Listia is a peer-to-peer marketplace where members give away and acquire secondhand goods using an internal virtual currency ("Points") rather than cash. Launched in 2009 and backed by Andreessen Horowitz, the service lets members list unwanted items in auction-style listings, earn Points when an item sells, and spend those Points to claim items from other members — a closed-loop credit-and-reputation economy layered on a classic online-auction flow. The site reports over 10 million members, operates iOS and Android apps alongside the web marketplace, and runs adjacent programs including Listia Rewards (redeeming Points for gift cards and retail goods) and Listia Assurance (buyer and seller protection). Listia publishes no public developer program: there is no developer portal, no API documentation, no OpenAPI or other machine-readable specification, and no first-party SDKs on npm, PyPI, RubyGems or Packagist. The api.listia.com host serves the same Rails application as the website and acts as the private backend for the mobile apps, not a documented public API.
