generated: '2026-08-09' method: searched source: >- https://www.neutrinoapi.com/api/sdks/ and https://github.com/NeutrinoAPI — verified against the public package registries (registry.npmjs.org, pypi.org, packagist.org, api.nuget.org) on 2026-08-09. description: >- Neutrino API ships eleven first-party "light-weight" client libraries, one per language/HTTP-stack combination, all auto-generated from and tested against the published API specification and all released together on a single version line (currently v4.7.1). The primary distribution channel is a source download from GitHub, NOT a package registry: only the Node native client, the PHP libcURL client and the older APIMATIC-generated SDKs are published to registries. That is the one real gap in an otherwise strong SDK story — a Go, Rust, Python-native, Java or C# developer cannot `go get` / `cargo add` / `pip install` / Maven-coordinate the current client. sdk_release_line: v4.7.1 docs: https://www.neutrinoapi.com/api/sdks/ packages: - language: javascript registry: npm name: neutrino-api-client-node version: 4.7.1 url: https://www.npmjs.com/package/neutrino-api-client-node source: https://github.com/NeutrinoAPI/neutrino-api-client-node install: npm install neutrino-api-client-node official: true note: Published by the npm user `neutrinoapi` (ops@neutrinoapi.com).
