Pretrained computer vision classifier

Identify hamster species with one API call.

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

Call the hamster species 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": "Roborovski Hamster",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 2 hamster species 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 hamster species classification

Pet Store Management

Pet stores can use the 'hamster species' identification function to categorize hamsters accurately. This would improve their inventory management and assist customers in making accurate choices when purchasing.

Hamster Breeding Programs

Breeders can use this function to accurately identify and categorize hamster species, ensuring the purity of bloodlines, tracking health trends by species, and maximizing the effectiveness of their breeding programs.

Research and Conservation Efforts

Organizations focusing on animal research and conservation can use this function to identify hamster species in different habitats and study their population distribution and growth trends.

Customized Pet Care Products

Manufacturers of hamster care products can use this function to design specific products for each species, resulting in improved customer satisfaction and product sales.

Exotic Pet Applications

Custom agencies or veterinary clinics can use this function to effectively identify any exotic hamster species to ensure compliance with local laws and regulations, and provide the appropriate care.

Animal Shelter Operations

The function can help animal shelters to classify incoming hamsters by species, assisting in determining the best care, dietary needs, and prospective adoption home for each animal.

Educational Apps Development

Developers of educational apps about animals can integrate this function into their applications, providing users with accurate information about different hamster species, thus enhancing the learning process.

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 hamster species 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.
