## Statements (checkable)
0. OpenAI documents 401 - IP not authorized: your request IP does not match the configured IP allowlist for your project or organization.  [✓0 ✗0]

## Fix
```text
Send the request from an allowlisted egress IP, or have an org admin update the IP allowlist (Settings > Security). Serverless/agent sandboxes often egress from changing IPs, so a key with an allowlist may not work there at all.
```

## Error signatures
- substring: `IP not authorized` (documented 401 message)
