  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".

    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.

    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.
