Capabilities

Powerful API Capabilities

One endpoint, every vision task you need

Object Detection

Identify and locate 80+ COCO object classes with bounding boxes. YOLOv8 and DETR models available, real-time at 60+ FPS.

Face Recognition

Detect faces, age, emotion, and 30+ attributes. Liveness detection prevents spoofing with passive depth analysis.

OCR (Text Detection)

Extract printed and handwritten text in 95+ languages. Table extraction and document layout analysis included.

Image Classification

Classify images into 10,000+ ImageNet categories. Fine-tune on your own classes with 50 sample images.

Visual Search

Find similar images across your database with vector embeddings. Hybrid text + image search supported.

Color Analysis

Extract dominant colors and palettes. Background removal, segmentation, and NSFW detection included.

Live Demo

Customer Stories

Built on VisionAI

4.9/5 average rating from 1,200+ developers

"We replaced three custom ML models and a full MLOps team with VisionAI's API. Same accuracy, 1/10th the cost, deployed in an afternoon. The Python SDK is gorgeous."

Daniel Kim

CTO, ShopAI

"80ms latency at 99.4% accuracy is wild. We process 4M images/day for surveillance — VisionAI scales without breaking a sweat. Support actually answers Slack in 5 minutes."

Aisha Bello

VP Engineering, SecureCam

"Fine-tuning custom models with 50 images was the killer feature. We trained a defect classifier for our PCB line in an hour — 96% accuracy on day one. ROI in week one."

Marco Silva

Head of ML, FactoryIQ

FAQ

Frequently Asked Questions

How do I authenticate API requests?

All requests require an API key passed via the Authorization: Bearer header. Generate keys from your dashboard — you can have multiple keys with separate rate limits and scopes. Keys can be restricted by IP, domain, or capability.

What image formats and sizes are supported?

We support JPEG, PNG, WebP, GIF (first frame), and HEIC. Maximum image size is 25MB; images larger than 1920×1080 are automatically resized. You can pass images by URL or as base64-encoded payloads (up to 10MB per request).

Can I fine-tune models on my own data?

Yes — Pro and Enterprise plans include custom model fine-tuning. Upload as few as 50 labeled images per class and we'll train a model in 1–4 hours. Fine-tuned models inherit the base model's speed and are served from your dedicated endpoint.

Do you store the images I send?

No. By default, images are processed in-memory and discarded immediately after returning results — we don't store, log, or use your images for training. Enterprise customers can request a data processing agreement (DPA) and on-prem deployment for full data sovereignty.

What SDKs and client libraries are available?

Official SDKs for Python, Node.js, Go, and Ruby are open-source on GitHub. We also provide a REST API (JSON over HTTPS), gRPC endpoints for low-latency use cases, and community-maintained libraries for PHP, Rust, Java, and .NET.
