Pretrained text classifier

Identify cleanliness rating with one API call.

A pretrained cleanliness rating classifier that sorts text into one of 5 categories — the cleanliness rating of various environments. Use the cleanliness rating API immediately, no training required, then adapt it to your own data when you need more.

Call the cleanliness rating 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": "The text you want to classify"}'

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": "The text you want to classify"},
)
print(response.json())

Example response

{
  "labelName": "1 Star",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 5 cleanliness rating categories, served on Nyckel's own infrastructure — your text snippet stays on Nyckel.

Input
Text

Send raw text 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 cleanliness rating classification

Hospitality Quality Control

Hotels and restaurants can use the cleanliness rating identifier to automatically assess reviews and feedback from guests. This will help them quickly identify areas needing improvement and enhance overall customer satisfaction by maintaining high cleanliness standards.

Food Safety Compliance

Food industry regulators can utilize the cleanliness rating identifier to analyze reports from various establishments. By identifying compliance issues through this function, they can foster safer food environments for consumers and ensure higher hygienic standards in food service operations.

Real Estate Property Management

Property management companies can leverage this tool to monitor cleanliness ratings of their rental properties through tenant feedback. By addressing cleanliness issues proactively, they can improve tenant retention and enhance the property’s marketability.

Tourism Marketing Insights

Tourism boards can assess cleanliness ratings derived from visitor reviews to promote destinations better. Positive cleanliness indicators can be highlighted in marketing materials to attract more tourists, enhancing the region’s reputation and driving economic growth.

Retail Environment Assessment

Retailers can analyze customer feedback related to store cleanliness to identify patterns that may affect shopping experiences. This function can prompt targeted clean-up efforts and ultimately lead to increased customer satisfaction and sales.

Event Venue Evaluation

Event coordinators can use the cleanliness rating identifier to evaluate potential venues based on historical cleanliness feedback from past events. Choosing a venue with high cleanliness ratings can enhance the overall experience for attendees and reflect positively on the event organizers.

Public Health Monitoring

Public health organizations can implement the cleanliness rating identifier to track cleanliness trends across various public spaces, such as parks or restrooms. This information is vital for ensuring community health and can prompt timely interventions when needed.

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 text samples 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 cleanliness rating 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 cleanliness rating 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.
