Use this tool with your agent
Give this to your agent
Use my connected Agentik MCP server. I want to use the tool fal/luma-ray-3-2-text-to-video (Luma Ray 3.2, text to video). Call inspect_tool with {"tool_id": "fal/luma-ray-3-2-text-to-video"} first and tell me the price before anything runs. Ask me for the inputs it needs; never invent values, IDs or file URLs. When I confirm, call run_tool with tool_id "fal/luma-ray-3-2-text-to-video" and my inputs, follow it with get_run if it is still running, and give me the result and the price Agentik reports. If the tool is unavailable, say so and use discover_tools to propose an alternative.Show the prompt
Paste it into Claude, ChatGPT or Codex: your agent takes it from there, and shows the price before it runs.
