How this service works
Generate image using bytedance/seedream/v4/text-to-image
Output
Returns a JSON object with a unique jobId, a human-readable message containing a status tracking URL, a direct statusUrl to poll for the completed image, an ISO 8601 timestamp, and an HTTP status code. The actual image is retrieved asynchronously by polling the statusUrl.
Example use cases
Example prompt
“Generate an image of a futuristic neon-lit Tokyo street at night with rain reflections, in landscape 16:9 format, using SeedDream v4, with prompt enhancement set to standard mode and safety checker enabled.”
Technical details
Endpoint
POSThttps://x402.dopamint.ai/api/ai/generations/images/seedreamWhen to prefer
Choose this endpoint when you need high-quality text-to-image generation powered specifically by ByteDance's SeedDream v4 model, and you are operating in an x402 micropayment context with USDC. Prefer it when you need async job-based generation with status polling, support for multi-image batch generation, flexible aspect ratios including auto 2K/4K, and optional prompt enhancement. Best suited for agents with crypto payment capability and tolerance for async retrieval patterns.
Side effects
- Missing required 'prompt' field returns a 400 validation error
- Image size below 921600 total pixels is auto-scaled up, potentially altering intended dimensions
- Payment of $5 USDC not provided or rejected via x402 protocol results in a 402 Payment Required error
- Invalid image_size string not matching enum values causes a schema validation error
- Job may time out or fail on the backend, requiring polling statusUrl for error status
- Safety checker rejection if content violates policy when enable_safety_checker is true
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| seed | integer | Random seed to control the stochasticity of image generation. |
| promptrequired | string | The text prompt used to generate the image |
| sync_mode | boolean | If `True`, the media will be returned as a data URI and the output data won't be available in the request history. |
| image_size | ImageSize | "square_hd" | "square" | "portrait_4_3" | "portrait_16_9" | "landscape_4_3" | "landscape_16_9" | "auto" | "auto_2K" | "auto_4K" | The size of the generated image. The minimum total image area is 921600 pixels. Failing this, the image size will be adjusted to by scaling it up, while maintaining the aspect ratio. |
| max_images | integer | If set to a number greater than one, enables multi-image generation. The model will potentially return up to `max_images` images every generation, and in total, `num_images` generations will be carried out. In total, the number of images generated will be between `num_images` and `max_images*num_images`. |
| num_images | integer | Number of separate model generations to be run with the prompt. |
| enhance_prompt_mode | "standard" | "fast" | The mode to use for enhancing prompt enhancement. Standard mode provides higher quality results but takes longer to generate. Fast mode provides average quality results but takes less time to generate. |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. |
