xAI's API security FAQ states that xAI never trains on API inputs or outputs without explicit permission, and that requests and responses are stored encrypted at rest for 30 days for abuse-auditing purposes before automatic deletion. Zero data retention is a self-serve toggle a team admin can enable from the xAI Console, applying automatically to all of that team's API keys. xAI states it is SOC 2 Type 2 compliant and offers a Business Associate Agreement on request via a BAA questionnaire; no FedRAMP authorization is published. The Data Processing Addendum states personal information is processed in the United States; this audit could read that page's existence and title but the live fetch returned a 403 during the audit, so the residency claim here rests on the DPA's indexed description rather than a direct read.
