Basis Theory
Basis Theory is a PCI Level 1 compliant tokenization and data vault platform. Its API-first product lets developers tokenize, store, and use sensitive data - cardholder data, PII, PHI, and bank account numbers - without that data ever touching their own systems, using tokens, a detokenizing Proxy, serverless Reactors, and 3D Secure authentication.
Basis Theory publishes 10 APIs on the APIs.io network, including 3D Secure API, Applications API, Logs API, and 7 more. Tagged areas include Tokenization, Data Vault, PCI Compliance, Payments, and Security.
Basis Theory’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.
