# Generate Structured Prompt - Tailored Model

`POST /structured_prompt/generate/tailored`

**Description**

Creates a new detailed, machine-readable structured prompt in JSON format or refines an existing one using text inputs and a tailored model's visual schema (backbone).

This endpoint uses the state-of-the-art **Gemini 2.5 Flash** VLM bridge. The tailored model's visual schema is provided as input to Gemini along with the user prompt to generate the structured prompt.

**It returns ONLY the JSON string and does not generate an image.**

**Use Cases:**
* **Control & Auditability:** Inspect or programmatically edit the JSON *before* generating an image.
* **Consistency:** Generate one `structured_prompt` and pass it to `/image/generate/tailored` multiple times.
* **Hybrid Deployment:** Use Bria's VLM bridge via API while hosting the FIBO image model on a private cloud.

**Input Combination Rules**
The request body must use exactly one of the following combinations:
* **Text Only**: `prompt`
* **Structured Prompt and Text**: `structured_prompt` and `prompt` (Refinement)
