# Discover served forecast variables and targets

`GET /api/v1/grid/forecast-capabilities`

## Request

- Base URL: `https://askthegrid.com`
- URL: `https://askthegrid.com/api/v1/grid/forecast-capabilities`
- Auth: HTTP bearer

Capabilities from the serving registry: source and model identity, market, variable, target kinds and examples, native resolution, maximum horizon, quantiles, vintage modes and distribution representation. Listed capabilities describe published serving sources; trained experiments are not availability claims. Distributions are marginal per interval, not joint scenarios.
