Evervault

Evervault is a data-security and payments-infrastructure platform that lets developers encrypt, tokenize, and process sensitive data - especially cardholder data - without it touching their own infrastructure. Its model stores encryption keys on Evervault's side while customers hold the ciphertext, reducing breach scope. Core products include Relay (an encrypting/decrypting proxy), Functions (secure serverless runtimes), Enclaves (AWS Nitro Enclave workloads), UI Components for PCI-compliant card collection, plus payments tooling: network tokens, 3D Secure, BIN lookup, card account updater, and multi-PSP routing. Evervault is PCI DSS Level 1 and SOC 2 Type II, and supports HIPAA and GDPR.

Evervault publishes 12 APIs on the APIs.io network, including 3D Secure API, Acquirers API, Card Account Updates API, and 9 more. Tagged areas include Company, Data, Security, Encryption, and Payments.

The Evervault catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Evervault’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, changelog, and 28 more developer resources.
