AION API Gateway

Three access tiers. One source of truth for eligibility. All model subscriptions route through the same gateway infrastructure.

Tier 1

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

Tier 2

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

Tier 3

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.
