Perfect Corp.'s YouCam API Hackathon Is Back, Now Focused on eCommerce with a $6,000 Prize Pool

What's New in Round Two: The eCommerce Challenge

The second round widens the brief from apparel try-on to eCommerce. Developers can use any YouCam API to build a working web or mobile app with clear value for shoppers or retailers. Each team submits a code repository, a project description, and a 1 to 3 minute demo video, and judges score projects on technological implementation, design, potential impact, and quality of the idea.

The top three teams win $2,500, $1,000, and $500. Two new $1,000 awards recognize the best project from a team with at least one self-identified woman member (Women in Tech Award) and the best project from a team with at least one enrolled student (Rising Star Award). Participants can also earn 500 bonus API units for each qualifying demo video they share on social media, up to two per participant.

Submissions close November 2, 2026, at 11:45 a.m. ET, and winners will be announced on or around November 24, 2026.

Meet the Round One Winners

The first YouCam API hackathon ran from July 6 to August 17, 2026, and drew 1,280 registered developers and 238 project submissions. Each winning team picked a problem that shoppers or brands face every day and solved it with YouCam AI.

• Beauty shopping that works without a screen. Aloud, the first-place project, lets blind and low-vision shoppers choose skincare and check their makeup by voice, on their own. The app runs the YouCam AI Skin Analysis API and AI Skin Tone Analysis on a selfie, turns the scores into spoken guidance, and checks lighting before it gives an answer. In testing on iPhone, all 10 scans returned a result in under 30 seconds. The team built Aloud for the estimated 8.5 million Americans who are blind or have serious vision loss.
• Catalogs that show every customer. ShadeSpan, the second-place project, uses AI Clothes Virtual Try-On and AI Skin Analysis to show each garment in a collection on six skin tones and score how well the color holds up on each one. In its demo catalog, only 14.3% of garments passed on all six tones. Checking a 14-piece collection this way with photo shoots would take 84 separate shoots. CASTING takes the same idea further for merchandisers: it places one product photo on eight people with measured skin tones in about 28 seconds, using four YouCam APIs for try-on, skin analysis, skin type, and facial color tones.
• Virtual try-on that shoppers can trust. KeepMe lets shoppers decide which parts of their appearance AI try-on is allowed to change, such as their face, hair, or glasses, and flags and repairs any change they did not approve. ConfidFit brings YouCam AI clothing try-on to Shopify stores with a clear label that each image is a visual preview, not a fit guarantee. ConfidFit is now live on the Shopify App Store.

Production-Ready AI Lets Small Teams Build Fast

Every winning team built on the same YouCam APIs that power AI experiences for Perfect Corp.’s 800+ brand partners. The YouCam API covers AI skin analysis, virtual try-on for makeup, hair, clothing, and accessories, and AI image and video generation, all delivered as standard REST APIs.

Because the skin analysis, skin tone, and try-on models are already production-ready, teams did not need to collect data or train their own models. They spent their six weeks on the problem they wanted to solve.

"Beauty tech should work for every shopper, including people who cannot see a screen and people whose skin tone rarely appears in product photos," said Alice Chang, Founder & CEO of Perfect Corp. "The teams in our first hackathon showed that YouCam AI can close those gaps in a matter of weeks. We are opening a second round to find more ideas that make beauty and fashion shopping work for everyone."
