Endpoint: /v1/videosUse the same request contract in the Playground and API, then handle validation, balance, task state, and output retrieval explicitly.
Validate the model, prompt, references, and output settings.
POST the request and retain the returned task ID.
Poll task status or process the configured callback.
Fetch the generated file from the content endpoint and store it before expiry.
Reject unsupported sizes, durations, ratios, formats, or reference counts before submitting.
Handle invalid keys, insufficient balance, rate limits, and account-group pricing separately.
Surface the rejected prompt or asset clearly so the user can replace only the failing input.
Keep the task ID, use bounded retries, and never treat a timeout as a successful generation.

Generated with Seedance 2.0
Creative direction: An original hand-drawn adult woman in a yellow raincoat waits on a rain-soaked railway platform beside a red umbrella. She opens and reads a white letter; the camera pushes from the platform view into her worried close-up and holds on her reaction. Visual treatment: Rainy anime drama with cool platform light and yellow-red costume accents. Shot sequence: 1. Establish the yellow raincoat and red umbrella on the wet platform.; 2. Move closer as the woman opens the white letter and lowers her gaze.; 3. Hold her worried close-up with the letter still below her eyeline. Continuity: Keep the character's face, clothing and key prop consistent; preserve screen direction across cuts. Exclude: extra people or props, text, logos and watermarks.

Creative direction: A coral-orange insulated bottle stands on a wet dark-teal studio surface beside a clear glass and a few ice cubes. One adult hand unscrews the cap and pours cold water over the ice, then sets the bottle beside the filled glass. End on a clean product hero frame with both bottle and glass visible. Visual treatment: Photoreal product commercial. A soft overhead key reveals the matte coral finish; a cool cyan edge light picks out condensation and the restrained floor reflection. Shot sequence: 1. Open on condensation and ice in a tight detail shot; 2. Cut to a steady three-quarter view for the cap opening and single pour; 3. Settle on the bottle and chilled glass together, with the bottle silhouette unobstructed Continuity: Keep the product silhouette, cap or hinge, materials and prop positions stable; hold the final hero frame. Exclude: extra people or props, text, logos and watermarks.

Track his approach as dawn light crosses the vintage telescope.; 3. Settle with the telescope and figure against the cool dome interior. Continuity: Maintain scene geography, subject scale and motivated light direction throughout the camera move. Exclude: extra people or props, text, logos and watermarks.

Creative direction: An orange-suited astronaut walks through a dark hangar toward a massive grounded machine. The camera follows from behind as work lights flicker on and the machine powers up with blue-white light, ending on the figure beneath its scale. Visual treatment: Science-fiction game cinematic with orange fabric, dark metal and blue-white practical lights. Shot sequence: 1. Follow the orange-suited astronaut from behind into the hangar.; 2. Continue forward as work lights illuminate the grounded machine.; 3. Hold the small figure beneath the machine as blue-white power light stabilizes. Continuity: Maintain character design, equipment geometry and travel direction from first to final frame. Exclude: extra people or props, text, logos and watermarks.
