DESCRIPTION

Call Venice's Kimi K3 model through a flat-price x402 endpoint with no Venice account or API key. Send a prompt plus an optional system message, temperature, and max_tokens. This endpoint invokes the exact kimi-k3 upstream model, caps prompts at 8,000 characters and output at 768 tokens, and returns the model name and token usage when supplied by Venice. Use it for Kimi K3 chat, bounded agent reasoning, coding questions, extraction, or a pay-per-call Kimi API.
