Enhance a raw user prompt into a detailed, model-friendly prompt using the AI guide that matches the target model and inference type.

Set type (v2 dot notation) and model_slug to pick the right guide.
For images.edits and videos.animations, also send the source image (URL, data-URI, base64, or file).
Synchronous — the enhanced prompt is returned directly in the response body ({ prompt, negative_prompt }).

Required fields: prompt, type, model_slug (plus image for images.edits / videos.animations). The returned negative_prompt is provided for compatibility and is ignored by models that do not support negative prompts (e.g. FLUX.2 Klein).

Accepted `type` values

images.generations, images.edits, videos.generations, videos.animations, audio.speech, audio.music Only prompt-driven inference types have a booster. Upscaling, background removal, OCR, transcription and embeddings are not supported and are rejected with 422.

Example (image-to-image)

curl -X POST "https://api.deapi.ai/api/v2/prompts/enhancements" \
  -H "Authorization: Bearer <TOKEN>" \
  -F "prompt=Make it look like a digital photo" \
  -F "type=images.edits" \
  -F "model_slug=Flux_2_Klein_4B_BF16" \
  -F "image=@source.jpg"

Then send the returned prompt to the matching generation endpoint (e.g. POST /api/v2/images/edits).
