Detect, validate, and search faces with one simple API
ProFaceFinder API lets you add reverse face search engine and facial recognition to your app without building or maintaining complex machine-learning systems.
Upload an image → detect faces → validate → search for matches → receive results in JSON.
Built for startups, SaaS platforms, and developers who need a reverse image search API or facial recognition API that works reliably in production.
How ProFaceFinder API Works
ProFaceFinder API is the best reverse image face search API for developers who need accurate face detection, validation, and matching without complex setup.
1. Upload an Image via API
Send an image file to the API.
- Max file size: 10MB
- REST-based upload
- Supported formats: JPG, JPEG, PNG, WebP
- No preprocessing required
2. Face Detection, Validation & Search
ProFaceFinder API detects faces and validates each image based on rules you define. You stay in control of what’s accepted, what’s rejected and how results are handled.
- Apply custom validation rules to every upload
- Receive clear, actionable error responses when validation fails
- Enforce consistent image standards across your product
You decide what “valid” means.
