# Quintarthai

Cross-border equity research for North American markets, operated by Quintessentia Network Inc.
(Toronto, Ontario, Canada).

Quintarthai is a research tool. It returns factual market and filing data. It does not give
investment advice, does not make recommendations, and produces nothing tailored to an individual's
circumstances. See [disclosures](https://quintarthai.com/legal/disclosures.html).

## What it covers

- Roughly **51,000 US and Canadian listings**, including TSX and TSX-V.
- **Cross-border coverage** for issuers that file in both Canada and the United States - the
  deliberate focus of the product.
- SEC EDGAR-derived fundamentals, earnings history and corporate actions.
- Forward-looking IPO and economic-event calendars.
- A screener across the full North American universe.
- Mineral and mining-project data for junior resource issuers.

## For agents and developers

- [llms.txt](https://quintarthai.com/llms.txt) - what this site is, when to use it, and every
  machine-readable entry point. **Start here.**
- [OpenAPI 3.1 specification](https://quintarthai.com/openapi.json) - every public operation, typed.
- [Developer documentation](https://quintarthai.com/developers.html) - authentication and examples.
- [Plans and rate limits](https://quintarthai.com/api/v1/data/plans) - keyless, authoritative.
- [MCP endpoint](https://quintarthai.com/mcp) - Model Context Protocol tools. Separately gated: an anonymous request returns HTTP 401.

24 of the 52 published operations need no credential; the other 28 require an API key, which also raises rate limits.
