How this service works

Chat, embeddings, OCR, speech-to-text, image editing, image understanding (captioning/Q&A), text-to-speech, translation, writing tools, classification tools, developer tools, local utilities, format/checksum validators, encoding & crypto utilities, date/time calculators, geo/coordinate math, math & finance calculators, novelty tools, and business/social writing generators — 179 endpoints in all, across multiple specialized self-hosted models.

Output

Returns the cropped image file as binary image data (PNG/JPEG/WebP), containing only the rectangular region specified by the x/y origin and width/height parameters.

Example use cases

Extract product photo from banner

“I have a banner image and I want to crop out just the product in the center — it starts at x=200, y=150 and is 600 pixels wide and 400 pixels tall. Can you crop that region for me?”

Remove watermark border from scan

“This scanned document has a big black border around it. Can you crop it starting at x=40, y=40 with width 720 and height 1000 to cut off the border?”

Isolate face region from group photo

“I need to pull out just the face region from this group photo — it's roughly at x=320, y=80, width 180, height 220. Please crop it to that rectangle.”

Side effects

Unsupported file format — only PNG, JPEG, and WebP are accepted
Missing required parameters — x, y, width, or height not provided returns a validation error
Payment failure — if USDC payment not included, returns HTTP 402
File too large — server may reject oversized uploads
