FAQ
Do I need to provide my own Claude API key?
Yes, you'll need an Anthropic API key. I can guide you through the setup—it takes 5 minutes and starts with free credits. This keeps costs transparent and gives you full control.
Can you integrate this with my existing website or app?
Yes! I can build standalone agents or integrate them into your existing Next.js, React, Python, or other applications. Just let me know your tech stack and I'll confirm compatibility.
What's the difference between Sonnet, Opus, and Haiku?
Sonnet (balanced—best for most use cases), Opus (smartest—complex reasoning), Haiku (fastest/cheapest—simple tasks). I'll recommend the best model based on your specific needs and budget.
Will I own the code after delivery?
Yes, you get full ownership of all code and documentation. No licensing fees, no restrictions. I can also provide deployment support if you need help launching.
Do you work with other AI APIs like OpenAI or Gemini?
Yes, but Claude API is my specialty. I can work with OpenAI GPT-4, Gemini, or other APIs—just message me first so I can confirm the scope and timeline for your project.
