Frequently Asked Questions

What is an image generation API?

An image generation API lets you create or modify images automatically. Instead of designing each image manually, you send data to the API (like text or layout instructions), and it returns a finished image. It's like having a robot designer that works through code!

Do I need to know how to code to use these tools?

Not at all! Most of these platforms offer no-code solutions like:

• Connections to your spreadsheets (upload CSV or connect to Google Sheets)
• Simple form builders
• Visual editors that work like Canva
• Integrations with Zapier or Make

If you're not a coder, just look for platforms that mention "no-code" or that work with tools you already use.

How much do image generation APIs typically cost?

Prices vary quite a bit, but here's the general pattern:

• Free tiers usually give you between 50-200 images per month
• Starter plans cost around $20-50/month for a few thousand images
• Business plans range from $80-200/month for tens of thousands of images
• Enterprise plans have custom pricing for really high volumes

Most platforms charge based on how many images you generate, not on file size or complexity.

Are the images created with these APIs copyright-free?

Generally, you own the rights to images you create with these tools, but there are a few things to consider:

• If you use stock images or templates from the platform, check their terms
• AI-generated images might have specific usage terms
• Always read each platform's terms of service about intellectual property

What's the difference between a template-based API and an AI image generation API?

Template-based APIs (most platforms in this article):

• Use pre-designed templates that you customize
• Give predictable, brand-consistent results
• Work better for business uses where consistency matters

AI image generation APIs (like some features in DALL-E or Flux or Stable Diffusion):

• Create images from text descriptions
• Offer more creative and unique outputs
• Work better for creative projects where uniqueness is important

How do I choose the right image generation API?

Consider these factors:

• What types of images you need (static images, GIFs, videos, PDFs)
• How many images you'll generate each month
• What other systems you need to connect to
• Your budget
• Whether you need special features (face detection, video support, etc.)

The best approach is to start by testing the free tiers of 2-3 platforms that seem to match what you need.
