Choose Your AION API, Report, Or Package
AION offers three access tiers: Developer API Endpoints for model integration, Probability Reports for structured intelligence subscriptions, and Open-Source packages for calendar and utility use cases.
4-Step Access Flow
Choose your product
Pick the model and access tier below. Each model has its own scope and plan.
Verify identity
Create an AION account and complete passkey registration. API keys are model-scoped and require identity verification before issuance. (/access/register is a different path: it requires a referral code and is for approved dashboard and local-agent testers, not for hosted API keys.)
Checkout or install
Paid plans use Razorpay checkout. The Indian Market Intelligence free plan needs no card. Open-source packages install directly via pip — no account or API key required.
Use access
API keys are scoped to the selected model and plan features. PostgreSQL manages eligibility state. Keys do not cross model boundaries.

Package Documentation →Free tier
Indian Market Intelligence has a free plan: 10 requests per month, no card. The month is counted as a rolling 30 days. You need a verified email and a passkey, and each verified user can hold one free plan. Free keys are also limited to one per device and two per network (IP address) in any 30 days; a shared network can reach its limit before you sign up, in which case choose a paid plan or try later. Get a free API key.
Every other hosted product requires a paid subscription, and Veritas has no free tier. The Indian Market Calendar package is MIT-licensed open source and needs no account or key.
Validation receipts at /veritas/validation are public and always free — they are the accountability surface, not a product preview.
Scope Matters
Every hosted API key is scoped to the model and plan features selected at checkout. An Indian Market Intelligence key does not carry access to any other model. Keys cannot cross model boundaries — this is intentional design, not a limitation.
Veritas Single Index subscriptions are locked to the index chosen at checkout. Entitlement checks are server-side — the API returns only your entitled index regardless of what is requested.
Subscription eligibility is managed in PostgreSQL and enforced at the gateway level. Plan downgrades and cancellations take effect at the end of the active billing cycle.
