With BYOK (Pro or Studio), your actual API cost depends on how many tracks you generate per month. Here's what you'd pay Anthropic directly at current Sonnet 4.6 pricing. Starter users have a fixed cost of €6.99/month regardless of volume.
Estimate based on ~€0.0465 per generation (Sonnet 4.6 avg: 500 input + 3000 output tokens). Actual cost varies by prompt complexity. Anthropic bills in USD; EUR conversion approximate. Starter Library Mode costs exactly €6.99/month for up to 300 prompts — no API cost at all.
Go to console.anthropic.com and sign up with your email. The account is free to create — you only pay for what you use.
In the Console: API Keys → Create Key. Give it a name (e.g. "AMPA"). Your key starts with sk-ant-. Copy it immediately — Anthropic shows it only once.
In the app, find the 🔑 API Key bar just below the module tabs. Paste your key and press SAVE. The badge turns green: ✅ BYOK Active. Done.
Go to Billing in the Console and add a payment method. You can start with $5 — at Sonnet 4.6 pricing that's roughly 100 generations. Anthropic offers auto-recharge above a threshold so you never run dry mid-session.
Start with Starter if you want zero setup and a predictable flat cost. Go Pro or Studio if you want full AI access and unlimited generations.
