Universal
ALPR API

Automate global logistics, tolling, and smart parking. Our specialized OCR natively parses multi-plate layouts (e.g., trailers), complex dual-scripts, and regional formatting with zero hallucination.

Engineered for Global ALPR Scale

Multi-Plate Detection

Returns an array of plates. Easily parses stacked trailer and prime mover plates without merging them into broken strings.

Global Script Retention

Accurately extracts Arabic, Cyrillic, and Asian scripts exactly as printed. No forced translation.

Color & Type Analysis

Identifies dominant background colors (white, yellow, green) to instantly route commercial vs. private vehicles.

Zero Hallucination

Strictly returns 'null' for illegible plates instead of guessing, keeping your downstream databases clean.

How it works

Integrate robust vehicle identification into your infrastructure. Experience the extraction flow using our free ALPR scanner tool.

01

Capture Image

A toll gantry camera, parking barrier, or mobile device captures a photo of the vehicle's license plate.

02

SEA-Optimized Extraction

Our engine locates the plate, identifies the layout, and extracts native characters without forcing Western OCR assumptions.

03

Structured Output

Receive the exact plate number, region text, plate color, and vehicle type in clean JSON to trigger your barriers.

Trusted by SEA Infrastructure

Powering tollways, smart parking, and logistics across Southeast Asia.

Standard APIs kept concatenating our prime mover and trailer plates into one invalid 16-character string. StructOCR's array format solved our gate automation instantly.
