Supported Tools
increment_attribute_values
Increment Attribute Values
Add incremental (delta) values to owned attributes instead of setting absolute totals. Useful for event-driven tracking where Exist tallies the running total. If no date is provided, defaults to today.
get_attributes
Get Attributes
Retrieve the user's tracked attributes from Exist, optionally with their recent daily values. Filter by group (activity, sleep, mood, etc.) or specific attribute names. When values are included, up to 31 days of historical data can be fetched.
update_attribute_values
Update Attribute Values
Set absolute values for owned attributes on specific dates. Overwrites any previous value for the given date. Supports batch updates of up to 35 values in a single call. You must own the attribute before updating its values.
get_attribute_values
Get Attribute Values
Retrieve the historical daily values for a specific attribute. Returns a paginated list of date/value pairs, allowing you to query extensive history for a single attribute with date range filtering.
get_correlations
Get Correlations
Retrieve correlations between tracked attributes. Correlations describe relationships between two data points (e.g., "You have a better day when you walk more"). Generated weekly from up to a year of data. Can retrieve all correlations or look up a specific pair.
get_user_profile
Get User Profile
Retrieve the authenticated user's Exist profile including username, timezone, and measurement unit preferences (imperial vs metric for distance, weight, energy, liquid, temperature).
manage_attribute_ownership
Manage Attribute Ownership
Acquire or release ownership of attributes. You must own an attribute before writing data to it. Acquiring a templated attribute the user doesn't have yet will create it automatically. Releasing an attribute passes ownership to another connected service or deactivates it.
get_insights
Get Insights
Retrieve automatically generated insights about the user's data. Insights are events found within the user's tracked data, such as "Yesterday was your highest steps value in 30 days" or weekly/monthly summaries. Results are limited to your read scopes.
get_averages
Get Averages
Retrieve the most recent weekly average values for tracked attributes, computed from the last 60 days of data, including an overall average and per-day-of-week breakdowns (Monday through Sunday). Optionally retrieve historical averages to see trends over time.
create_attribute
Create Attribute
Create new attributes in Exist, either from existing templates or as fully custom attributes. Custom attributes require a label, group, and value type. The service automatically gets ownership of created attributes.
get_attribute_templates
Get Attribute Templates
Discover supported attribute template names, labels, groups, priorities, and value types before creating or acquiring attributes.
