Tako connects your app with real-time, trusted data that’s often not readily crawlable on the internet. Developers can use Tako’s API to ground their other response sources, and ensure consistency between what’s derived from other sources and what’s displayed in Tako cards. For example, Tako can help ground Nvidia’s stock price analysis you derive from LLMs and web search with Tako’s stock price cards that feature up-to-date pricing data. Tako includes the following information in each API response that can be used to ground answers.
Data Description: A natural language description of the data and visual elements included in the card (including last data point)
Sources: A list of sources, including a description of the source
Methodology: Methodology information for data present in the card
Static Image: A link to a static image of the card

The following is an example response for a Weather Card from Tako:

Hourly and daily forecast data were sourced directly from NWS APIs through their public-facing weather.gov data services. Temperature, precipitation probability, humidity, and wind measurements reflect NOAA's standard meteorological observations and predictive models, which incorporate ground station measurements, radar, satellite imagery, and numerical weather prediction models. The temperature graph displays a 24-hour forecast with readings taken at hourly intervals. All temperatures are displayed in Fahrenheit with Celsius conversion available. Moon phase calculations are derived from NOAA astronomical data. No statistical adjustments or data transformations were applied to the raw NWS datasets. This visualization was last updated on March 14, 2025, at 8:00 PM PDT to reflect the most current forecast information available from NOAA."
