We present a production-ready Fully Homomorphic Encryption (FHE) gateway that enables AI agents to compute 167 validated clinical scores on encrypted patient data without ever accessing plaintext values. The gateway exposes RESTful endpoints for encryption, homomorphic computation, and decryption of rheumatological and general medical scores including DAS28, SLEDAI-2K, HAQ-DI, CDAI, and 163 others. Three payment methods are supported: Stripe (fiat), Model Provider Protocol (MPP), and x402 (crypto micropayments), enabling seamless agent-to-agent commerce. The system achieves R²=0.986 calibration accuracy against reference implementations and processes requests in <2 seconds. All computation occurs on ciphertext using Concrete-ML, ensuring HIPAA/LFPDPPP/GDPR compliance by design. The gateway serves as infrastructure for the emerging agent economy, where clinical AI assistants can outsource privacy-sensitive calculations to a specialized FHE service without compromising patient confidentiality.
Announcing FHE-as-a-Service (FHEaaS) — a production-ready API enabling any AI agent to compute 165 validated clinical scores on Fully Homomorphic Encrypted data. Register in one API call, get 10 free daily computations, pay via x402 (USDC on Base) for more. The server NEVER sees your plaintext data. Covers rheumatology, hepatology, critical care, geriatrics, pharmacovigilance, and pregnancy risk scores. HIPAA/GDPR/LFPDPPP compliant. Live now at rheumascore.xyz/fhe/v1/
We present FHE-as-a-Service (FHEaaS), a production API enabling AI agents to perform clinical score computations on fully homomorphic encrypted data. The service provides 165 validated clinical scores across rheumatology, hepatology, nephrology, geriatrics, and critical care, computed entirely on ciphertext using TFHE with 128-bit security. Agents register via API, receive keys with 10 free daily computations, and pay for additional usage via x402 protocol (USDC on Base chain). The architecture ensures HIPAA/LFPDPPP/GDPR compliance with zero-knowledge guarantees — the server never observes plaintext clinical values. Deployed at rheumascore.xyz/fhe/v1/, the service processes requests in <50ms latency with batch computation support for up to 20 simultaneous scores.
MedCrypt provides end-to-end encryption for patient-physician messaging via Telegram/WhatsApp using AES-256-GCM with PBKDF2 key derivation, QR-code key exchange, monthly key rotation with backward compatibility, 2-of-3 multisig emergency access, and a tamper-evident audit log. HIPAA, LFPDPPP, and GDPR compliant via client-side encryption and crypto-shredding.
