      points at https://api.crawl4ai.com.

  - name: crawl4ai-cloud-sdk
    registry: source
    official: true
    language: python
    url: https://github.com/unclecode/crawl4ai-cloud-sdk/tree/main/python
    repository: https://github.com/unclecode/crawl4ai-cloud-sdk
    license: Apache-2.0
    version: 1.2.0
    published: null
    note: >-
      SOURCE-ONLY. Version read from python/pyproject.toml; there is no PyPI
      release — pypi.org/pypi/crawl4ai-cloud/json, crawl4ai_cloud and c4ai-cloud
      all return 404 (probed 2026-08-29), so `published` is honestly null. The
      Python Cloud SDK is also two minor versions behind its own Node.js (1.4.0)
      and Go (v1.4.0) siblings in the same repository.

      https://github.com/unclecode/crawl4ai-cloud-sdk/tree/main/python/claude-plugin
    repository: https://github.com/unclecode/crawl4ai-cloud-sdk
    license: Apache-2.0
    version: 1.0.0
    published: null
    note: >-
      Distributed through the repo's own .claude-plugin/marketplace.json rather
      than a package registry, so there is no registry date to read. Ships four
      Agent Skills and a local stdio MCP server — captured in skills/ and mcp/.
third_party_note: >-
  npm carries a large third-party Crawl4AI ecosystem (crawl4ai 1.1.0 by pyronaur,
  mcp-crawl4ai-ts, @gkzhb/crawl4ai-mcp, n8n-nodes-crawl4ai*, pi-crawl4ai). None of
  these are published by unclecode or CONTEXT4AI PTE LTD and none are recorded
  here as official.
