Okay, you’re looking for free API services for acquiring/generating images, right?

I’ve compiled a list of services that cover both generation (AI drawing) and acquisition (image library). These are all public APIs with free credits, and you don’t need to build your own inference service.

## **1. AI Image Generation APIs**
These are AI services similar to Stable Diffusion and DALL·E that can generate images from text.

### 1. **Hugging Face Inference API**
– **Address**: [https://huggingface.co/models](https://huggingface.co/models)
– **Fees**: Minute usage limit applies, but public models are free to use (queueing available)
– **Recommended Free Models**:
– `stabilityai/stable-diffusion-2-1` (high quality, medium speed)
– `runwayml/stable-diffusion-v1-5` (classic and stable)
– `prompthero/openjourney` (artistic style)
– `segmind/SSD-1B` (fast)
– **Call**:
“`
POST https://api-inference.huggingface.co/models/{model_id}
Header: Authorization: Bearer {HF_TOKEN}
Body: {“inputs”: “your prompt”}
“`

### 2. **OpenAI Images API (DALL·E)
– **Address**: [https://platform.openai.com/docs/guides/images](https://platform.openai.com/docs/guides/images)
– **Features**: Supports 1024×1024 generation, with a delicate illustration style

– **Features**: Provides various model interfaces (cartoon, ultra-high-definition, avatar, etc.)
– **Call**:
“`python
import requests
r = requests.post(

“https://api.deepai.org/api/text2img”,
data={“text”: “beautiful landscape, oil painting”},
headers={“api-key”: “YOUR_API_KEY”}
)
print(r.json())
“`

My suggestions:
– **If you want raw images/text**: Try Hugging Face first (free but potentially slow). For faster results, try the Pollinations API.
– **If you want stock images**: Use Pixabay (higher quota, more types), and use Unsplash as a backup for HD photography.

If you’d like, I can write a Python “automatic image retrieval function” for you. It allows you to choose between generation mode (AI drawing) or search mode (image library API), and then directly returns an image URL that can be posted to WordPress, allowing you to automatically add images to your posts.
Do you want me to write this for you?
