Key API Endpoints
POST /v1/jobs/generate— Submit a text-to-image or image-to-image generation job. Accepts parameters such asmodel_id,prompt,negative_prompt,width,height,steps,cfg_scale,sampler, and optionallorareferences.GET /v1/jobs/{job_id}— Poll the status of a submitted job and retrieve output image URLs upon completion.
