📄 Description

Overview

Surface the Perplexity Search API integration in LangChain's Python docs by documenting PerplexitySearchRetriever and PerplexitySearchResults (both already exist in langchain-perplexity) alongside the existing ChatPerplexity page.

  • Updates src/oss/python/integrations/providers/perplexity.mdx to add Retriever and Tools sections plus a components reference table.
  • Adds src/oss/python/integrations/tools/perplexity_search.mdx (mirrors the structure of tools/exa_search.mdx): standalone tool.invoke("query") example, advanced filter walkthrough, and a create_react_agent example.
  • Adds src/oss/python/integrations/retrievers/perplexity_search.mdx (mirrors the structure of retrievers/tavily.mdx): instantiation, filtered usage, and a simple RAG chain.
  • Adds discovery entries in tools/index.mdx (Search table) and retrievers/index.mdx (External index table + All retrievers card grid).

All constructor and call-time arguments are taken directly from langchain_perplexity.tools.PerplexitySearchResults and langchain_perplexity.retrievers.PerplexitySearchRetriever — no invented APIs.

Checklist

  • I have read the contributing guidelines, including the language policy
  • I have tested my changes locally using docs dev
  • All code examples have been tested and work correctly
  • I have used root relative paths for internal links
  • I have updated navigation in src/docs.json if needed

(Internal team members only / optional): Create a preview deployment as necessary using the Create Preview Branch workflow

Additional notes

  • The src/docs.json integrations tab only enumerates per-component index pages and a curated "Popular Providers" list — it does not list every individual provider/tool/retriever page, so no docs.json change is needed for these new pages to appear at their canonical paths.
  • Pages link to the canonical Perplexity Search API docs (quickstart, API reference, domain filter, date/time filter) and to the Perplexity API key dashboard.
  • make check-cross-refs (the repo's cross-reference validator) and the unit test suite both pass on this branch.
