  npm registry (registry.npmjs.org search + package metadata), Packagist
  (packagist.org/packages/list.json?vendor=antavo + repo.packagist.org/p2),
  github.com/antavo, and https://developers.antavo.com/docs/api-signing
note: >-
  Antavo publishes no self-service SDK page; the client libraries below were
  found by searching the public registries for the `antavo` vendor/scope plus
  the Escher signing libraries the API signing documentation links to by name.
  Every first-party package carries a version and a published date read from
  the registry metadata endpoint. THE CURRENCY FINDING IS THE HEADLINE: the
  newest first-party Antavo release on any registry is @antavo/microsite-sdk-node
  3.9.5-DEV from 2021-10-06, and the newest non-prerelease is
  @antavo/api-async-client-node 1.0.1 from 2021-06-08 - roughly five years
  behind the REST API these libraries wrap, whose reference pages were last
  updated in 2026. Antavo's own developer documentation does not link to any of
  them; it points integrators at the Postman collection and at generic Escher
  implementations instead.

    Linked by name from https://developers.antavo.com/docs/api-signing as the
    reference implementation for signing Antavo requests. The GitHub repository
    was last pushed 2026-04-09 but no release has been tagged to Packagist
    since 1.2.1 (2018-12-13), so `composer require` still installs the 2018 build.

- language: java
  registry: null

  url: https://github.com/emartech/escher-java
  official: false
  version: null
  published: null
  note: >-
    Linked from https://developers.antavo.com/docs/api-signing as a supported
    Escher implementation. Published by Emarsys (emartech), not Antavo; no
    registry coordinates are given in Antavo's documentation, so no version was
    read.

  registry: null
  name: escher-csharp
  url: https://github.com/emartech/escher-csharp
  official: false
  version: null
  published: null
  note: >-
    Linked from the Antavo API signing document. A fork also exists at
    github.com/antavo/escher-csharp (last pushed 2018-10-25). Not published to
    NuGet under an Antavo identity, so no registry version is recorded.
- language: go

  url: https://github.com/EscherAuth/escher
  official: false
  version: null
  published: null
  note: >-
    Linked from the Antavo API signing document. Community Escher implementation;
    Antavo publishes no Go module of its own, so no proxy.golang.org version was read.
