AI API Key Setup
PII Firewall routes your messages through your own AI API keys — this means your conversations never go through a shared account, and you have full control over model access and billing.
Why Your Own API Key?
| Benefit | Details |
|---|---|
| Privacy | Your API key = your account. No shared usage logs. |

| Billing control | AI usage billed directly to your account |
| No lock-in | Switch or revoke keys at any time |
