Arklēon is a point-in-time SEC EDGAR fundamentals Data API: 426,003 filings, 181,350,662 facts, 16,811 companies, 69 quarters, as filed, as of their dates, from $179/month self-serve.

A dated record of 11 sectors, kept honestly.

Arkleon LLC sells a point-in-time SEC EDGAR fundamentals API with replayable as_of queries and per-figure lineage across 16,811 companies, plus a free open-source Python client and MCP server, and a sector intelligence web application. The two products are the fundamentals API and the sector intelligence web application.

What Arklēon tracks

Coverage spans 11 U.S. equity sectors: Technology, Energy, Finance, Healthcare, Consumer, Industrials, Utilities, Real Estate, Communication Services, AI and Innovation, and Defense and Security. Alongside sector sentiment, the platform provides stock screening, DCF valuations, and Monte Carlo projections.

Sentiment methodology

The pipeline runs one scoring pass per day. Each score is dated to the day it was produced and is never rewritten. Passes have been missed - between June 23 and July 21, 2026, most were - and the archive shows those gaps rather than filling them. The historical scoring methodology is under re-validation, and I will describe it here in full once that work concludes.
