A pretrained type of pants classifier that sorts an image into one of 2 categories — the type of pants in the image. Use the type of pants API immediately, no training required, then adapt it to your own data when you need more.
Drop in a photo and get the prediction back. No signup, no setup.
A sample of the 30 labels this pretrained classifier chooses between.
Need a label that isn't here? Clone the classifier into your Nyckel console and edit the label set to fit your data.
Once you've added this classifier to your console, you get your own copy of it behind your own endpoint. Invoke it with any HTTP client:
curl
curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
-H "Authorization: Bearer $NYCKEL_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{"data": "https://example.com/photo.jpg"}'Python
import requests

response = requests.post(

}Trained on a Nyckel-curated dataset covering 2 type of pants categories, served on Nyckel's own infrastructure — your image stays on Nyckel.
Send an image URL or file to the invoke endpoint; the response is a label with a confidence score.
Clone it, then correct predictions and add your own samples in the console — Nyckel retrains automatically, turning this into a custom model tuned to your data.
An online clothing retailer can use the 'type of pants' identifier to automatically categorize newly listed products by type, increasing operational efficiency and improving user experience through accurate categorization.
Retail stores can use this image classification function to manage their inventory effectively, it reduces time and resources spent on manual checks and identification of pants type.
Brick and Mortar stores can implement an automated checkout system where customers scan the pants, the system identifies the type and applies the correct price, leading to a more streamlined shopping experience.
Companies that offer virtual personal shopping assistant applications can leverage this function to help users identify different pant styles fit into their fashion sense.
A company can use this identifier to analyze the followers’ photos, giving insights into what type of pants are trendier among its audience, and execute targeted advertising campaigns accordingly.
Fashion forecasting firms can use this function to analyze the street-style photos and quantify the prevalence of certain types of pants, aiding in future fashion trend predictions.
P2P clothing resale platforms can use this function in their user posting process by identifying the type of pants from the photo provided, assisting in the standardizing of product labeling across the platform.
A zero-shot classifier uses a large foundation model's general knowledge to pick between your labels — no task-specific training, so new or edited labels work immediately. A Nyckel-trained classifier has been trained on labeled examples and runs on Nyckel's own infrastructure, which typically makes it faster, cheaper per call, and more accurate on data that resembles its training set. The "Under the hood" section on this page shows which kind this classifier is, and any classifier can be adapted into a trained one by adding your own examples.
Honestly: we can't know in advance — it depends on your data stream and how closely it resembles what this classifier has seen. The reliable way to find out is to measure it on your own data: start invoking the classifier with real traffic, or upload and annotate a set of images in the console — make sure they look like your production data, not idealized examples. Nyckel's evaluation metrics then show you exactly how it performs on that data before you rely on it.
No classifier is perfect, so Nyckel is built around the correction loop: invokes can be captured for review, you confirm or correct predictions in the console, and corrections become training data. Over time the model adapts to your data distribution — accuracy on your traffic improves with use rather than staying fixed.
No. This type of pants classifier works out of the box — clone it into your console and you'll have your own API endpoint in under a minute. Training data only enters the picture when you want to adapt it: your corrected predictions and uploaded samples improve the model, and you can also edit the label set to match your needs.
Trying the classifier on this page is free with no signup. Cloning it requires a free account, and the free tier covers your first API calls each month — see nyckel.com/pricing for current limits and paid tiers.
Add this pretrained classifier to your Nyckel console — you'll get a live API endpoint in under a minute, and a path to a custom model when you need one.
