13FLOW is operated by l0g: an independent research and data lab focused on macro risk, markets, public data and machine-readable financial intelligence.
l0g is an independent open research project that turns public macro, market and regulatory data into dashboards, methodology notes, machine-readable endpoints and source-linked analysis. Its work is deliberately source-first: primary data is preferred, methods are documented, and uncertainty is kept visible instead of being hidden behind a glossy score.
13FLOW is one of those tools. Where l0g.fr tracks macro regimes, debt risk and public datasets, 13FLOW focuses on SEC filing intelligence: 13F institutional ownership, Form 4 insider disclosures, data-quality warnings and integration surfaces for analysts who want evidence before narrative.
Why this exists
For analysts
Reduce SEC filing noise into a reviewable queue: who moved, which issuer changed, what source filing supports it, and where the data can be wrong.
For builders
Expose stable read-only contracts for dashboards, notebooks and agent workflows without pretending the signal is validated alpha.
The product stance is conservative. 13FLOW prioritizes workflow, structure and auditability. It does not present a magic trading signal, a probability model or a performance promise.
Operating principles
01Use public regulatory sources first, especially SEC EDGAR for the filing layer.
02Show the boundary: delayed 13F snapshots, incomplete short exposure, mapping gaps and Form 4 limits.
03Keep human-readable pages and machine-readable contracts aligned.
04Separate evidence from claims: validation pages say what is proven and what is still only a hypothesis.
