summary: >-
  APILayer ships Node.js only, and says so: "Right now, we only have the Node.js SDK. If you are
  a developer and love to write code, join us to build SDKs in different languages and
  environments." Five per-product client packages plus one React chart component, all published
  by the npm user `api-layer` and all linked from apilayer.com/developers/suite/, which is what
  makes them first-party. Nothing exists on PyPI, Maven Central, NuGet, pkg.go.dev, RubyGems,
  Packagist or crates.io - the packages named `apilayer` on npm and `ApiLayer` on PyPI are
  third-party and unrelated.

  Every first-party package was last published between October and December 2024 - roughly two
  years stale as of this check - while the product contracts kept moving (Marketstack and
  Serpstack are both on 2.0.0). No package declares a repository or homepage in its registry
  metadata, so there is no public source tree to read, and none of the five carries a source
  link on GitHub even though APILayer maintains an active org there. Nothing covers the three
  APIs captured in this repo: there is no client for exchangerate.host, exchangeratesapi.io or
  ipapi.com.

  products_with_sdk: 5

  note: 17 of APILayer's 22 published contracts have no first-party client library in any
    language.
