Building with Claude API

Let's get you set up with Claude API access.

**Steps:** 1. Go to [console.anthropic.com](https://console.anthropic.com) 2. Sign up or log in 3. Add a payment method (required, but you get free credits) 4. Go to API Keys section 5. Create a new key 6. Copy it immediately (you won't see it again!)

**Pricing (as of 2024):** - Claude 3.5 Sonnet: $3/$15 per million tokens (input/output) - Claude 3 Opus: $15/$75 per million tokens - Claude 3 Haiku: $0.25/$1.25 per million tokens

**For learning:** Start with Haiku or Sonnet — very affordable for experiments.
