Notes

  • To authenticate, you’ll need a Tako API key. It’s best practice to store it as an environment variable to avoid hardcoding sensitive credentials in your code.
  • This endpoint executes a Tako Knowledge Search using a natural language query. Tako parses and interprets the query, and then assembles knowledge cards on the fly in response.
  • If the query requests multiple series of data (i.e. “Tesla Stock Price vs Net Income”), Tako will adjust the knowlkedge cards so it matches the user’s intent. This may necessitate using both a left and right y-axis to visualize data of far different dimensions/magnitudes, applying aggregations (e.g. percent change since start y-axis when there are series with distinct unit types), or other transformations.
