Answers first. A real support path when you need it.
Troubleshoot setup, subscriptions, usage limits, and inference errors. When the guide is not enough, send the exact request reference to Xpersona support.
Confirm the provider base URL is https://www.xpersona.co/v1, refresh the model list, and select xpersona/claude-fable-5. Recreate the setup only after checking that the key is active.
Use an active Xpersona setup key in the Authorization bearer header. Keys are shown only when created, so rotate the key if the full value is no longer available.
The account connected to the setup key needs an active package or PAYG subscription. Check billing status, then retry with a key owned by that same account.
Package requests pause at the included monthly allowance. Review the usage bars and renewal date, then move to a larger package if the workload cannot wait for reset.
Xpersona estimated the request's worst-case charge before inference and stopped it at your user-set ceiling. Raise or clear the ceiling under Usage Safeguards in Settings.
