Bug (问题描述)

The Documentation section in langchain-paddleocr/README.md links to:

https://docs.langchain.com/oss/python/integrations/providers/baidu

But this URL returns 404 page. It also points to the general Baidu provider rather than documentation for langchain-paddleocr or PaddleOCRVLLoader.

There does not appear to be a currently published dedicated LangChain page for this integration. Because PaddleOCRVLLoader uses the PaddleOCR official Python API client, I suggest replacing the broken link with this link:

https://www.paddleocr.ai/latest/en/version3.x/inference_deployment/serving/paddleocr_official_api/python.html

Optionally, the README can also link to the PaddleOCR-VL deployment and inference tutorial page:

https://www.paddleocr.ai/latest/en/version3.x/pipeline_usage/PaddleOCR-VL.html

‍♂️ Environment (运行环境)

Documentation-only issue. Reproduced in a web browser on September 16, 2026.

Minimal Reproducible Example (最小可复现问题的Demo)

Follow the steps:

1. Open langchain-paddleocr/README.md
2. Scroll to the “Documentation” section.
3. Click “LangChain Docs.”
4. Observe the 404 response.

Expectation was a live documentation page relevant to PaddleOCRVLLoader.

Actual behavior: the linked LangChain Baidu provider page returns 404.
