# API Overview

The Macro by Mark API is organized into these domains:

| Domain                   | Description                                                                                                                                                               |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Indicators**           | The core data layer. Search, browse, and retrieve curated macroeconomic time series with metadata, observations, revisions, and export bundles.                           |
| **Discovery**            | Explore the raw provider catalog of 2M+ series. Find series that haven't been curated yet and request their addition.                                                     |
| **Forecasting**          | Run statistical forecasts (ARIMA, ETS, VAR) on any registered indicator. Export results as CSV or JSON.                                                                   |
| **Labs**                 | Econometric tooling: stationarity tests (ADF, KPSS, PP), series diagnostics, and more coming soon.                                                                        |
| **News & Calendar**      | Macroeconomic news feed and the release calendar for upcoming data publications.                                                                                          |
| **Provider Passthrough** | Direct access to underlying provider APIs (FRED, BLS, BEA, Census, Treasury, EIA, market data). Useful for advanced queries not yet abstracted into the Indicators layer. |
| **Account**              | Manage your profile, preferences, workspace, watchlist, dashboards, and notifications.                                                                                    |
| **Billing**              | Create Stripe checkout sessions and access the customer billing portal.                                                                                                   |
