Practical overview
When it fits
Use it when a Python application needs Sider.ai chat or image OCR through a Session-based client, and you can provide the required Sider authentication token.
Who it is for
- Python developers building applications that send prompts through Sider.ai.
- Developers who need OCR text from image files through the same client.
Documented uses
- Send a prompt to a selected model and collect its progressively streamed response.
- Extract text from an image file using the OCR method.
- Continue or begin conversations using a server-side context ID.
Requirements & limits
- The documented installation is through pip, and examples use the
sider_ai_apiPython import. - Chat and OCR both return string generators that yield responses progressively.
- An empty context ID starts a new conversation; the README describes conversation context as server-side.
- The README identifies the project as MIT-licensed.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install the library and prepare a Session
Set up the documented Python client for Sider.ai chat and OCR.
Before you start
- Python environment with pip
- Sider authentication token
- Cookie information for OCR image uploads
Steps
Install the package with the command below.
pip install sider-ai-apiImport
Sessionfromsider_ai_api.Create a Session with the Sider token and, for OCR, the fuller cookie string.
Expected outcome
A configured Session object ready for the documented chat or OCR methods.
Guide limitations
- A token is required for Session authentication.
- The README says token-only access can work for chat, but OCR image uploads may require additional cookie values and can encounter a Cloudflare verification error.
