description: >-
  Synthflow publishes no first-party server-side SDK in any language. The docs teach the
  Platform API with raw curl/requests examples in seven languages rather than a client
  library. The only first-party npm artifact is an n8n community node. A first-party
  Python CLI is claimed in Synthflow's own published Agent Skill, but no such package
  exists on PyPI under that name — see discrepancies below.

    note: >-
      n8n community node for Synthflow AI, scoped to the @synthflow-ai npm org and built
      from a repo in the SynthFlowAI GitHub org, so first-party. Its published
      description covers only the "Make a Call" endpoint, i.e. it wraps one operation
      (voice-call), not the API. Last release 2025-11-21 — roughly nine months before
      this probe, during which the Platform API grew to 100 operations and added phone
      books, memory stores, simulations and webhook logs.

    note: >-
      Distributed from GitHub, not a package registry, so there is no registry metadata
      endpoint to date. Version 1.0.0 is read from the plugin marketplace manifest
      (.claude-plugin/marketplace.json); no release tag or dated publication is exposed,
      so `published` is honestly null. Saved verbatim under skills/.

  first_party_count: 0
  note: >-
    No first-party client library on npm, PyPI, Maven Central, NuGet, pkg.go.dev,
    RubyGems, Packagist or crates.io. The Authentication and API Reference pages ship
    copy-paste snippets for curl, Python (requests), Go (net/http), Ruby (net/http),
    Java (Unirest), C# (RestSharp) and Swift (URLSession) — generated request samples,
    not a supported SDK. Integration is therefore raw HTTP, the n8n node, the MCP server,
    or the Agent Skills.

    impact: >-
      An agent following Synthflow's own published skill would install an unrelated
      third-party package from PyPI and then fail on every documented command. Because no
      first-party CLI could be verified in any registry or in the SynthFlowAI GitHub org,
      no cli/ artifact and no CLI pointer were emitted for this provider.
