Macro — ink drop in water
Extreme close-up of a single drop of dark blue ink falling into a glass of perfectly still water. The moment of impact creates a small crown splash, then billowing clouds of ink expand outward in fractal tendrils. The ink forms mushroom-cloud shapes and delicate filaments as it disperses through the water. Shot against a bright white backlight that makes the ink patterns appear as dark silhouettes with translucent edges where the concentration thins. Ultra slow motion capturing every micro-turbulence. The camera remains perfectly static — all motion comes from the ink itself.

Using this seedance-2.0-fast prompt
How do I copy this prompt safely?
Use the copy button beside the full prompt block. It copies only the prompt text, not surrounding page labels, so you can paste it into an agent instruction, a JSON request body, or your own prompt library.
Why does the detail page show parameters?
Some prompts were collected with saved generation settings such as aspect ratio, duration, or voice controls. When parameters exist, the page lists them separately so you can reuse the prompt text and the structured settings together.
Which endpoint should I call?
Use the endpoint path shown in the API code block. The path is generated from the prompt's RunAPI service and endpoint name, then rendered as the public API URL used by curl and SDK examples.
Can I use this prompt in an agent instead of code?
Yes. Pick Claude Code, Codex, Cursor, or Windsurf in the tab switcher, install the RunAPI MCP Server, and paste the generated instruction. The instruction includes the full prompt text.
