A pretrained skin bumps classifier that sorts an image into one of 2 categories — the type of skin bump it is. Use the skin bumps 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 25 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
import requests

response = requests.post(

}Trained on a Nyckel-curated dataset covering 2 skin bumps 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.
Dermatologists could use this image classification function to optimize the preliminary diagnostic process by identifying various skin conditions including benign moles, pimples, and more. Patients would be able to get a primary analysis before meeting the doctor, saving valuable time for both parties.
The pandemic spurred the development of telemedicine services. A skin bump identifier would let healthcare professionals diagnose skin conditions remotely, providing convenience and safety for patients and doctors alike.
Cosmetic companies can utilize the tool to identify skin problems unique to their customers to help recommend suitable skincare products that specifically target these problems.
The tool could be used as a training source for medical students, helping them learn how to identify skin conditions more efficiently and accurately.
Apps could integrate this function to help users monitor changes in their skin health over time. Users could upload images and get information about potential skin conditions, enhancing self-care routines.
This tool can serve as an initial diagnosis platform for online pharmacies. Customers can upload images of their skin condition, and the tool can assist in recommending over-the-counter products that could potentially aid their condition.
Health insurers could employ this function to better understand the medical conditions of their clients, leading to more comprehensive coverage plans and swifter insurance claim processes.
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 skin bumps 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.
