How enterprise and sovereign quotes are built. Your figure starts from the published band above and is set by a few variables: number of seats, API throughput, deployment model (shared, hybrid, on-premise, or air-gapped), integration and white-label scope, jurisdiction, and support level. There is no open-ended blank; the starting bands are real and every quote traces to them.
The complete option register, with the full value architecture, is published for download: Product and Service Catalog (XLSX) and Full Value Architecture and Monetization Register (XLSX).
What to expect, and what to do if something goes wrong
When you subscribe
Checkout is handled by Stripe. After payment you return to your ETHRAEON account, where your plan is active. API plans issue a live API key on checkout; platform and Adhesion plans provision your workspace.
Currency and tax
Platform and API plans show a USD and a EUR option. Seminars support USD, EUR, GBP, and CHF. Applicable tax is calculated at checkout. Need a formal invoice or purchase order? Ask us before you buy.
If checkout does not complete
If a payment is declined, a page does not load, or you do not receive your key or workspace, nothing is charged twice. Reach contact.ethraeon.ai with the plan name and we will complete it manually or correct it.
Changing or cancelling
Monthly subscriptions can be cancelled anytime from your account and stop at the end of the period. To move up or down a tier, or to convert a trial, start a short briefing and we will migrate you without losing your evidence history.
