If you’ve been burned by “free” image generation APIs that ask for your card after signup, you’re not alone. At Kousouf Agency, we did the dirty work — tested everything, ran real curl requests, and weeded out the fakes. Here’s a no-fluff breakdown of what works, what doesn’t, and how you can start generating images right now — 100% free.
✅ The Only 3 Truly Free Text-to-Image APIs (We Tested Them)
1. Cloudflare Workers AI – Most Powerful Free Tier
- 10,000 free neurons/day (~10–20 full-res images).
- Based on Stability AI (SDXL).
- Fast, high quality, no watermark.
Example curl:
curl --location 'https://api.cloudflare.com/client/v4/accounts/YOUR_ACCOUNT_ID/ai/run/@cf/stabilityai/stable-diffusion-xl-base-1.0' \
--header 'Authorization: Bearer YOUR_TOKEN' \
--header 'Content-Type: application/json' \
--data '{"prompt":"cyberpunk cat"}'
2. Modelslab – Easy, Fast, But Limited Use
- 20 image credits total (not per day).
- Sign up for API key, no credit card.
- Watermarked output, but perfect for testing.
Example curl:
curl -X POST https://modelslab.com/api/v6/images/text2img \
-H "Content-Type: application/json" \
-d '{
"key":"YOUR_API_KEY",
"model_id":"stabilityai/stable-diffusion-2-1",
"prompt":"a neon cyberpunk street at night",
"width":512, "height":512
}'

3. AI Horde (Stable Horde) – Fully Anonymous, No Signup
- 100% free and community-powered.
- No API key needed (use
apikey: 0000000000). - Slow queue-based generation, but solid output.
Step 1 – Submit job:
curl -X POST -H "apikey: 0000000000" -H "Content-Type: application/json" \
-d '{"prompt":"a futuristic city skyline","params":{}}' \

Step 2 – Check status:
curl -H "apikey: 0000000000" \

❌ These Ones Didn’t Deliver
| API | Why It Fails |
|---|---|
| DeepAI | Says free, but blocks with credit card wall |
| getimg.ai | Claims “40 images free” — instantly blocked by quota error |
| Clipdrop | Website bug prevents claiming credits |
