About this API
Dot returns a chat completion without storing the prompt. Send an OpenAI-style body such as { "model": "dot-auto", "messages": [{ "role": "user", "content": "..." }] } and pay about $0.009 in USDC on Base over x402.
The browser checks the live x402 terms before every paid call. If CORS blocks a direct request, vAPI gives you the exact vapi-network handoff.
