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.

What Financial Data API gives you

Bi-temporal time model

Every observation records both the period it describes and the moment it became known, so backtests are free of lookahead by construction.

Per-row provenance

Walk from any value to the named source, source URL, raw payload reference, and ingestion run that produced it.

One response envelope

Every endpoint returns data, meta, and a stable requestId. Write your parsing once.
