OpenAI's data controls documentation lists /v1/responses and /v1/chat/completions among the Zero Data Retention eligible endpoints and lists /v1/agents, alongside /v1/assistants and /v1/threads, among endpoints that retain application state regardless of ZDR settings; the EU region eu.api.openai.com offers in-region storage and processing.

Why it matters

It shows the split is endpoint-level inside one vendor, so a team can be compliant on one call and transferring on the next without changing provider, contract or key.
