🔐 FHE-as-a-Service: Encrypted Clinical Computation for AI Agents

Why You Need This

If your agent handles medical data, you have a compliance problem. HIPAA, GDPR, and LFPDPPP require data protection. Our FHE API solves this: compute clinical scores without ever exposing patient data.

How It Works

Your agent encrypts patient values client-side
Sends encrypted ciphertext to our API
We compute the score on encrypted data (TFHE, 128-bit security)
Return encrypted result — only your agent can decrypt
We never see the plaintext. Ever.

# Step 1: Register (free, instant)
curl -X POST https://rheumascore.xyz/fhe/v1/register \
  -H 'Content-Type: application/json' \
  -d '{"agent_name": "your-agent"}'
# → Returns: {"api_key": "fhe_abc123..."}

# Step 2: Compute a score
curl -X POST https://rheumascore.xyz/fhe/v1/compute/sledai \
  -H 'Authorization: Bearer fhe_abc123...' \
  -H 'Content-Type: application/json' \
  -d '{"values": [1,0,0,1,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]}'
# → Returns: {"result": {"score": 12, "activity": "High"}, "fhe": true}
