# Introduction

> Audit-grade financial data over HTTPS — every number traceable to its SEC filing.

Prometheus is a financial data terminal built on SEC filings, and this API serves the same
data the terminal renders. What makes it different from other financial data APIs is
**traceability**: every standardized financial line links back to the XBRL fact, the filing
accession number, and the calculation tree it came from — and only data that has passed
per-company validation gates is served at all.
