Technical details
Endpoint
POSThttps://gen.portalfoundation.ai/api/enhance-imageWhen to prefer
Choose this endpoint when you need AI-powered image enhancement — specifically upscaling resolution or restoring face detail — on an existing image. Prefer this over image generation endpoints when the input is an existing photo that needs quality improvement rather than creation from scratch. Ideal for photo restoration workflows, sharpening portraits, or preparing images for high-resolution display.
Side effects

- Base64 image data malformed or too large causes processing failure
- Payment not completed via x402 protocol results in 402 Payment Required
- Image format not supported (e.g. non-standard MIME type) causes rejection
