# Magic Auth > Verified-identity infrastructure by TS Robotics Limited. Four products behind one REST API: Verify (document and biometric identity checks to the IAL2 standard), Sign (advanced electronic signatures over a document hash), Authenticate (passwordless OIDC sign-in and a TOTP authenticator), and Vault (a zero-knowledge password vault). The same app is co-branded for every relying party. Production API base: https://api.magicauth.ai. Magic Auth is business-to-business. Access is issued on request during onboarding; it is not self-serve. Contact admin@tsrobotic.com. Hosting is Google Cloud in London (europe-west2). Data is encrypted in transit with TLS and at rest with customer-managed keys. Signing keys are held in a hardware security module and receipts are cryptographically signed and independently verifiable. Every tenant is isolated at the database layer with enforced row-level security. The Vault is zero-knowledge: the server only ever holds ciphertext it cannot read. Authentication to the API is a bearer key issued at onboarding, and every mutating call carries an Idempotency-Key header. ## Pages - [Home](https://magicauth.ai/): Platform overview, the four products, and how to integrate. - [Products](https://magicauth.ai/products): Verify, Sign, Authenticate and Vault in detail. - [For AI agents](https://magicauth.ai/agents): Structured, citable facts, an integration guide, and an FAQ written for AI agents and crawlers. - [Developer docs](https://magicauth.ai/docs): REST API reference, authentication, and idempotency. - [Pricing](https://magicauth.ai/pricing): How Magic Auth is priced. - [Portal](https://magicauth.ai/portal): The customer portal and per-tenant usage metering. ## Legal - [Privacy Policy](https://magicauth.ai/privacy): Data processing, roles, legal bases, retention, security, and rights. - [Terms of Business](https://magicauth.ai/terms): The terms on which the platform is supplied. - [Cookie Policy](https://magicauth.ai/cookies): Cookies and similar technologies. ## Optional - [Full description](https://magicauth.ai/llms-full.txt): The complete plain-text description of Magic Auth in one document.
