Number Plate Recognition
API for developers
NPR API delivers production-grade number plate recognition with 99.8% accuracy. Read licence plates from images and video with real-time results.
Number plate recognition built for scale.
Our NPR engine is trained on millions of diverse plate samples to ensure robust recognition in low light, high angles, and challenging weather conditions.
Real-time Plate Recognition
Optimised inference engine delivering real-time number plate reads. Perfect for high-speed tolling, parking, and access control applications.
Global Plate Support
Recognise number plates from 90+ countries out of the box. Automatically detects region and format, including two-line plates and special characters.
Vehicle Analytics
Beyond just number plates. Extract vehicle make, model, colour, and body type in a single NPR API call for comprehensive tracking.
Cloud or On-Premise
Use our globally distributed number plate recognition API or deploy the Docker container directly to your edge devices.
Privacy First
GDPR and CCPA compliant. Zero-retention policy options available. Images are processed in memory and immediately discarded.
Developer Centric
Integrate NPR API with SDKs for Python, Node, Go, and Java. Comprehensive webhooks, detailed logging, and sandbox environment.
Integrate in minutes.
Send an image, get structured number plate data back as JSON. Pick your language and start reading plates.
curl -X POST https://api.nprapi.com/v1/plate-reader \ -H "Authorization: Bearer YOUR_API_KEY" \ -F "image=@/path/to/vehicle.jpg"
import npr_api client = npr_api.Client('YOUR_API_KEY') result = client.read_plate('vehicle.jpg') print(result.plate)
const NPR = require('npr-sdk'); const client = new NPR('YOUR_API_KEY'); const result = await client.read('vehicle.jpg');
$client = new NprApi\Client('YOUR_API_KEY'); $result = $client->readPlate('vehicle.jpg'); echo $result->plate;
const response = await fetch('https://api.nprapi.com/v1/plate-reader', { method: 'POST', headers: { Authorization: 'Bearer YOUR_API_KEY' }, body: formData, }); const data = await response.json();
