or blend named in Schedule A, followed from its base level through every month since signing.
Monthly settlementEach month’s settlement figure beside the published levels that produced it, so both parties invoice and pay on one number.
Settlement APIThe same figure by API, ready for the vendor’s billing system, with manual entry as the fallback.
The recordBasket composition and every admission decision behind each settled level, so any figure can be traced to its prices.
BudgetingWhere the contract sets prices a quarter ahead, the next quarter’s rate shows as soon as its reference period closes.
Newer modelsWhen volume moves to a successor model, its starting price and the indexation carried across are recorded on the contract page.
Tailored indexes. Where no published index covers the models or vendors a contract buys, Attic Standard builds one under the same methodology and governance, and shows it privately to both parties.

Every subscription includes both views of the Terminal. A subscription starts once the contract terms are agreed, and the vendor party reads its contract page and settlement figure at no charge.
Attic Standard runs on SOC 2 Type II certified platforms and ISO 27001:2022 certified storage, and inherits their controls; its providers also hold ISO 27017, ISO 27701 and GDPR compliance.
