-H "Content-Type: application/json" \
-H "X-API-Key: $EACHLABS_API_KEY" \
-d '{
"model": "aifaceswap-face-swap",
"version": "0.0.1",

curl -X POST https://api.eachlabs.ai/v1/prediction \
-H "Content-Type: application/json" \
-H "X-API-Key: $EACHLABS_API_KEY" \
-d '{
"model": "faceswap-video",
"version": "0.0.1",
"input": {
"target_video": "https://example.com/target-video.mp4",
"swap_image": "https://example.com/source-face.jpg"
}
}'
```
### Alternative: Using GPT Image v1.5 Edit
For prompt-based face replacement:
```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
-H "Content-Type: application/json" \
-H "X-API-Key: $EACHLABS_API_KEY" \
-d '{
"model": "gpt-image-v1-5-edit",
"version": "0.0.1",
"input": {
"prompt": "Replace the face in image 1 with the face from image 2. Keep the same pose, lighting, and expression. Maintain natural skin tone and seamless blending.",
"image_urls": [
"https://example.com/target-photo.jpg",
"https://example.com/source-face.jpg"
],
"quality": "high"
}
}'
```
## Prediction Flow
1. **Check model** `GET https://api.eachlabs.ai/v1/model?slug=<slug>` — validates the model exists and returns the `request_schema` with exact input parameters. Always do this before creating a prediction to ensure correct inputs.
2. **POST** `https://api.eachlabs.ai/v1/prediction` with model slug, version `"0.0.1"`, and input matching the schema
3. **Poll** `GET https://api.eachlabs.ai/v1/prediction/{id}` until status is `"success"` or `"failed"`
4. **Extract** the output image URL from the response
## Tips for Best Results
- Use high-quality source images with clear, well-lit faces
- The source face image should be a clear frontal or near-frontal portrait
- Matching lighting conditions between source and target produces more natural results
- Specify "seamless blending" and "natural skin tone" in prompts
- For the target image, faces should be clearly visible and not heavily occluded
