note: >-
  Close maintains two first-party API clients (Python and Node.js) and links a
  community list of wrappers from its API Clients page. Versions and publish
  dates below were read from the registry metadata endpoints on 2026-08-13.
  Both official SDKs are materially stale relative to the API: the Python client
  last published 2023-07-25 and the Node client 2019-11-11, while the API shipped
  Forms, Playbooks, Blocked Phone Numbers, Field Enrichment and an OpenAPI spec
  in 2025-2026. Close's own docs describe the API as "usable in any programming
  language" and point developers at community wrappers.

      Listed on Close's API Clients page. No Hex.pm package resolved for this

      there is no registry metadata endpoint to read a version from.
