+# Billing Not Active — diagnostic transcript
+
+## Symptom
+ALL 67 accounts under one workspace return identical error:
+```
+HTTP 429 Too Many Requests
+{"error":{"message":"Your account is not active, please check your billing details on our website.","type":"billing_not_active","code":"billing_not_active"}}
+```
+
+## Root cause
+Workspace `rebeccaberger717419_outlook.com` (id: `708980e0-b4d9-4ceb-89e0-0b196d2f39fc`) has no payment method. All 67 accounts share the same `chatgpt_account_id` → billing is workspace-level → one missing card blocks everything.
+
+## Diagnostic pattern
+Test 8 accounts spread across the full range [0, 10, 20, 30, 40, 50, 60, 66]. If ALL return billing_not_active → workspace issue, not individual account issue.
+
+## Refresh token state
+Refresh tokens are one-time-use. After first refresh, they return:
+```
+HTTP 401
+{"error":{"message":"Your refresh token has already been used to generate a new access token. Please try signing in again.","code":"refresh_token_reused"}}
+```
+
+## Access token format
+Tokens in `verify-jwt` batch are full 1700+ char JWTs. `read_file` truncates display with `...` but `len(token)` in Python confirms full length. Tokens authenticate successfully (200 on /v1/models, 401/429 on chat).
+
+## Image generation
+`gpt-image-2` returns 401 with missing scopes — requires specific role/permission in workspace:
+```
+HTTP 401
+{"error":{"message":"You have insufficient permissions for this operation. Missing scopes: api.model.images.request..."}}
+```
