Solar Mosaic

aid: solar-mosaic
name: Solar Mosaic
description: Solar Mosaic, Inc. (trading as Mosaic) was a residential clean-energy lender founded in Oakland, California in
  2010, originally as a solar crowdfunding platform and from 2014 as a point-of-sale financing platform for residential solar,
  battery storage and other sustainable home improvements funded through third-party capital partners. Mosaic originated loans
  through a dealer/installer channel and backed more than $15 billion in home energy loans across roughly 360,000 households.
  Its integration surface for installer and capital partners was the Mosaic Financing API, documented on a password-protected
  ReadMe developer portal at developer.joinmosaic.com. Solar Mosaic filed for Chapter 11 bankruptcy in the Southern District
  of Texas on 2025-06-09 and its loan portfolio was acquired in September 2025 by Solar Servicing LLC, which stated it would
  not originate new solar loans. As of this profile the joinmosaic.com website 301-redirects to solarservicingllc.com, the
  api.joinmosaic.com host returns HTTP 503, and the Mosaic status page reports "Page Inactive".

  description: The Mosaic Financing API is the integration surface Solar Mosaic published for its solar installer, dealer
    and capital partners, documented on a ReadMe-hosted developer portal titled "Mosaic Financing API". The portal is password-protected
    — every path under developer.joinmosaic.com (including /reference, /docs and /openapi.json) 302s to /password and returns
    the ReadMe gate shell — so no public reference, operation list or machine-readable contract could be read. The baseURL
    below is the company-controlled API host that resolves and answers (nginx HTTP 503); it is NOT confirmed by documentation,
    because the reference that would confirm it is behind the password gate.

  detail: Solar Mosaic filed Chapter 11 on 2025-06-09 and its portfolio was acquired by Solar Servicing LLC, which does not
    originate new loans — joinmosaic.com now 301-redirects to solarservicingllc.com, the api.joinmosaic.com host answers nginx
    503 on every path, and the Mosaic status page returns 200 with the title "Mosaic Status - Page Inactive"; the only surviving
    API surface is a ReadMe portal titled "Mosaic Financing API" whose every path 302s to a password gate.
