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. Pay per call with crypto — no signup — or get an API key.
Output
Returns a JSON object containing the engine used for processing, the output image format, and the background-removed image encoded as a base64 string. The resulting image typically has a transparent background where the original background was.
Example use cases
E-commerce product photo cleanup
“I have a JPEG of a product on a cluttered desk — can you remove the background so I get just the product on a clean transparent background for my store listing?”
Logo isolation for design work
“Strip the white background from this PNG logo file so I can use it on different colored backgrounds in my designs.”
Portrait cutout for profile image
“I want to cut out just the person from this photo — remove everything in the background and give me a PNG with just them.”
