  Valimail publishes NO first-party client SDK for its hosted APIs
  (Configuration, Account Management, Partner, Reporting) — integration is raw
  REST with a bearer token obtained from POST /auth. The packages below are
  Valimail's first-party open-source email-authentication libraries published
  from the ValiMail GitHub org; they implement protocol primitives
  (SPF/DKIM/DMARC/ARC/DANE), not the Valimail API. Registry currency was read
  from each registry's metadata endpoint on 2026-08-14 and is a decay signal:
  every one of these libraries last shipped between 2017 and 2024, and the npm
  package has not published since 2018 — none of them tracks the APIs Valimail
  ships today.

    No package in the first-party set has shipped a release since June 2024,
    and the only JavaScript package has been dormant since November 2018. The
    Configuration API (v1.1.0) and Partner API this repo captures postdate every
    one of them, so no published library wraps the current API surface.
