Tool to acquire ownership of attributes for the authenticated user. Allows your service to write data to these attributes. Use when you need to create or take ownership of attributes before writing data. Acquiring a templated attribute the user doesn't have yet will create this attribute and give you ownership.

Tool to retrieve attributes with their current values for the authenticated user. Use when you need both attribute metadata and their historical values. Results are limited to your read scopes.

Tool to retrieve a paged list of supported attribute templates. Use when you need to browse available templates before creating or updating data.

Tool to retrieve the most recent average values for each tracked attribute, with one set per week. Returns overall weekly averages plus daily breakdowns (Monday-Sunday). Use include_historical flag to retrieve historical average records.

Retrieve a paginated list of correlations discovered between tracked attributes in the last week. Correlations reveal statistical relationships between different metrics (e.g., sleep duration vs mood). Filter by relationship strength, confidence level (statistical significance), or specific attributes. Returns correlation coefficients, p-values, and human-readable descriptions.

Tool to retrieve automatically-generated insights about patterns in tracked data for the authenticated user. Insights are observations about correlations, trends, and anomalies (e.g., "You walked more on days you slept well"). Use when analyzing user behavior patterns or displaying personalized feedback.

Tool to retrieve attributes owned by your service for the authenticated user. Use when you need to limit data updates to only the attributes your service controls.

Tool to retrieve a paged list of the user's attributes without values. Use when you need metadata on available attributes for filtering or selection. Omitting `groups` and `attributes` filters returns the full attribute catalog; use those filters to narrow results and avoid oversized responses.

Tool to retrieve the authenticated user's profile details and preferences. Use after authentication to inspect account settings and status. OAuth scopes granted during authentication determine which fields are returned; missing fields indicate insufficient scopes. Response includes a timezone field; use it when interpreting any date-based attributes.

Tool to increment attribute values by a delta amount rather than setting totals. Use for counters and cumulative data. Does not work with string, scale, or time of day attributes.

Constructs an OAuth2 authorization URL for Exist.io. This tool generates the URL that users must visit in their browser to grant permissions to your application. After user consent, Exist redirects back to your redirect_uri with an authorization code that can be exchanged for an access token. This action does not make an API call - it only builds the authorization URL.

Tool to release ownership of attributes for the authenticated user. Use when your service will stop providing data for an attribute or becomes inactive.
