How does the API detect nail shape and placement?

The API runs an AI detection step that finds each finger's position and traces the nail bed shape, including almond, stiletto, square, oval, and squoval, from a single photo, so every rendered color or design sits exactly where a real manicure would.

How do I get started with the Color-Changing Nail Try-On API?

Get an API key, then send a hand photo through a single RESTful POST request. Code snippets are available in JavaScript, Java, Flutter, Python, PHP, Node.js, and cURL, and the API Playground lets you test results before writing any code.

What image or input requirements are needed?

The API accepts hand selfies, professional product photography, camera feeds, or image URLs. A clear, well lit photo showing the fingers and nails gives the most accurate detection and rendering results.

When are API units consumed?

An API unit is consumed each time a request successfully returns a rendered image. Failed requests or detection errors are not charged, so testing and retries during integration stay cost controlled.

Q: What is color-changing nail try-on?

Color-changing nail try-on lets users preview mood, thermal, or duochrome polish effects on a photo of their own hand before committing to a color. The API renders the shift in shade, finish, and light response so the look matches what a real color-changing polish would show.

Give users a hyper-realistic preview of color-changing and mood nail polish looks in seconds. AI point detection maps every nail bed, then renders infinite shades, textures, and finishes for a true-to-life try-on experience.
