Quick start
task_id after submission and poll GET /v1/tasks/{task_id}. Download files from result.images[].url[] on success. Continue polling the original task after a timeout; do not submit a duplicate.
Parameters
Reference editing
GIF
Billing
Both variants use the same fixed per-image prices:
Quality, planning effort and references have no separate surcharge. The reservation and successful settlement use the same fixed price. Existing tasks retain their frozen tariff after a price update. Check final
billing_status and refund records for failed tasks.
Resolution and actual pixels
4k names the supplier’s resolution tier, rather than a promise of a 4096-pixel edge for every aspect ratio:
For text generation, auto uses 1:1. For editing, auto matches the closest reference aspect ratio; it does not preserve exact input dimensions. At 2K/4K use PNG/JPEG/WebP references, not GIF/BMP.
Examples
These images were generated by their named Economy variants usingresolution: "4k" and aspect_ratio: "1:1". Both original files are 2880×2880.
