Quartr

quartr.com/

Quartr structures real-time information published by public companies — earnings calls, transcripts, slides, and filings — into data feeds for investment professionals and AI applications, offered as both a research platform (Quartr Pro) and a raw data API. Its headline, "Everything said and published by public companies, structured for AI and delivered in real-time," is backed by specific coverage figures: 15,200+ companies across 62+ markets and 48M+ first-party documents. It states it's a founding data partner for OpenAI's ChatGPT Financial Services integration, and offers a dedicated MCP server connecting AI tools like Claude and ChatGPT to its company data — a specific technical integration most financial data providers don't surface on their homepage.
