Positioning

Why not sec-api, Financial Datasets or Dataroma?

Because 13FLOW should not pretend to be a cheaper clone of broad data APIs or retail portfolio pages. The wedge is narrower: a trust layer for agent builders and research ops that need source-linked filing evidence, quality boundaries and copyable API/MCP demos before any workflow relies on the data.

SEC EDGAR

official EDGAR JSON APIs and nightly bulk files

Why not just that: free official source makes raw filing resale indefensible

Use official filings as source truth; 13FLOW adds workflow structure, quality boundaries and source-linked review.

sec-api

broad SEC filing API suite for developers

Why not just that: a generic SEC API comparison turns 13FLOW into a commodity endpoint

13FLOW is narrower: a filing trust layer and research workflow surface, not a broad SEC API catalogue.

Financial Datasets

developer-oriented financial data APIs beyond SEC filing workflow

Why not just that: broad financial API catalogues are not the current 13FLOW wedge

13FLOW focuses on SEC filing evidence, not a broad market-data catalogue.

Dataroma

free curated superinvestor portfolio browsing

Why not just that: free curation absorbs casual retail interest

13FLOW keeps machine-readable source links and quality warnings visible for workflows.

ICP discipline

Primary ICP: agent builders and research operations.
Not retail. Not a discretionary analyst workbench as the generic headline.
Value claim: trust layer and workflow evidence, not signal alpha.
MCP is included only as a minimum public demo until it becomes a real supported product.
