These come up in the same searches but do not get a full row above, because not every column is something we can check on their own site. Here is what is verifiable: what they cover, what they cost and how an AI agent reaches them.
| Product | Covers | Price | Agent access |
|---|---|---|---|
| Fintel | Insider trading, institutional ownership (13F and 13D/G), short interest, options flow and its own quant scores | Free tier plus paid tiers (Bronze, Silver, Gold). The amounts render inside the app, so check fintel.io/checkout for the current figures | Public API for developers. No MCP server found |
| VerityData | InsiderScore | US insider transactions with a long history, plus buybacks, equity grants and institutional ownership. InsiderScore is now a module inside VerityData rather than a standalone product; insiderscore.com forwards there | Not publicly listed, contact sales. There is no self-service tier | Ships its own MCP server, but it needs a VerityData account |
Fintel
The closest overlap with us on insider and institutional data, and it scores signals itself. What we add on top is congress trades, 8-K events, Form D raises, biotech and FDA catalysts, and agent access over MCP.
VerityData | InsiderScore
The deepest insider dataset of these and aimed at institutional desks. Worth being straight about: they also offer an MCP server, so agent access as such is not unique to us. What differs is that ours starts free and self-serve instead of through sales, and covers congress, Form D, FDA and app-store signals as well.
