A pretrained cat color classifier that sorts an image into one of 10 categories — what color a cat is. Use the cat color 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 23 labels this pretrained classifier chooses between.

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

}Trained on a Nyckel-curated dataset covering 10 cat color 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.
Shelters and adoption agencies can utilize the 'cat color' identifier to streamline the process of matching potential adopters with cats that meet their preferences. By categorizing cats based on color, agencies can more effectively market and highlight cats, increasing the likelihood of adoption and helping find homes for more animals.
Online pet product retailers can implement the 'cat color' identifier to enhance their inventory categorization for cat-related products. By tagging products with images of cats in various colors, customers can quickly navigate and find items that reflect their own pets’ colors, improving the shopping experience and potentially boosting sales.
Veterinary clinics can incorporate the 'cat color' identifier into their patient management systems to organize records more effectively. By categorizing pets by color, vets can simplify appointment scheduling and reduce misidentifications, leading to better service and care for each animal.
Pet influencers and brands can use the 'cat color' identifier to create engaging content tailored to specific cat colors. By segmenting their audience based on this classification, they can deliver targeted posts, promote products, or share stories that resonate more with their followers, enhancing community engagement.
Pet insurance companies can utilize the 'cat color' identifier as part of their risk assessment process. By understanding the demographics associated with different cat colors, insurers can analyze correlations with health issues or behavioral traits, ultimately refining their policy offerings and pricing strategies.
Developers of smart pet technology, like cameras or feeders, can use the 'cat color' identifier to enhance image recognition features. By training algorithms to recognize different cat colors, these technologies can improve their accuracy in monitoring, engaging, or interacting with various pets, leading to a better user experience.
Artists and merchandise designers can leverage the 'cat color' identifier to create personalized products for cat owners. By allowing customers to specify their pet's color, businesses can offer custom art prints, accessories, and apparel that resonate more with cat lovers, driving sales and customer satisfaction.
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 cat color 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.
