Turn an approved image brief into a controlled next PNG when an agent needs to iterate wit
Turn an approved image brief into a controlled next PNG when an agent needs to iterate without losing the prompt setup. Send a text prompt with optional width, height, tier, model, seed, and negative prompt; receive a hosted image URL plus the resolved model, final dimensions, prompt, seed, and timing. Venice is primary, with automatic fal.ai Z-Image Turbo failover after a definitive provider error. Keep the canvas, tier, and seed from an approved response fixed, then change one prompt detail for the next paid image pass. Choose fast for drafts, creative for campaign artwork, anime for illustration, or sd35 for Stable Diffusion-style output. Use it as an AI image generator API, repeatable text-to-image API, prompt-to-PNG API, or hosted image-production endpoint.
