The endpoint returns a ready-to-use image URL and a task ID to track processing status. Ideal for apps needing automated image creation. **Prerequisite:** To ensure a successful request, you must first consult the [Model Selection](/api/v1/utilities/model-selection) endpoint to identify a valid model `slug`, check specific **limits** and **features**, and verify **LoRA** availability. Please **omit** the LoRA parameter by default during initial testing. ## OpenAPI ````yaml openapi.json POST /api/v1/client/txt2img openapi: 3.0.0 info: title: deAPI REST API description: >- Decentralized AI inference API for image generation, video processing, audio transcription, and more. contact: name: deAPI Support url: https://deapi.ai email: support@deapi.ai version: 0.0.1 servers: - url: https://api.deapi.ai description: Production API Server base URL security: - bearerAuth: [] tags: - name: Client API description: Endpoints for client operations paths: /api/v1/client/txt2img: post: tags: - Client API description: Endpoint for requesting text2img inference operationId: requestTxt2Image parameters: - $ref: '#/components/parameters/AcceptHeader' requestBody: description: Image generation parameters required: true content: application/json: schema: required: - prompt - model - width - height - guidance - steps - seed properties: prompt: description: The main prompt for image generation type: string example: A beautiful sunset over mountains negative_prompt: description: Elements to avoid in the generated image type: string example: blur, darkness, noise nullable: true model: description: >- The model to use for image generation.
