# Overview

> Point-in-time macroeconomic, rates, calendar, fundamentals, and derived-analytics data from official sources, served as predictable JSON for developers and AI agents.

Financial Data API is a point-in-time data API for macroeconomics and global markets. Every value carries the period it describes, the moment it became known, a freshness label, and a full provenance chain back to its official source, so the same query returns the same answer today, next quarter, and inside a five-year backtest.

It is built for two audiences: developers shipping research tools, dashboards, and trading systems that cannot tolerate silent data drift, and AI agents that need a self-describing, redistribution-safe surface they can discover and call without bespoke glue.
