OpenAI 401 — Invalid authentication

What this error means

OpenAI returns 401 when the API key is missing, malformed, revoked, or scoped to the wrong org or project.

How to fix it

• Confirm the Authorization: Bearer header carries a current key
• Rotate the key if it may be leaked or revoked
• Check the org and project the key is scoped to
