What you need
- An Anthropic account at console.anthropic.com.
- A live API key with budget set.
- Pro plan or higher on Niyra.
Steps
- console.anthropic.com → Settings → API Keys → Create Key.
- Name it
niyra-byok(anything works, but you'll thank yourself when rotating). - Copy the key (only shown once).
- Niyra: Settings → BYOK → Anthropic → paste key → Save.
- Hit Test. You should get a green check within 2 seconds.
What it unlocks
- Apex mode (Opus 4 / Fable 5) per conversation.
- All Sonnet calls run on your account when BYOK is active for the convo.
- Your Niyra credits stop ticking for LLM in those convos.
Rotation
When you rotate:
- Create new key in console.
- Replace in Niyra's BYOK panel.
- Wait ~60s for in-flight requests to drain.
- Disable / delete old key in console.
Spending caps
Set a monthly cap in the Anthropic console. Niyra respects it — when you're near the cap, the conversation pauses with a clear message instead of silently failing.
