Pretrained computer vision classifier

Identify type of shirt with one API call.

A pretrained type of shirt classifier that sorts an image into one of 2 categories — what type of shirt it is. Use the type of shirt API immediately, no training required, then adapt it to your own data when you need more.

What this type of shirt classifier recognizes

A sample of the 30 labels this pretrained classifier chooses between.

Polo Shirt
T-Shirt

Call the type of shirt API

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

# Get an access token: https://www.nyckel.com/docs/api/overview/authentication/
token = "YOUR_ACCESS_TOKEN"

response = requests.post(
    "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke",
    headers={"Authorization": "Bearer " + token},
    json={"data": "https://example.com/photo.jpg"},
)
print(response.json())

Example response

{
  "labelName": "Polo Shirt",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 2 type of shirt categories, served on Nyckel's own infrastructure — your image stays on Nyckel.

Input
Image

Send an image URL or file to the invoke endpoint; the response is a label with a confidence score.

Make it yours
Adaptable

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.

More than a demo: this page is one of thousands of pretrained functions on Nyckel, an ML classification platform. You can invoke classifiers by API, review predictions, correct labels, collect samples from production traffic, and promote any pretrained function to a private custom model — without changing your integration.

Where teams use type of shirt classification

E-commerce Catalogue Organization

This function can be used by online retailers to automatically categorize different shirts within their inventory based on the type of shirt, streamlining the product organization process.

Personalized Fashion Suggestions

An online fashion platform can utilize this function to suggest personalized clothing items to its customers, by identifying and recommending various types of shirts that align with a user's past purchase or browsing history.

Inventory Management

Retail stores can leverage the 'type of shirt' identifier to monitor their inventory efficiently, by automatically identifying the types of shirts in stock and those that need to be reordered.

Real Time Store Assisting

Brick and mortar retail stores can implement this function into mobile apps to aid customers in identifying and finding different types of shirts available in the store.

Clothes Recycling and Donation

Charity organizations can use this function to sort out donated clothes into specific categories, enabling them to effectively manage their inventory and distribution.

AI Personal Shopper

A digital personal shopper can use this function to curate a personalized wardrobe for the user, by identifying the types of shirts in the user’s existing collection and supplementing with complementary styles.

Fashion Trend Analysis

Fashion market researchers can utilize this function to identify and track the popularity of different types of shirts over a period of time, aiding in making trend predictions for design and production.

Common questions

What's the difference between a zero-shot and a Nyckel-trained classifier?

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.

How do I know whether this will work for my application?

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.

What happens when it makes a mistake?

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.

Do I need training data to get started?

No. This type of shirt 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.

What does it cost to try?

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.

Ready to classify type of shirt at scale?

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.
