Pretrained computer vision classifier

Identify owl species with one API call.

A pretrained owl species classifier that sorts an image into one of 2 categories — which species of owl it is. Use the owl species API immediately, no training required, then adapt it to your own data when you need more.

Call the owl species API

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

# Get an access token: https://www.nyckel.com/docs/api/overview/authentication/
token = "YOUR_ACCESS_TOKEN"

response = requests.post(
    "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke",
    headers={"Authorization": "Bearer " + token},
    json={"data": "https://example.com/photo.jpg"},
)
print(response.json())

Example response

{
  "labelName": "Barn Owl",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 2 owl species 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 owl species classification

Wildlife Conservation

Wildlife conservation groups could use the 'owl species' identifier to monitor the presence and population sizes of different owl species in their natural habitats. This could help inform conservation efforts and prioritize resources.

Wildlife Photography

Wildlife photographers could use this function to accurately identify and label the different species of owls they capture. This can improve their portfolio organization and understanding of owl behavior.

Bird-Watching Apps

Incorporating the 'owl species' identifier into bird-watching apps will enable users to accurately identify and log sightings of different owl species. It promotes user engagements and educational interactions.

Pest Control

Pest control companies can use the identifier to understand the types of owls in an area and their feeding habits. This can help predict and control the populations of rodents and other pests that owls prey upon.

Zoo Management

Zoos can use the 'owl species' identifier for quick and accurate identification of different owl species in their care. This can assist in record-keeping, data tracking and learning purposes for visitors.

Ornithology Research

Researchers studying owls can use this function to accurately identify and classify owls in field research. This allows for more precise data collection and better understanding of owl species distribution.

Educational Tools for Schools

The 'owl species' identifier can be incorporated into educational tools to help students learn and identify different species of owls. It provides an interactive learning experience and enriches ornithology curriculum.

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 owl 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.

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.

Ready to classify owl species at scale?

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.
