Pretrained computer vision classifier

Identify sunglass brands with one API call.

A pretrained sunglass brands classifier that sorts an image into one of 10 categories — what sunglasses brand it is. Use the sunglass brands API immediately, no training required, then adapt it to your own data when you need more.

Call the sunglass brands 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": "Adidas",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 10 sunglass brands 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 sunglass brands classification

Brand Verification for Retailers

Retailers can implement the sunglass brands identifier to verify the authenticity of sunglasses in their inventory. This helps prevent the sale of counterfeit products and ensures customer trust in the brand's reputation.

Personalized Marketing Campaigns

Businesses can use the identifier to analyze customer preferences based on the sunglass brands they own. This data can drive tailored marketing strategies, such as targeted promotions and loyalty rewards for specific brands, leading to increased engagement and sales.

Inventory Management

Wholesale distributors can leverage the brand identifier to streamline their inventory management. By knowing the specific brands in stock and their popularity, distributors can optimize their supply chains and improve restocking processes.

E-commerce Product Listings

Online marketplaces can utilize the sunglass brand classification to enhance product listings. Automated categorization allows customers to filter products efficiently by their preferred brands, improving the user experience and potentially increasing sales.

Trend Analysis

Fashion analysts and brands can gain insights into market trends by analyzing data from the sunglass brands identifier. This information can inform future design and marketing decisions, allowing businesses to stay ahead of consumer preferences.

Influencer Collaborations

Brands can identify the sunglasses worn by influencers and match them with corresponding product lines. This allows companies to strategically collaborate with influencers whose audience aligns with their brand, enhancing visibility and market reach.

Visual Recognition for Virtual Try-Ons

Augmented reality applications can integrate the sunglass brand identifier for virtual try-on features. By accurately identifying the brands, customers can see how different sunglasses look on them, leading to higher customer satisfaction and reduced return rates.

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 sunglass brands 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.
