Choose this endpoint when you need to programmatically composite, watermark, or overlay one image on top of another with control over position and blend/opacity. Ideal for automated branding pipelines, batch watermarking workflows, or any agent task requiring image layering at a low per-megapixel cost with micropayment x402 billing.
Side effects
- Invalid or inaccessible image URL returns an error
- Unsupported image format causes processing failure
