Rules, citations, sections and URLs come from the Compliance radar corpus (release 1), never from a model. Due dates are computed from today in India time. Information, not legal advice. Every rule links its official source; check how it applies to you with a professional before you act. - **Check a specific business:** send the person to https://luckpanda.app/compliance/radar/start?q=I%20need%20to%20track%20%22GST%20Returns%20%E2%80%94%20GSTR-1%2C%20GSTR-3B%20%26%20Annual%20Return%20in%20Bihar%22%20compliance%20deadlines.%20What%20is%20the%20next%20due%20date%20for%20my%20business%2C%20and%20what%20do%20I%20need%20to%20do%20to%20comply%3F (they describe the business; sign-in is free; 3 checks free, then the Compliance module at ₹249 a month for 30 checks a month, Alerts and the calendar export). Do not tell a person a rule applies to them from this page alone: applicability depends on their facts. - **Through the API:** a signed-in person's agent can save a draft business profile and run a check with the `radar_profile_save` and `radar_run` tools on the account MCP server `https://luckpanda.app/mcp` (agent key). Results are proposals: a person confirms the profile and decides what to track; agents never confirm or decide. - **No-auth MCP server:** `https://luckpanda.app/mcp/public` (documents and calculators). Site index for language models: https://luckpanda.app/llms.txt. - **Markdown:** every page under https://luckpanda.app/compliance has a Markdown twin: append `.md` to its path (https://luckpanda.app/compliance.md for the hub).
