  Registry metadata read unauthenticated from registry.npmjs.org, pypi.org/pypi/<pkg>/json,
  rubygems.org/api/v1/gems/<pkg>.json and proxy.golang.org, plus the first-party GitHub
  organization https://github.com/SynapseFI (HTTP 200, 11 public repositories).
note: >-
  Synapse Financial Technologies is defunct — it filed Chapter 11 on 2024-04-22 and the case was
  later dismissed/converted after the asset sale to TabaPay collapsed and no qualified bids were
  received. Every synapsefi.com host (synapsefi.com, api.synapsefi.com, docs.synapsefi.com,
  help.synapsefi.com) now fails DNS resolution (NXDOMAIN, probed 2026-08-29), so the API these
  packages wrap is no longer reachable. The packages themselves remain published on their public
  registries and are recorded here as the surviving first-party evidence of the API surface.
  ABANDONMENT SIGNAL: the newest first-party release in any registry is 2023-06-28 (npm
  synapsenode 2.0.0-beta.11) — more than three years old, and still a pre-release beta.
ownership_check: >-
  All npm packages below are published by Synapse-owned maintainer accounts
  (pchen_synapsefi, synapse_frontend, sean_synapsefi, japamat_synapse, nicklassynapse,
  tynasynapse, synapsepay); the PyPI, RubyGems and Go modules resolve to the
  github.com/SynapseFI and github.com/synapsepay organizations (SynapsePay was the company's
  earlier brand). No third-party fork is marked official.

    note: >-

    note: >-
      Only ever released as 1.0.0. The SynapseFI/SynapseFI-Ruby repository was last pushed
      2022-07-21, three and a half years after the single gem release.

  - name: github.com/SynapseFI/SynapseGo
    registry: go
    url: https://pkg.go.dev/github.com/SynapseFI/SynapseGo
    language: Go
    official: true
    version: v0.0.0-20230109194625-d93ca2a00ca1
    published: '2023-01-09'
    repository: https://github.com/SynapseFI/SynapseGo
    description: Go wrapper for the Synapse REST API.
    note: >-
      Pseudo-version only — the module was never tagged with a semantic version, so consumers
      pin a commit hash rather than a release.

  - name: SynapsePHP
    registry: github
    url: https://github.com/SynapseFI/SynapsePHP
    language: PHP
    official: true
    version: null
    published: null
    repository: https://github.com/SynapseFI/SynapsePHP
    description: PHP client library for the Synapse REST API.
    note: >-
      Checked Packagist for synapsefi/synapse-php and synapsefi/synapsephp — both 404. The PHP
      client is distributed only as a git repository with no tagged releases, so there is no
      registry metadata to read and no version a consumer can pin. Repository last pushed
      2026-04-18.

  - name: SynapseFI-PHP

    version: null
    published: null
    repository: https://github.com/SynapseFI/SynapseFI-PHP
    description: Earlier SynapseFI PHP API wrapper.
    note: Not on Packagist (404). Repository last pushed 2019-08-09.

  - name: SynapseRuby
    registry: github
    url: https://github.com/SynapseFI/SynapseRuby
    language: Ruby
    official: true
    version: null
    published: null
    repository: https://github.com/SynapseFI/SynapseRuby
    description: Second-generation Synapse Ruby client.
    note: >-
      No gem of this name is published on RubyGems (synapse-ruby and synapsefi both 404), so it
      is source-only with no pinnable version. Repository last pushed 2023-04-13.

components:
  note: >-
      Synapse also published its front-end component libraries to npm under the same
      Synapse-owned maintainer accounts. These are UI packages, not API clients, and are listed
      here for completeness rather than as SDKs.
