A pretrained height of truck in feet classifier that sorts an image into one of 10 categories — the height of the truck in feet. Use the height of truck in feet 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 51 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

}Trained on a Nyckel-curated dataset covering 10 height of truck in feet 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.
Logistics companies can utilize the height classification function to ensure that trucks comply with height regulations for various routes. This helps in avoiding fines and route disruptions caused by over-height vehicles entering restricted areas.
Toll operators can implement this function to accurately classify vehicle heights for automated toll collection systems. This ensures that trucks are charged appropriately based on their height, enhancing revenue accuracy and operational efficiency.
Transportation safety agencies can leverage this function during vehicle inspections to quickly identify and document the height of trucks. This contributes to improved safety standards and helps in enforcing regulations regarding load limits and vehicle dimensions.
Delivery and logistics companies can use this height classification to optimize routes based on vehicle dimensions. By avoiding low bridges and overpasses, they can reduce the likelihood of accidents and improve delivery timelines.
Insurance companies can integrate this function into their underwriting processes to assess vehicle heights for risk evaluations. Accurately classifying truck heights can help determine premiums and coverage specifics relevant to a truck's operational capabilities.
Cities and municipalities can adopt this function in smart parking management systems to determine the height of vehicles entering parking facilities. This ensures that trucks are directed to appropriate parking areas and that space utilization is maximized.
E-commerce platforms can employ this classification to inform customers about delivery vehicle requirements. This ensures that customers purchase items that comply with their delivery settings, streamlining the last-mile delivery process and improving 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 height of truck in feet 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.
