# Wan Text-to-Image

## Overview

Create an asynchronous text-to-video task with a supported model. Use the returned task ID to retrieve its state, or provide callback_url for terminal delivery.

### Quick start

1. Create an API key and set it as RUNAPI_API_KEY.
2. Choose a supported model and send a POST request whose body matches that model's schema.
3. Store the returned task ID, then poll until a terminal state or handle the terminal callback.

## Endpoint

POST /api/v1/wan/text_to_image

Base URL: https://runapi.ai

API version: v1

Authentication: Authorization: Bearer YOUR_API_TOKEN

## Supported models

Open a model page for current pricing, rate limits, and commercial-usage details.

- [wan-2.7-image](/models/wan/2.7-image)
- [wan-2.7-image-pro](/models/wan/2.7-image-pro)

## Request schema

Fields and allowed values depend on the selected model. When supplied, callback_url receives a terminal task delivery.
