Exist

Fetch the connected Exist account's profile: username, name, avatar, timezone, local time and unit preferences.

List Exist's built-in attribute templates — the catalogue of trackable attributes an account can adopt, with their group and value type.

List the account's own attributes (no values), including which service provides each one.

List the account's attributes together with their most recent date/value pairs — the fastest way to see how recent days went.

Page back through one attribute's historical values, newest first.

List the attributes this connection currently owns and may therefore write to.

List weekly average values per attribute, with an overall average and one per weekday.

List the account's insights — Exist's generated observations about a day, week or month, as text and HTML.

List the correlations Exist generated in the last week, with coefficient, p-value and a plain-language description.

Fetch the correlation between two named attributes (order does not matter); 404 when Exist has not generated one.

Take ownership of attributes so this connection can write their values. Pass `template` for a built-in attribute or `name` for an existing one. Only manually tracked and custom attributes are within this connection's granted write scopes.

Give up ownership of attributes. Their values stay in Exist, but this connection can no longer write them.

Create custom attributes and acquire them in one call. Exist generates each attribute's `name` from its label, so read it back from the response.

Overwrite the value of owned attributes on specific dates. Each value REPLACES the day's total; a non-null value cannot be set back to null.

Add to the stored value of owned numeric attributes. Date defaults to today. String, scale and time-of-day attributes cannot be incremented.
