Pretrained computer vision classifier

Identify the color of a pair of socks with one API call.

A pretrained the color of a pair of socks classifier that sorts an image into one of 10 categories — the color of a pair of socks. Use the the color of a pair of socks API immediately, no training required, then adapt it to your own data when you need more.

Call the the color of a pair of socks 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": "Beige",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 10 the color of a pair of socks 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 the color of a pair of socks classification

E-commerce Product Verification

An online retail platform can utilize the image classification function to automatically verify the color of socks uploaded by sellers. This ensures that the product images match the listed descriptions, reducing customer complaints and returns due to color discrepancies.

Inventory Management

A warehouse can implement the image classification to categorize and manage sock inventory by color. This allows for easier tracking of stock levels and can help automate reordering processes based on color trends.

Personalized Recommendations

A mobile app can use the function to analyze users' sock preferences based on the colors they buy or view. This data can help generate personalized recommendations, increasing user engagement and sales.

Quality Control in Manufacturing

A sock manufacturing facility can incorporate the image classification technology in their production line to ensure color consistency. This real-time quality control helps maintain brand standards and reduce waste from defective products.

Market Analysis

Fashion retailers can use the image classification function to analyze current trends in sock colors across social media platforms. This insight can guide their design and purchasing decisions, aligning inventory with customer preferences and seasonal trends.

Digital Styling Assistant

An AI-driven fashion styling app can leverage the classification function to suggest matching outfits based on the sock color selected by the user. By providing seamless styling options, it enhances the user experience and encourages cross-selling opportunities.

Customer Feedback Analysis

Companies can use image classification to analyze customer-submitted photos of their socks for feedback purposes. By identifying common color-related issues, businesses can make informed improvements to their products and marketing strategies.

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 the color of a pair of socks 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.
