What responses look like

Trimmed for brevity — every payload arrives in a consistent envelope that tells you when it was fetched and whether it came from cache.

Ask for what a company does

Sector labels say what a company is filed under. They can't tell you where it operates, what else it produces, or who it sells to. We read every company's own description and store those as facts you can query — in parameters, or in a sentence.

why NEM: operatesIn=Canada · products=copper
“It also explores for copper”
  • The head-office trap, handled. Ero Copper is registered in Vancouver and mines in Brazil. Filtering on country returns it; asking where it operates does not.
  • One label is never enough. Newmont is filed under gold — but it produces copper and operates in Canada, so it belongs in this answer. A single industry field can't hold that.
  • Every row shows its receipts. Each match reports the facts that put it there and the sentence each came from, so you can check the answer instead of trusting it.
  • The model only translates. It turns your sentence into the filter and stops. It never picks the companies, never ranks them, and never writes the summary — so it cannot invent a holding that doesn't exist.

Same query available as parameters, as a sentence, or as the find_companies MCP tool.

Built for AI agents

Beyond REST, the same data is exposed as a native MCP server — 19 intent-scoped tools an LLM can discover and call directly, with typed parameters and consistent schemas.

  • One key, both surfaces. The same credential authenticates REST and MCP.
  • Smart caching. Immutable history is stored permanently; live data refreshes on sensible clocks.
  • Consistent envelopes. Every response tells you what it is, when it was fetched, and whether it was cached.
  • Answers you can audit. Every matched company reports which facts put it there, and the sentence each fact came from.
