By calling our API, you can quickly integrate the photo app into your application or service, enhancing User Experience and product value.

Our platform features include:

• Diversified image/video generation applications : Provide a variety of image generation applications to meet the needs of different scenarios.

• Easy integration : Integrate powerful image/video generation capabilities into your project with a simple API call.

• Efficient performance : Optimized algorithms and server architecture ensure fast response and high-quality image/video output.

• Flexible customization : supports multiple parameter settings to meet personalized image generation needs.

Whether you want to provide personalized image/video generation services for your users or need to automatically generate images in internal systems, our platform can provide powerful support for you.

API Charging Rules

The API interface will generate watermark-free images for you, so that you can use the images/videos in your personal business. There are two types of image generation applications on the a1.art site: node apps and form apps.

• Call the API of the APP to generate images. The form application consumes 1 credit for each generated image. The node-type application deducts credits according to the number of nodes. The fine-drawn image consumes 3 credits for each generated image. For details, please refer to: 节点式应用 VS 表单式应用 | Node Filters VS Form Filters

• Call the image-to-video API to generate videos, and 10 credits are consumed for each video generated.

You can subscribe to a1.art through a Visa card to obtain points, or contact us directly to discuss setting up a custom plan.

Please pay attention to keeping the account balance sufficient to avoid call failure affecting the normal use of your business

What capabilities does the API provide?

API currently provides 5 interfaces:

1. Get APP information: APP information can be browsed through the web application details page - API pop-up window, or obtained through the API interface to understand the basic information and imported parameters of the APP.

1. Upload image interface : if the user is using the image generation function, you need to call this interface to upload images before you can get the parameters of the image generation dependency

2. Image/Video Generation Interface: Users input the parameters on which the image/video generation depends, and can obtain a taskId. Through the taskId, the generated image/video results can be queried.

3. Fine drawing interface: high definition processing of the incoming image, similar to the raw image interface, after obtaining the taskId, the raw image result can be queried through the taskId

4. Query raw graph result interface: pass in the taskId can query the raw graph result

Basic introduction

Access authorization

Prefix

https://a1.art

Note: If you encounter problems with registration in China, you can try using the domain name https://a1art.xiaopiu.com

Request specification

• Network protocol: HTTPSprotocol.

• Encoding format: UTF-8encoding.

• Request header: You must carry apiKey for background authentication and authentication. (Get API key)
