With Nodaro connected to Claude, ChatGPT or Cursor, ask in plain words, or have the assistant call the tool: “Use Kling 4.0 Keyframes to make: A paper boat drifts down a rain-soaked street at dusk, slow dolly in”

curl -s -X POST https://app.nodaro.ai/v1/text-to-video \  -H "Authorization: Bearer $NODARO_API_KEY" \  -H "Content-Type: application/json" \  -d '{        "prompt": "A paper boat drifts down a rain-soaked street at dusk, slow dolly in",        "provider": "kling-4-keyframes",        "duration": 3      }'

Prompt tips

• kling-4: text only, or up to 10 images, 5 videos (2-30s), 7 characters and 3 voices (15 in all). Name each: @image_1, @video_1, a character's @Name, a voice clip @audio_1.
• kling-4-keyframes: start frame, up to 8 in-between frames (Image References, in order), end frame — @first_frame, @keyframe_1 …, @last_frame. 3s takes 4 frames in all, 9s or longer 10.
• 3-30s (default 5), 720p (default) / 1080p, native audio always on. A reference video lends its camera moves and pacing; keep-original-sound keeps its own audio.
• Prompt cap 8,000 chars. Aspect auto / 16:9 / 9:16 / 1:1 / 21:9 — Keyframes follows the start frame's shape once a frame is attached.
