Is OpenRouter US-only?

No. On the Business plan, OpenRouter serves requests to eu.openrouter.ai only from shared provider endpoints in Europe (the EU/EEA, the UK, and Switzerland), and requests to us.openrouter.ai only from shared provider endpoints in the US. The default domain, openrouter.ai, routes globally. If your own BYOK key serves the request, it goes to your cloud deployment, in the region you set.

Does EU routing need Enterprise?

No. EU in-region routing is included in OpenRouter Business, which an organization admin upgrades to from settings with no contract and no monthly minimum; Business adds an 8% platform fee on credit purchases. Enterprise includes in-region routing as well, with a custom agreement.

OpenRouter is a US company: what about data transfers?

OpenRouter is a US company. Requests sent to eu.openrouter.ai are decrypted in the EU and routed only to shared provider endpoints in Europe (the EU/EEA, the UK, and Switzerland), so prompts and completions are processed there. Account, billing and operational records may be stored and processed in the US, and those transfers are covered by the DPA, which incorporates the EU Standard Contractual Clauses. Requests served by your own BYOK key go to your cloud deployment, whose region you set. The Data Processing Agreement applies to your organization through the Terms of Service; Business customers can request a signed copy from settings.

Is OpenRouter GDPR compliant?

OpenRouter supports GDPR programs. The controls are EU in-region routing, data-region guardrails and Zero Data Retention; the Sovereign AI guide shows how to combine them.

Which models are available on eu.openrouter.ai?

69 models from 5 providers are available through eu.openrouter.ai. The table on this page is read hourly from the EU Models API (GET https://eu.openrouter.ai/api/v1/models).

What happens if no EU provider is available?

The request fails with an error; it is never routed to a shared endpoint outside the region. In-region routing fails closed: if no eligible endpoint is onboarded for the model, or a feature in the request would process data outside the region, OpenRouter returns an error instead of falling back. Requests served by your BYOK key go to the deployment it is configured for, and OpenRouter does not verify where it runs: provision it in the region you need and follow the provider-specific BYOK steps.

Does OpenRouter store my prompts?

Not for requests sent to eu.openrouter.ai: OpenRouter input/output logging is skipped for every regional endpoint request, even when it is enabled. Providers handle prompts under their own data policies; turn on Zero Data Retention to route only to endpoints that do not retain them.

What is processed where

In-region routing covers API payloads sent to eu.openrouter.ai. It does not move account or operational records, and it cannot change where resources you control are hosted.

Processed in Europe (requests to eu.openrouter.ai)

Prompts and completions, decrypted in the EU and routed only to shared provider endpoints located in Europe (the EU/EEA, the UK, and Switzerland). Requests served by your BYOK key go to your own deployment instead.
Endpoint selection: only shared endpoints onboarded for the EU region are candidates, so a request with no eligible endpoint fails instead of leaving the region.
Server tools that run entirely in-region, such as tool search, datetime, and apply patch, and native PDF parsing.
Broadcast traces for EU requests, sent from infrastructure inside the region and never queued outside it.

Account and billing metadata

This card covers account, billing and security records. Prompts and completions sent to eu.openrouter.ai are processed in Europe, except requests served by your own BYOK key, which go to your deployment.

Account data, billing records, and authentication data.
Security logs, abuse-monitoring metadata, and other operational records.

What you configure

Sending EU workloads to eu.openrouter.ai, and enforcing it with a data-region guardrail.
BYOK: where your own Bedrock, Azure, or Vertex deployment runs, and each key's region settings, which differ by provider. Regional routing and guardrails do not verify or move resources in your account.
Broadcast destinations: host your collector, Langfuse instance, or bucket in the EU if observability data must stay in the region.

How it works

How EU in-region routing works

Endpoint you call

eu.openrouter.ai

Routed only inside Europe

Shared provider endpoints in the EU/EEA, the UK and Switzerland.

No endpoint in Europe

The request fails rather than leaving the region.

Same key, same account
There is no separate EU account or EU key. The API key you use on openrouter.ai works on eu.openrouter.ai once your organization is on Business.
Change the base URL
Point your client at https://eu.openrouter.ai/api/v1. The request is decrypted in the EU and only shared provider endpoints in Europe (the EU/EEA, the UK, and Switzerland) are eligible to serve it.
Fails closed
If no eligible endpoint is available for the model, the request errors instead of leaving the region. OpenRouter never silently falls back to a shared endpoint outside the region. Requests served by your BYOK key go to the deployment it is configured for, so keep it in the region you need.
Out-of-region features are rejected
Features whose infrastructure processes data outside the region return an error on eu.openrouter.ai: web search, web fetch, files, image generation, Fusion, shell, sandboxed bash, PDF engines other than native, the Batch API (its jobs run on US-based storage and queueing infrastructure and are only accepted on openrouter.ai), and multi-model routers such as the Auto Router.

Enforce it

Enforce EU routing with a data-region guardrail

The base URL is a per-request choice. A guardrail makes it a rule, at the workspace, member, or API-key level.

1
Workspace
Set Data regions to EU on the workspace default guardrail. Every request in the workspace must then arrive through eu.openrouter.ai.
2
Member
Assign a guardrail with Data regions set to EU to an organization member. It applies to all of their API keys and chatroom usage.
3
API key
Assign a guardrail directly to a key. Guardrails intersect, so a key or member guardrail can only narrow the regions the workspace allows.

Shell

curl -X PATCH https://openrouter.ai/api/v1/guardrails/GUARDRAIL_ID \
  -H "Authorization: Bearer <OPENROUTER_MANAGEMENT_KEY>" \
  -H "Content-Type: application/json" \
  -d '{
    "allowed_data_regions": ["europe"]
  }'

A request that arrives through a domain the guardrail does not allow is rejected with 403 Forbidden before any inference or endpoint selection. Data-region guardrails require a Business or Enterprise plan. The guardrail value for the EU is europe; the Models API filter is region=eu.
