## API

### Estimate the price

POST /v1/estimate takes a JSON body ({ model, input }) and returns the price for that input before you run it. This endpoint does not need an API key.

```bash
curl -X POST "https://api.sakuranbo.ai/v1/estimate" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "sakuranbo/cherryimage-1.0-pro",
  "input": {
    "prompt": "A matte ceramic coffee mug on a walnut desk, soft morning light, shallow depth of field",
    "resolution": "2k",
    "aspect_ratio": "4:3"
  }
}'
```

### Generate

Send generation requests to /v1/images/generations. The request below uses an example input from the catalog for this model.

```bash
curl -X POST "https://api.sakuranbo.ai/v1/images/generations" \
