Metric Duck

Financial Data You Can Trust

We're building the most accurate and transparent SEC data layer for AI agents — and the builders and analysts who run them.

Our Mission

Make financial data accessible, accurate, and trustworthy.

Too many builders struggle with unreliable financial data from free sources, or enterprise products gated behind sales calls and priced for institutions. We believe accurate, source-verifiable financial data should be accessible to everyone — including the AI agents now doing the reading.

Why We Built Metric Duck

We started by building financial-analysis agents ourselves — and kept hitting the same wall. Free APIs had errors, missing metrics, and outdated information. The reliable options were enterprise products: sales-gated, priced for institutions, and built for human terminals rather than programmatic access.

We asked ourselves: Why is accurate financial data so hard to get?

The answer: most platforms aggregate data from multiple middlemen, introducing errors at every step. We decided to build something different—a data layer that sources directly from SEC EDGAR filings, the official source of truth for US public company disclosures, and keeps a link from every number back to the passage it came from, so a human or an agent can verify any claim.

Our Approach

Direct from SEC Edgar

We parse data directly from 10-K, 10-Q, and 8-K filings using XBRL—no middlemen, no aggregators, no errors from third-party sources.

Link to Source

Every number on Metric Duck links to the SEC filing where it came from. You can verify our data yourself—we hide nothing.

Pre-computed Metrics

We calculate 323+ financial metrics (ROIC, WACC, FCF, ratios) so you don't have to spend hours in Excel. Our methodology is transparent and documented.

Transparency First

Every page shows "Last Updated" timestamps. We document our limitations. If we don't have data, we say so—no guessing, no filling gaps.

Our Values

  • •
    Accuracy over speed: We'd rather be correct than fast. Every metric is validated against source filings.
  • •
    Transparency over marketing: We show our sources, document our methods, and admit our limitations. No hype, no "AI-powered" buzzwords.
  • •
    Agents and builders first: Clean MCP and REST access, honest documentation, and responses designed to be cited — every fact carries its source.
  • •
    Accessibility matters: Financial data shouldn't be enterprise-gated. A fully automated pipeline is what lets us keep a real free tier — self-serve, no sales call.
