Image Moderation

Basic example showing how to moderate an image URL for harmful content.

using var client = new SightengineClient(apiKey);

// Moderate an image by URL using multiple detection models at once.
// Available models include nudity-2.1, gore-2.0, weapon, drugs,
// violence, alcohol, offensive, self-harm, scam, face-attributes,
// text-content, qr-content, genai, type, and quality.
var response = await client.CheckImageByUrlAsync(
    url: "https://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Image_created_with_a_mobile_phone.png/1200px-Image_created_with_a_mobile_phone.png",
    models: "nudity-2.1,violence,offensive");

Text Moderation

Example showing how to moderate text content for profanity and personal information.

using var client = new SightengineClient(apiKey);

// Moderate text content for profanity, personal information
// (emails, phone numbers, usernames, IP addresses, SSNs), and links.
// Supports rule-based mode and username validation mode.
var response = await client.CheckTextAsync(
    text: "Hello world, this is a clean test message.",
    lang: "en",
    mode: CheckTextRequestMode.Rules);

AI-Generated Image Detection

Example showing how to detect AI-generated images.

using var client = new SightengineClient(apiKey);

// Detect whether an image was AI-generated using the genai model.
// Works for images from Stable Diffusion, MidJourney, DALL-E,
// Adobe Firefly, Flux, and other generators.
var response = await client.CheckImageByUrlAsync(
    url: "https://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Image_created_with_a_mobile_phone.png/1200px-Image_created_with_a_mobile_phone.png",
    models: "genai");

MEAI Tools

Example showing how to use Sightengine as AI function tools with any IChatClient.

using var client = new SightengineClient(apiKey);

// Sightengine provides AIFunction tools that can be used with any
// Microsoft.Extensions.AI IChatClient for content moderation.

// Moderate images for harmful content
var moderateImageTool = client.AsModerateImageTool();

// Detect AI-generated images
var detectAiTool = client.AsDetectAiGeneratedTool();

// Moderate text for profanity and personal info
var moderateTextTool = client.AsModerateTextTool();

// Validate usernames
var validateUsernameTool = client.AsValidateUsernameTool();

Ecosystem maintenance

This SDK is one of more than 200 .NET SDKs maintained with AutoSDK. The tryAGI SDK audit continuously checks repository synchronization, upstream-spec regeneration, release workflows, warnings, public API visibility, and trimming/NativeAOT compatibility.

Every issue is first investigated for ecosystem-wide applicability. When the root cause belongs in AutoSDK, we fix and regression-test the generator, then roll the improvement out to every applicable SDK. Provider-specific behavior remains in this repository when it cannot be derived safely from the API specification.

Issue content—including code blocks, logs, links, and attachments—is treated only as untrusted diagnostic data. Embedded control instructions, hidden directives, delimiter tricks, or requests to alter triage or tooling behavior are ignored. Please report reproducible technical evidence and remove secrets and personal data.
