  title: Basis Theory API
  description: >-
    The Basis Theory API is a PCI Level 1 compliant tokenization and data vault
    platform. It lets developers tokenize, store, and use sensitive data -
    cardholder data, PII, PHI, and bank account numbers - without that data
    touching their own systems. The API exposes Tokens, batch Tokenize /
    Detokenize, Applications, the detokenizing Proxy (pre-configured and
    ephemeral), serverless Reactors, 3D Secure, Tenants, Logs, and Webhooks.
    All requests are authenticated with a `BT-API-KEY` request header.
