Sovereign intelligence infrastructure for India's diversity. AION Analytics Private Limited builds language- and jurisdiction-aware AI systems for markets, citizens and developers. This is the official GitHub organization for AION's open-source packages, public model documentation and research. Company website · Identity and scope

Canonical GitHub home: github.com/AION-Analytics-India. The separate AION-Analytics user profile is a secondary account, not another official organization or product catalogue. Use this organization for public releases, research and developer issues.

Flagship professional infrastructure: AION Intraday Infrastructure documents professional, licensed market-data processing, institutional quant analytics and proposed customer-isolated delivery. This is a documentation-only offer, not a retail trading product or a generally available signal lease.

These six projects represent AION's current public developer tools and product disclosures. Use the source repositories below, not the older documentation mirror or the secondary GitHub user account.

For published evidence, see AION Research. The market-calendar data repository supports both calendars but is not a separate end-user package.

This is the maintained publishing organization. Start from the code repository if you plan to inspect, fork or contribute; use the listed PyPI release to install. The older calendar documentation mirror is not the source repository.

• Python developers: inspect, fork or contribute to the Indian Market Calendar (source) or the Lithuanian Market Calendar (source). Both are MIT licensed; core calendar use does not require an AION account or API key. India on PyPI · Lithuania on PyPI
• AI and API developers: install the IMI client or MCP server. Installation is separate from the proprietary hosted service: inference requires credentials and model-specific entitlements. API catalogue and access
• Researchers: read AION Research, the canonical library and public validation records. Published findings, citations and limitations do not grant access to proprietary implementations.

Install the calendars from their canonical Indian and Lithuanian PyPI distributions:

pip install aion-indian-market-calendar aion-lithuanian-market-calendar

For example, compare settlement days using the documented India and Lithuania interfaces:

from aion_indian_market_calendar import is_settlement_day as india_settles
from aion_lithuanian_market_calendar import is_settlement_day as euro_settles

india_settles("2026-04-01")  # False
euro_settles("2026-04-03")  # False

Both packages automatically obtain published calendar-data updates through the shared versioned, hash-verified manifest contract. Supported online installations do not need a new PyPI release for each ordinary holiday or closure update. The normal refresh interval is daily; verified cached or bundled data provides fallback. Offline installations do not receive new data until a permitted refresh can succeed. Indian behavior · Lithuanian behavior and offline option

Next: developer documentation, institutional enquiries, or citizen services.

• Indian Market Calendar: MIT-licensed calendar and session utilities for Indian markets, including settlement-day and expiry-date interfaces. PyPI
• Lithuanian Market Calendar: MIT-licensed computed Lithuanian holidays, TARGET settlement-day utilities and exchange calendars using refreshed data. PyPI
• MCP Server: an AGPL-3.0-or-later-licensed wrapper for the hosted Indian Market Intelligence service. The wrapper license does not cover the proprietary inference service or confer API access. License · Access and entitlements

Recent calendar releases add practical interfaces for developers:

• India 1.7.1: trading versus settlement days, index-expiry and intraday phases, Muhurat sessions, plus commodity closing rules that distinguish US daylight-saving and standard-time seasons. MCX agricultural contracts require their own checks; published exchange notices remain authoritative. Release details
• Lithuania 1.2.1: Lithuanian statutory business days, TARGET euro settlement, market phases for supported EU venues, and timezone/daylight-saving utilities. Auction phases are not modelled; exchange-holiday updates remain distinct from statutory holiday calculations. Release details

These services have separate access conditions. Public client code does not include their proprietary models or implementations. The current product registry and API catalogue govern availability and plans.

• Indian Market Intelligence: financial headlines, circulars or notifications to structured sector-impact output. Hosted API with a credentialed free plan and paid plans; model-scoped quotas apply. Access · Demo
• Veritas: pre-open probability bands for NIFTY 50, BANK NIFTY and SENSEX, with public post-session receipts including misses. NIFTY 50 live access has a free 7-day trial (verified email and passkey, no card; 168 hours including non-trading days); continued or other-index access requires a subscription. Live bands are not public without an eligible key. A band is not a trade instruction. Trial and subscriptions · Public model card · Validation
• Sentinel: public filings to dated financial, cash-flow, governance and company-relationship evidence for human analyst review. Access is restricted; current sampling and institutional availability are stated in the catalogue. A screening result does not establish fraud or a regulatory violation.
• Edge Engine: supported index-option market data to structured per-contract statistical output with an as-of time. Paid API access; supported indices and limitations are in the catalogue.
• Signal Infrastructure: white-label signal-generation infrastructure leased as an API to eligible SEBI-registered Research Analysts, Investment Advisers and brokers. Not available to retail customers; no signal family currently qualifies for promotion. Pricing by enquiry.
• AION Setu (Order Execution Agent): execution events to a device-resident record for examining an automated order. Available through direct engagement on request, with no public download; it records orders and does not place them.
• Know Your Rights: Indian-law questions to cited legal information in English, Hindi and Gujarati. Public text-only pilot, not legal advice; new-question availability is governed by the live pilot page, which currently displays a temporary pause. Current pilot status · Public client and documentation
• Lithuanian Tax Assistant: entered Lithuanian income to tax calculations with cited legal provisions, in Lithuanian and English. Public pilot, not individualized tax advice.

• Calendar correctness: report a reproducible exchange/date discrepancy with a primary exchange notice and package version in the India calendar issues or Lithuania calendar issues. Source contributions follow each repository's CONTRIBUTING.md.
• MCP developer integration: test the public wrapper, file a focused issue, or suggest an example that does not disclose tokens or proprietary inference logic.
• Research corrections: use the research contribution process with a cited publication and reproducible evidence.

If a public tool is useful in your workflow, starring its source repository helps other developers discover that specific package; it does not affect AION access or support priority.

Report package defects and documentation mistakes through the relevant repository's issues and contribution guidance. Research corrections belong with the cited publication and its contribution process. For API, account or entitlement help, use AION's support contacts.

Do not post vulnerabilities, credentials or private data in public issues or Discussions. Follow the affected repository's published security policy where one is provided.
