CloakAPI is a privacy-preserving AI gateway. Prompts are tokenised before they leave your machine. Every call produces a signed, verifiable receipt.

CloakAPI is a drop-in replacement for direct calls to Anthropic, OpenAI, Google, and other AI providers. Customer prompts are tokenised at the edge before reaching the gateway. Every successful and failed call returns a chain-linked ECDSA-P-256-signed receipt, verifiable offline using only our public key.

CloakAPI is an EU-based privacy-preserving AI gateway. The product solves a structural privacy problem: when an application calls a model API, customer PII flows directly to the upstream vendor with no possibility of audit. CloakAPI tokenises that PII at the edge — before it leaves the customer's environment — and substitutes provider-stable placeholders. The gateway then attaches a chain-linked signed receipt envelope to every reply. Every receipt is verifiable offline by any auditor using ECDSA P-256 / SHA-256 against a published JWKS. No CloakAPI account required for verification.
