AI image generator from text built on fal.ai

Description

Who this template is for

This template is for developers, content creators, or application builders who want to integrate an AI-powered text-to-image generation service into their applications or systems via an API endpoint.

Use case

Creating a secure API endpoint that converts text prompts into AI-generated images, with built-in content moderation to prevent inappropriate content generation. This can be used for creative applications, content creation tools, prototyping interfaces, or any system that needs on-demand image generation.

How this workflow works

Receives text prompt through a webhook endpoint
Filters the prompt for inappropriate content using AI moderation
Submits valid prompts to the Fal.ai Flux image generation service
Polls for completion status and retrieves the generated image when ready
Returns the image results in a structured JSON format to the client

Set up steps

Create a Fal.ai account and obtain API credentials
Configure the HTTP Header Auth credentials with your Fal.ai API key
Set up an OpenAI API key for the content moderation component
Deploy the workflow and note the webhook URL for your API endpoint
Test the endpoint by sending a POST request with a JSON body containing a "prompt" field
