How this service works
Report format, dimensions, mode, aspect ratio, transparency, and byte size of an image.
Output
Returns a structured object containing the image format (e.g. PNG, JPEG, WEBP, GIF, BMP), pixel dimensions (width × height), color mode (e.g. RGB, RGBA, grayscale), aspect ratio, a boolean indicating transparency support, and the file's byte size.
Example use cases
Pre-upload image validation pipeline
“Before I upload this image to our CMS, can you inspect https://cdn.mysite.com/hero-banner.png and confirm its format, dimensions, aspect ratio, and byte size so I know it meets our specs?”
Transparency check for design assets
“I need to know if this logo file at https://assets.example.com/logo.webp has a transparent background — also tell me its color mode and dimensions.”
Batch media audit for a developer
“I'm auditing our image library — can you pull the metadata for https://storage.myapp.com/thumbnail.gif, including its format, width, height, aspect ratio, transparency, and file size in bytes?”

Endpoint
POSThttps://api.24klabs.ai/api/v1/image-metadataWhen to prefer
Choose this endpoint when you need lightweight, structured metadata about an image — format, dimensions, mode, aspect ratio, transparency, and byte size — without performing heavier operations like object detection or OCR. It is ideal for pre-processing checks (e.g. validating upload requirements), audit pipelines, or any workflow where you need image properties quickly and cheaply at $0.002 per call.

- Invalid or unreachable image URL returns an error
- Unsupported image format returns a format error
