NSFW Detection API

degraded 3,363 Subscribers

Moderate images automatically with on-device machine learning. Classify any image across five categories — neutral, drawing, sexy, porn and hentai — and receive per-class probabilities, the top class, a combined NSFW score and a clear verdict (safe, questionable or nsfw). A simpler check endpoint returns a single safe/unsafe decision against a threshold you choose, ideal for upload gates and user-generated-content pipelines. Supply an image by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked, and large images are downscaled automatically. Runs locally on TensorFlow (NSFWJS / MobileNetV2) — no third-party upstream and no per-image cloud cost — with a warm model that keeps inference fast. Ideal for community platforms, marketplaces, dating and chat apps, and any service that accepts user images.

Placeholder API

A fast, fully-local SVG generator for mockups and UIs: placeholder images (a sized rectangle with centered text and automatic contrast), initials avatars (with a deterministic colour derived from the name, in a circle or square), and identicon-style symmetric patterns generated deterministically from any seed. Every endpoint returns the JSON envelope or, with raw=1, the raw SVG so the URL can be used directly as an image source. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for prototypes, dashboards, user avatars, empty states and design systems.

Image API

Inspect image metadata (dimensions, format, size, colour space, transparency) and resize or convert images between JPEG, PNG, WebP and AVIF straight from a URL. Perfect for thumbnails, format optimisation and on-the-fly image transforms.

QR Code API

Generate QR codes on demand as a base64 PNG, an SVG, or a raw embeddable image. Customise size, quiet-zone margin, error-correction level and foreground/background colors. Encode URLs, text, Wi-Fi, vCards and more.

Face Detection API

Detect human faces in an image and analyse each one with on-device machine learning: get the bounding box and a detection confidence, an estimated age, the predicted gender with its probability, and the dominant facial expression together with the full per-expression breakdown (neutral, happy, sad, angry, fearful, disgusted and surprised). A lightweight count endpoint returns just the number of faces and their boxes for fast gating. Supply an image by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked, and large images are downscaled automatically. Runs locally on TensorFlow (face-api) — no third-party upstream and no per-image cloud cost — with warm models that keep inference fast. Ideal for photo and avatar apps, audience analytics, smart cameras, auto-cropping and accessibility.
