Pretrained computer vision classifier

Identify plant health with one API call.

A pretrained plant health classifier that sorts an image into one of 5 categories — the health status of various plant species.. Use the plant health API immediately, no training required, then adapt it to your own data when you need more.

Call the plant health API

Get your own copy of this classifier behind your own endpoint — callable from any HTTP client:

API quick start
curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"data": "https://example.com/photo.jpg"}'

Example response

{
  "labelName": "Damaged",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 5 plant health 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 plant health classification

Crop Disease Detection

The plant health identifier can analyze images of crops to identify signs of disease early in their development. This allows farmers to take timely action to treat infected plants, potentially saving entire harvests and reducing the spread of disease.

Precision Agriculture Monitoring

Farmers can leverage the plant health identifier to monitor the health of their crops through aerial images captured by drones. This technology enables targeted interventions, such as applying fertilizers or pesticides only where needed, optimizing resources and reducing environmental impact.

Nursery Plant Assessment

Nurseries can use the plant health identifier to assess the health of young plants before they are sold. By identifying unhealthy plants early, nurseries can improve their stock quality and ensure that customers receive vibrant and healthy plants.

Landscape Maintenance

Landscaping companies can implement the plant health identifier to assess the health of plants in commercial and residential properties. By identifying stressed or diseased plants, they can provide better maintenance services and enhance the overall aesthetic value of the landscapes they manage.

Research and Development

Agricultural researchers can utilize the plant health identifier in experiments focused on plant genetics or growth conditions. The ability to quickly and accurately assess plant health can yield more precise results and lead to advancements in plant breeding techniques.

Integrated Pest Management

The plant health identifier can assist in integrated pest management by assessing the impact of pests on plant health. By monitoring plants over time, agricultural professionals can develop more effective pest control strategies tailored to specific situations.

Community Education and Engagement

Local agricultural organizations can use the plant health identifier to educate community members about plant care and pest identification. Workshops and demonstrations can utilize the technology to show how to recognize healthy plants, promoting better gardening practices among residents.

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 plant health 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.
