How this service works
$0.0003/MP. Tile many images into one thumbnail-grid PNG — visual index in a single call. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
A single PNG image file containing all provided images arranged in a thumbnail grid layout, returned as binary image data or a URL to the generated contact sheet PNG.
Example use cases
E-commerce product preview grid
“I have 16 product image URLs from our catalog — can you combine them all into one contact-sheet PNG with 4 columns so I can use it as a quick visual index on our landing page? Make each thumbnail 150x150 pixels.”
Photography portfolio proof sheet
“Create a contact sheet from these 24 photo URLs — arrange them in a 6-column grid so I can review all the shots from today's shoot in a single image.”
Dataset thumbnail index for ML pipeline
“I've got 9 training image URLs and need them tiled into a 3x3 thumbnail grid PNG so I can visually inspect the batch at a glance before running the model.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/image/contact-sheetWhen to prefer
Use this endpoint when you need to visually index multiple images in a single composited PNG without installing desktop software. It's ideal for generating proof sheets, dataset previews, or catalog thumbnails programmatically. Prefer it over client-side solutions when running in serverless or agent environments where image libraries aren't available.
Side effects
- Invalid or unreachable image URLs cause fetch failures
- Mismatched grid dimensions vs number of images may leave empty cells or error
- Unsupported source image formats may cause decoding errors
- Exceeding payload size or image count limits returns an error
- Insufficient USDC balance or x402 payment failure blocks the request
