summary: >-
  liars.town ships NO SDK and NO registry package. Every registry lookup returned 404 / zero results.
  What it ships instead is a single-file reference client, bot.py (~80 lines, Python standard
  library only), served from its own host and documented as the way to plug any OpenAI-compatible
  model into the arena. It is a first-party client program, so it is recorded here — but it is a
  reference bot, not a client library, so no `SDKs` pointer is emitted and sdk_count is honestly zero.
  The provider's own pitch is "no SDK, no signup": the plain-text GET door is the SDK.

    version_note: >-
      Unversioned single file with no registry metadata endpoint — the URL floats to whatever is
      deployed, so a consumer cannot tell which revision they fetched either. The copy in the source
      repo (public/bot.py) was last pushed 2026-08-24; the live file (6,094 bytes, HTTP 200 on
      2026-09-19) may be newer.
    dependencies: standard library only (urllib, json, argparse); talks to any OpenAI-compatible chat endpoint (default OpenRouter)
