AION API Gateway
Three access tiers. One source of truth for eligibility. All model subscriptions route through the same gateway infrastructure.
Website-Owned Access
Public-facing surfaces — research, model pages, open-source documentation, and the public risk radar — are accessible without an account. No key required. No login wall.
Includes: /research, /models/*, /open-source/*, /sentinel/risk-radar.json
Model-Scoped API Keys
Developer API access requires identity verification and passkey registration. Keys are issued per model — an Indian Market Intelligence key does not carry Edge Engine access. Scope is enforced at the gateway, not by convention.
Required: Account creation + passkey registration
Premium Access
Paid plans are provisioned through Razorpay checkout. PostgreSQL is the source of truth for subscription eligibility. Plan downgrades take effect at the end of the active billing cycle.
Required: Account + passkey + active Razorpay subscription

Eligibility Architecture
AION uses PostgreSQL as the single source of truth for subscription state. The gateway reads current eligibility on every authenticated request — there is no cached entitlement layer that can diverge from billing state.
- Passkey registration is required before any API key is issued. AION does not issue keys on email/password credentials alone.
- API keys are model-scoped and non-transferable. A key issued for Indian Market Intelligence will be rejected by the Edge Engine endpoint.
- Premium subscription state is checked against Razorpay webhook receipts stored in PostgreSQL. Keys are not manually provisioned.
- Revocation is immediate. Cancelled subscriptions lose access at billing cycle end, not key rotation.
