  Registry metadata endpoints (registry.npmjs.org, pypi.org, rubygems.org,
  repo.packagist.org, crates.io) plus the Sendspark docs
  (https://help.sendspark.com/api-reference) and the public GitHub organization
  (https://github.com/sendspark).
summary:
  official_count: 0
  third_party_count: 3
  note: >-
    Sendspark publishes NO first-party client library in any public registry.
    The documented integration path is direct HTTP against
    https://api-gw.sendspark.com with the x-api-key + x-api-secret headers, or
    the hosted read-only MCP server. The only public GitHub repository in the
    sendspark organization is `docs` (the Mintlify documentation source) — there
    is no SDK repository. Every package below is community/third-party and is
    recorded as evidence of the integration ecosystem, not as a Sendspark SDK.
