# Build with Sonic

The quickest way to get started with Sonic is by using an [integration](/integrations/overview).
If you are using the API directly, check out Cartesia's [client libraries](/tools/client-libraries) and [AI tools](/tools/ai/agent-guide).

The references section contains complete documentation for all API endpoints and best practices.
