Error Handling
Token expired: If tools return a 401 error, the XREPLY_TOKEN has expired (tokens last 30 days). Ask the user to get a fresh token from XreplyAI Settings and update it in their OpenClaw config.
Quota exhausted: If generation returns a quota error (e.g. "Daily generation quota exhausted"), call xreply_billing_status to check limits and inform the user. Quota resets at midnight.
Quota insufficient for batch: If xreply_posts_generate_batch returns quota_insufficient: true, reduce count to the available value shown in the response, or ask the user to confirm.
Schedule out of range: If scheduling returns a validation error, the requested time exceeds the plan's scheduling horizon. Call xreply_billing_status to check max_schedule_days and suggest an earlier time.
Cannot edit/delete: Posts with status processing or posted cannot be edited or deleted. Call xreply_posts_list to check the current status.
Viral library requires Pro: If xreply_viral_library or xreply_rules_list returns a 403, inform the user these features require a Pro or BYOK subscription.
