Why StockAlloy

Section titled “Why StockAlloy”

Most financial data APIs give you a number. StockAlloy gives you the number and the proof: every fact row carries an evidence_url that opens the actual SEC filing with the exact figure highlighted. When your AI product quotes Deckers’ direct-to-consumer revenue, your users — and their compliance teams — can click through to the 10-K table cell it came from.

{
  "metric_label": "Revenue",
  "period_end": "2024-03-31",
  "value_num": "4287763000",
  "source_form_type": "10-K",
  "source_filed_at": "2024-05-24",

}

Verified, not scraped

Facts are extracted from official SEC XBRL and iXBRL filings and span-verified against the filing HTML — the value in our database is the value displayed in the document.

Evidence links on every number

Each fact carries a stable evidence_url that opens the source filing with the figure highlighted. Provenance is the product, not an add-on.

Segments, products, geography

Beyond headline metrics: full dimensional breakdowns (business segments, product lines, regions) plus operational KPIs like launch counts and backlog.

Built for AI products

A small, legible REST surface plus an MCP server so Claude and other agents can pull cited facts directly into answers.
