Why use Ceven?

  1. AI native Exist integration

    • Describe the outcome and Ceven picks the right Exist calls, fills the parameters, and checks the result.
    • Structured, agent friendly tool schemas so each call runs reliably instead of by guesswork.
    • Rich coverage for reading, writing, and querying your Exist data, across all 12 of its actions.

  2. Managed auth

    • Built in OAuth with automatic token refresh and rotation.
    • One place to manage, scope, and revoke Exist access.
    • Per user and per environment credentials instead of shared keys.

  3. Agent optimized design

    • Actions are tuned from real success and error rates so reliability climbs over time.
    • Full execution logs so you always know what ran in Exist, when, and on whose behalf.
    • The agent pauses and asks when Exist is unclear instead of plowing ahead.

  4. Enterprise grade security

    • Fine grained access so you control which agents and people can reach Exist.
    • Least privilege by default, read scopes first and only the writes a workflow needs.
    • A full audit trail of every Exist action to support review and sign off.

Frequently asked questions

Ceven respects all privacy controls set within your Exist account. We use OAuth2 to request specific scopes of access, meaning you only share the data categories you approve during the connection process. All data pulled from Exist into Ceven is encrypted in transit and at rest. We do not sell your biometric or behavioral data to third parties. You can view exactly what permissions are granted in your Exist settings and revoke the Ceven token at any time. Once revoked, Ceven loses all access to your data streams immediately and cannot perform any further reads or writes to your account.
No. Correlations in Exist are generated by the internal Exist analytics engine based on the data points it collects over time. Ceven cannot force a correlation to exist or manually create one because these are calculated results of statistical analysis. However, Ceven can read these correlations and trigger workflows based on them. For example, if Exist finds a strong correlation between your coffee intake and poor sleep, Ceven can detect that new correlation and automatically add a reminder to your calendar to stop drinking caffeine by noon.
If a source like a Fitbit or Oura ring stops syncing to Exist, the data gap will reflect in the API responses Ceven receives. Ceven can be configured to detect these gaps by monitoring the last updated timestamp of your attributes. You can build a workflow that sends you a notification if no new sleep data has landed in Exist for forty eight hours. This ensures you know when a wearable battery has died or a third party token has expired, preventing the AI from making decisions based on stale or missing information.
Yes. Exist imposes rate limits on its API to ensure platform stability. If a workflow attempts to pull massive amounts of historical attribute data in a very short window, Exist may return a rate limit error. Ceven handles this by implementing an exponential backoff strategy, meaning the agent will automatically pause and retry the request after a short delay. For most users, this is invisible, but if you are running extremely complex analysis across years of daily data, you might notice a slight delay in the completion of the workflow.
Yes. Through the custom attribute tools, Ceven can push data into Exist that does not come from a standard integration. This is useful for tracking things like a specific medication, a new diet, or a particular work habit. You can set up a prompt in Ceven to log a custom attribute in Exist every time you complete a specific task in your project management tool. This allows Exist to find correlations between your professional output and your personal wellbeing by bringing non traditional data into the analytics engine.
Ceven operates primarily as a pass through layer for your Exist data. While we cache some data temporarily to provide context for the AI model during a session, we do not maintain a permanent parallel database of your entire biometric history. Your primary source of truth remains Exist. If you delete your data within Exist, it will no longer be available to Ceven. This architecture ensures that you maintain full ownership and control over your sensitive health information without worrying about fragmented copies across multiple platforms.
Absolutely. This is one of the strongest use cases for the integration. You can create a workflow that pulls your monthly correlation summary from Exist and pushes it into a Notion database or a Google Sheet for long term archiving. You can also send specific alerts to Slack or Discord when Exist identifies a new significant trend. By using Ceven as the bridge, you move from simply viewing your life analytics to actually operationalizing that data across the rest of your software stack.
