BYOK — Anthropic setup What you need - An Anthropic account at console.anthropic.com. - A live API key with budget set. - Pro plan or higher on Niyra. Steps 1. console.anthropic.com → Settings → API Keys → Create Key. 2. Name it niyra-byok (anything works, but you'll thank yourself when rotating). 3. Copy the key (only shown once). 4. Niyra: Settings → BYOK → Anthropic → paste key → Save. 5. 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: 1. Create new key in console. 2. Replace in Niyra's BYOK panel. 3. Wait ~60s for in-flight requests to drain. 4. 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.
