Authorization changed during the request
Your key's entitlements or a source's availability changed while the response was being built, so it was stopped rather than mixing two sets of permissions.
"type": "https://ohlc.io/problems/authorization-changed"
Why it happens
- A plan change, key scope edit or key rotation took effect mid-request.
- Licensing or source availability for the data changed during delivery.
How to fix it
- Retry the request; it will run under the current entitlements.
- If you were paging, restart from the first page.
