📄 Description

Overview

Adds integration documentation for NewsCatcher CatchAll, a web search API that finds distributed real-world events across millions of sources and returns structured data. The integration includes both programmatic client access and agent toolkit for LangGraph workflows.

Type of change

Type: New documentation page

Related issues/PRs

  • GitHub issue: N/A (first-time contribution)
  • Feature PR: N/A (integration package already published to PyPI)

Checklist

  • I have read the contributing guidelines
  • I have tested my changes locally using make dev
  • All code examples have been tested and work correctly
  • I have used root relative paths for internal links
  • I have updated navigation in index files (tools/index.mdx and providers/all_providers.mdx)

Additional notes

Files Added/Modified

  1. Tool documentation (docs/src/oss/python/integrations/tools/newscatcher_catchall.mdx)

    • Complete setup and installation instructions
    • Three invocation patterns: direct, ToolCall, and within agent
    • Real-world examples tested with actual API
    • Agent-specific features and optimization patterns

  2. Provider documentation (docs/src/oss/python/integrations/providers/newscatcher.mdx)

    • CatchAllClient for programmatic access
    • Async support for concurrent operations
    • Cost optimization patterns
    • Links to tool documentation

  3. Tools index (docs/src/oss/python/integrations/tools/index.mdx)

    • Added card in alphabetical order (between Naver and Nuclia)
    • Added table row with pricing and return data info

  4. Providers index (docs/src/oss/python/integrations/providers/all_providers.mdx)

    • Added card in alphabetical order (between Naver and Neo4j)

Package Information

Testing Details

  • Local build completed successfully (make build)
  • Dev server verified all pages render correctly (make dev)
  • Navigation tested: cards and table entries appear in correct alphabetical positions
  • All internal links verified (no 404s)
  • All external links tested and functional
  • Code examples tested with live API (examples use real query results)

Note on Deprecation

Examples use langgraph.prebuilt.create_react_agent which shows a deprecation warning in LangGraph v1.0+. This is intentional, as the new langchain.agents.create_agent has not been tested with this integration yet.
