Regions are isolated. An account, its API keys, and its data belong to exactly
one region — there is no cross-region access, and data is never replicated
between regions.
Endpoints
Use the endpoints for the region your account was created in.Using the EU region
SDKs
Point the client at the EU API by setting the base URL:REST
Call the EU host directly:cURL
Connect
Exchange an EU user token through the EU API, then send users to the EU Connect domain. The API and Connect hosts must stay in the same region:cURL
An API key is valid only in the region it was created in. A key issued from
app.hyperspell.com will not authenticate against api.eu.hyperspell.com, and
vice-versa. A one-time code issued by the US API likewise cannot be redeemed by
the EU Connect app.What stays in region
In the EU region, all of your content is stored and processed in AWS Europe (Ireland) and never leaves the EU:Storage
Your documents, extracted text, chunks, and vector embeddings live in EU-region
Postgres and object storage.
Embeddings
Embeddings are generated by an embedding model running in-region.
LLM inference
Summarization, entity extraction, and answer generation run on Amazon Bedrock
using EU inference profiles. Hyperspell does not call any model endpoint outside
the EU for EU-region content. Custom
answer_model selection (see
Manual Integration) is limited to models available in the
EU — choosing one that isn’t returns an error rather than routing your request
outside the region.Backups
Point-in-time backups of EU-region data are stored and replicated only within
the EU (across Availability Zones in Europe (Ireland)), never to another region.
Shared services
A small number of operational services are operated from the United States under the EU-US Data Privacy Framework. They process account and operational metadata — user identifiers, usage events, and error diagnostics — rather than your stored documents and memories:- Authentication (Clerk) — user identities and sign-in.
- Error monitoring (Sentry) — exception traces and diagnostics.
- Product analytics (PostHog) — usage events and identifiers.
