Introduction

What is Aether Citadel?

Aether Citadel is a privacy-first API that verifies AI intent signatures using zero-knowledge proofs. It ensures AI decisions are traceable, tamper-proof, and free of personally identifiable information.

Think of it as the security gate between your users and your AI — every AI interaction gets a cryptographic fingerprint, verified before it can affect your systems.

Why Aether Citadel?

Zero PII

Intent signatures are SHA-256 hashes of semantic context. No names, emails, or user data ever cross the boundary.

Bharat-Shield

India-first fraud detection that blocks replay attacks, intent spoofing, and AI hallucination injection.

Instant Integration

One header. X-Citadel-Key: ack_live_xxx — no SDK required, works with any HTTP client.

Compliance Ready

Designed for GDPR, India’s DPDP Act, and HIPAA-adjacent workloads. Audit logs on every verification.
