Aster Lang APIPolicy Engine REST API & Developer Documentation

Evaluate business policies written in natural language via a simple REST API

⚡

Policy Evaluation

Evaluate CNL (Controlled Natural Language) policies via REST, GraphQL, or WebSocket. Submit policy source inline or reference a stored policy by ID. Supports batch evaluation for high-throughput workloads.

🔒

Audit & Compliance

Every evaluation produces a tamper-evident audit record with SHA-256 hash chaining. Administrators can verify the integrity of the full audit log at any time, satisfying regulatory and compliance requirements.

🏢

Multi-tenant

Built-in tenant isolation ensures each organisation's policies and audit records are fully separated. Role-Based Access Control (RBAC) with HMAC request signing protects every endpoint.
