A pretrained license plates classifier that sorts an image into one of 2 categories. Use the license plates 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 2 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

}Trained on a Nyckel-curated dataset covering 2 license plates 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.
The 'license plates' identifier can be used by businesses in the logistics industry to track the movement and location of their fleets. By classifying and recognising license plates, companies can monitor vehicle locations and schedule better.
Traffic management companies can use this image classification function to identify license plates in traffic, helping to manage traffic flow, detect congestion, and carry out traffic studies more accurately.
Parking lot operators can employ the identifier to monitor and manage vehicle parking. It would aid in automatic ticket issuance at entry and exit points, ensuring fraud-free payment processes and efficient management of parking spaces.
Insurance agencies and law enforcement can utilize the image classification to identify stolen vehicles. By flagging the license plates of stolen cars, any appearance can be traced, aiding in vehicle recovery.
The 'license plates' identifier can be used in the automation of toll booths. It can classify and recognize license plates to facilitate automatic payment, reducing human error and queues at toll plazas.
Rental companies can use the function to track their vehicles. This can assist in record keeping, ensuring the car is returned on time, or locating the car if it's not returned.
Traffic officials can utilize the license plate identifier for enforcing road safety regulations, identifying vehicles exceeding speed limits, running a red light or committing similar offenses, helping to create safer streets.
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 license plates 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.
