Pretrained computer vision classifier

Identify badge photo quality with one API call.

A pretrained badge photo quality classifier that sorts an image into one of 10 categories — the quality of your badge photo. Use the badge photo quality API immediately, no training required, then adapt it to your own data when you need more.

Call the badge photo quality 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": "Acceptable",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 10 badge photo quality 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 badge photo quality classification

Enhanced ID Verification

This function can be implemented in security systems to assess the quality of badge photos. By ensuring that images meet specific quality standards, organizations can improve the accuracy of identity verification processes during access control.

Fraud Prevention in Events

Event organizers can use the badge photo quality identifier to filter out low-quality images. This prevents fraudulent registrations by ensuring that all attendees have legitimate and recognizable identification badges.

Recruitment Process Optimization

Human resources departments can leverage this function to validate employee photos on badges. By ensuring only high-quality images are used, it helps maintain a professional appearance and consistency in employee identification.

Compliance with Branding Standards

Companies can deploy the badge photo quality identifier to ensure that employee photos adhere to branding guidelines. This ensures uniformity in appearance and enhances the organization's professional image throughout all internal and external communications.

Quality Control in Photo Submissions

Online platforms that require users to upload identification badges can use this function to automatically assess image quality. This reduces the administrative burden associated with manually reviewing submissions and ensures that only suitable images are processed.

Security Training Simulations

In training scenarios for security personnel, integrating the badge photo quality identifier can help educate staff on recognizing valid badges. This enhances their skills in identifying potential fraud and maintaining high security standards in their operations.

Improved Customer Experience

Organizations can utilize this identifier in customer service departments to quickly assess badge photo quality. By ensuring that customer identification is clear and identifiable, service representatives can provide faster and more accurate assistance to clients.

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 badge photo quality 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.
