Not all providers support all three capability modes. Check the capabilities array in GET /providers/{slug} to know which modes are available for a given provider.

Provider capabilities

• hierarchical — Browse the provider’s catalog as a tree of categories. Use GET /providers/{slug}/browse to navigate.
• search — Search across the provider’s catalog by keyword. Use GET /providers/{slug}/search?q=your+query.
• direct — Fetch a specific series if you already know its ID. Use GET /providers/{slug}/series/{seriesId}.

API endpoints

The base URL for all provider operations is https://api.alphacast.io.

Method	Endpoint	Description
GET	/providers	List all available providers
GET	/providers/{slug}	Get a single provider’s details and capabilities
GET	/providers/{slug}/browse	Browse the provider’s catalog hierarchically

Listing all providers

curl https://api.alphacast.io/providers \
  -u YOUR_API_KEY:

[
  {
    "slug": "fred",
    "name": "FRED Economic Data",
    "provider": "Federal Reserve Bank of St. Louis",
    "description": "Hundreds of thousands of economic time series from dozens of national, international, public, and private sources.",
    "capabilities": ["search", "hierarchical", "direct"],
    "license": "Public Domain (mostly)"
  }
]

Browsing hierarchically

For providers with the hierarchical capability, you can navigate the catalog tree using the path parameter. Start at the root and drill down by appending path segments.

# Browse the root of the FRED catalog
curl "https://api.alphacast.io/providers/fred/browse" \
  -u YOUR_API_KEY:

# Browse a subcategory
curl "https://api.alphacast.io/providers/fred/browse?path=National%20Accounts" \
  -u YOUR_API_KEY:

Searching a provider

curl "https://api.alphacast.io/providers/fred/search?q=unemployment+rate" \
  -u YOUR_API_KEY:

Fetching a FRED series

Once you know a series ID, fetch a preview (last 24 data points) with a GET request, or the full dataset with a POST.

Preview (last 24 points)

curl "https://api.alphacast.io/providers/fred/series/UNRATE" \
  -u YOUR_API_KEY:

curl -X POST "https://api.alphacast.io/providers/fred/series/UNRATE/data" \
  -u YOUR_API_KEY: \
  -H "Content-Type: application/json" \
  -d '{"params": {}}'

{
  "series_id": "UNRATE",
  "label": "Unemployment Rate",
  "metadata": {
    "frequency": "Monthly",
    "units": "Percent",
    "seasonal_adjustment": "Seasonally Adjusted"
  },
  "data": [
    { "date": "2024-10-01", "value": 4.1 },
    { "date": "2024-11-01", "value": 4.2 }
  ],
  "is_preview": false
}

Storing a provider API key

Some providers — including FRED and BLS — require their own API key to access higher rate limits or restricted data. You can store your key in Alphacast so it is used automatically whenever you fetch from that provider.

curl -X PUT https://api.alphacast.io/user-keys/fred \
  -u YOUR_API_KEY: \
  -H "Content-Type: application/json" \
  -d '{"api_key": "YOUR_FRED_API_KEY"}'

{ "slug": "fred", "has_key": true }

To remove a stored key, send null or an empty string as the api_key value.

To get a free FRED API key, register at https://fred.stlouisfed.org/docs/api/api_key.html. Without a key, FRED requests may be rate-limited.
