Private beta · Q4 2026 Azure Spain Central, Madrid

The OpenAI- and Anthropic-compatible AI API that keeps your data where it belongs.

Designed for Azure Spain Central (Madrid). Each project sets its residency tier — Spain, EU or global — and the gateway enforces it on every request: if no allowed route is available in that tier, the request fails instead of leaving it. The catalogue shows which models have a verified route in each tier.

ES ⊂ EU ⊂ Global. One tier per project, enforced on every request.

A project on the EU tier may use EU and Spain routes, never global ones. If every allowed route fails, the gateway returns an error instead of looking for an alternative outside. Pick a tier and simulate a failure.

Conceptual diagram, not a geographic map. Each ring contains the inner ones: ES ⊂ EU ⊂ Global. The gateway sits at the centre, in Madrid.

Served by Amazon Bedrock (EU) on the first attempt.

—Anthropic API (Global) is never tried: it is outside the project's EU tier.

Fallbacks only go to routes in the same or a stricter tier. Never to a looser one. Retries happen only before the first byte is streamed to the client.

The platform

Azure Spain Central, Madrid

Gateway, control plane, console, metrics and credit ledger run in the Madrid region. This is the ENS scope.

The model

Whichever endpoint the tier allows

The project’s residency tier decides: a regional endpoint in Madrid, in the EU, or global. The model provider is a sub-processor and is listed as one.

Residency and compliance in detail

A console for the people accountable for AI use.

Projects, keys, budgets, usage and billing in one place, with the residency tier visible in every view.

Project residency — Each project sets its tier — Spain, EU or global — and the console shows which models and routes remain available at that tier. — Real console with demo data.

The provider’s list price. No token markup.

Each route costs what its provider publishes, converted to euros. Situra charges a transparent fee on credit top-ups.

Change the base URL and the key. That’s it.

The official OpenAI and Anthropic SDKs, curl and Claude Code work as they are. The project decides residency, not your code.

The x-situra-residency header is optional and can only tighten the project’s tier, never loosen it.

claude 

Claude Code sends the key as Authorization: Bearer; Situra also accepts x-api-key. Pin the models with the ANTHROPIC_*_MODEL variables: by default Claude Code asks for dated IDs (claude-haiku-4-5-20251001) that Situra does not recognise. The models must be allowed in the project, and the project’s tier decides where they run.

Security you can check.

Each control is described in enough detail to verify it. The trust center brings together the architecture, the real compliance status, sub-processors and documents.

Staff never see content: No internal API returns prompts or responses. Content logging, if enabled, is encrypted under the organisation’s key.
Hash-chained audit log: Append-only; every row carries the hash of the previous one. The chain can be verified and exported.
Four-eyes approval: Suspensions, credit adjustments, provider credentials and second-factor resets need a second approver.
Residency attestation: Every response carries signed evidence of where it was processed, verifiable with our public keys.

Frequently asked questions

We are looking for three to five organisations for the beta.

Spanish public administrations and regulated organisations that want to use AI models with data residency under control. We work with each organisation on ENS categorisation, the DPA and the integration.
