A pretrained turtle species classifier that sorts an image into one of 2 categories — which species of turtle it is. Use the turtle species 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 30 labels this pretrained classifier chooses between.
Need a label that isn't here? Clone the classifier into your Nyckel console and edit the label set to fit your data.
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

}No labeled training data behind this function — it picks between the 2 labels using a foundation model's general world knowledge (currently GPT-4o-mini). Your image is forwarded to the model provider at inference time. Because it's zero-shot, cloned label edits take effect immediately, no retraining needed.
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.
Ecological conservation organizations can utilize the turtle species identifier to better monitor the population and distribution of various turtle species in different habitats during their research studies.
Pet shops, turtle breeders, and buyers can use the tool to correctly identify the species of a turtle. This can help ensure the proper care and treatment for specific species, as well as to abide by regulations for species that are illegal to trade.
Wildlife rescue and rehabilitation centers can use the function to correctly identify the species of rescued turtles. This ensures appropriate medical treatment and rehoming efforts.
Businesses in the eco-tourism sector can utilize the tool to provide wildlife spotting tours with accurate information on turtle species found in local habitats, enhancing tourist experiences.
Academic institutions and researchers studying biodiversity can use the turtle species identifier as a tool for accurate data collection on different turtle species in various environments.
Aquariums, zoos, and marine parks can leverage this tool to accurately label and provide information to the public about different species of turtles in their exhibits.
Companies conducting Environmental Impact Assessments (EIA) can use this function to identify the presence of different turtle species in an area where they plan to develop, assisting them to comply with wildlife protection laws and regulations.
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 turtle 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.
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.
