- What does the virtual try-on API return?
- A photoreal image of the garment rendered on the shopper, plus a fit prediction: a recommended size, tight/true/loose probabilities that sum to 1, a confidence score, and the assumptions used (e.g. fabric unknown).
- How is this different from other virtual try-on APIs?
- Most return only an image. WooChim also returns the sizing decision computed from the shopper's measurements against your size chart — the number that reduces wrong-size returns, not just a nicer product photo.
- Do you charge per render?
- Each plan includes a monthly allowance of fit analyses and HD try-on renders. Analyses are cheap and generous; photoreal renders run on GPU infrastructure and get a smaller allowance. Overage on either bills per-unit. See the pricing on the business page.
- Can I embed it without writing code?
- Yes — drop in the WooChim widget script with your publishable key and a size table, and shoppers get an inline size checker that calls the fit API.
