BlackForestLabs

Features 🔥

• Fully generated C# SDK based on official BlackForestLabs OpenAPI specification using AutoSDK
• Same day update to support new features
• Updated and supported automatically if there are no breaking changes
• All modern .NET features - nullability, trimming, NativeAOT, etc.
• Support .Net Framework/.Net Standard 2.0

Usage

using BlackForestLabs;

using var client = new BlackForestLabsClient(apiKey);

CLI

dotnet tool install --global BlackForestLabs.CLI --prerelease
black-forest-labs api --help

Get Credits

Basic example showing how to create a client and check your credits balance.

using var client = new BlackForestLabsClient(apiKey);

// Check your remaining credits balance.
var response = await client.GetCreditsV1CreditsGetAsync();

Image Generation

Generate an image using FLUX Pro 1.1 and poll for the result.

using var client = new BlackForestLabsClient(apiKey);

// Submit an image generation request using FLUX Pro 1.1.
var response = await client.Models.FluxPro11V1FluxPro11PostAsync(
    prompt: "A serene mountain landscape at sunset",
    width: 1024,
    height: 768);

// The API returns a task ID. Poll for the result using GetResult.
var asyncResponse = response.Value1;
if (asyncResponse is not null)
{
    var result = await client.Utility.GetResultV1GetResultGetAsync(
        id: asyncResponse.Id);

}

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.
