AlphaVantageTool

AlphaVantageTool is a simple component that lets you pull real‑time or historical financial data from the Alpha Vantage service. You can ask for different kinds of information—such as ticker details, time series, or technical indicators—by choosing the appropriate option in the dropdown.

How it Works

When you run the component, it sends a request to Alpha Vantage using the API key you provided. The component then receives the data back from Alpha Vantage and returns it in a format that can be used by other parts of your workflow. Because the request is made over the internet, the component needs a valid Alpha Vantage API key, which you store securely in Nappai’s credential system.

Important:

  1. First, add an Alpha Vantage API credential in the Nappai credentials section.
  2. In the component, select that credential from the “Credential” field.
  3. The component will then use the stored API key to talk to Alpha Vantage.

Inputs

Input Fields

  • Information to request: Choose the type of data you want from Alpha Vantage (e.g., ticker info, time series, etc.).
  • Input: Enter the value that the API needs for the chosen request, such as a stock ticker symbol (e.g., AAPL) or a specific date.

Outputs

  • Data: The raw information returned from Alpha Vantage, wrapped in a Data object. This can be displayed, logged, or passed to other components.
  • Tool: A reusable Tool object that can be used by other parts of the system to perform the same Alpha Vantage request again.

Usage Example

  1. Configure the credential: In Nappai’s credentials panel, add an Alpha Vantage API key and give it a name.
  2. Add the component to your dashboard.
  3. Select the credential in the component’s “Credential” field.
  4. Set “Information to request” to “Ticker Info”.
  5. Enter “Input” as AAPL.
  6. Run the component.
  7. The Data output will contain the ticker information for Apple Inc., which you can then use in charts, reports, or further calculations.
  • AlphaVantageStockPriceComponent – Retrieves the latest stock price for a given ticker.
  • FinancialDataAnalyzer – Performs analysis on financial data fetched from various sources, including Alpha Vantage.
  • DataExporter – Exports data from the workflow to CSV, Excel, or a database.

Tips and Best Practices

  • Keep your API key private: Never expose it in public code or share it openly.
  • Respect rate limits: Alpha Vantage limits the number of requests per minute; add pauses or batch requests if you need many symbols.
  • Validate input: Ensure the ticker symbol or date format is correct to avoid errors.
  • Use the Tool output: If you need to reuse the same request in multiple places, use the Tool output instead of re‑configuring the component each time.

Security Considerations

  • The API key is stored in Nappai’s secure credential store, not in the component’s configuration.
  • Only users with permission to view credentials can see the key.
  • The component transmits data over HTTPS, so the connection to Alpha Vantage is encrypted.
