description: 'MultiLynq is a fixed income trading technology company founded in 2018
  by Patrick Scheideler and Scott Collins and based in Shrewsbury, New Jersey. It sells
  market integration as a service: a single high-performance API that normalizes the
  messaging and trading protocols of every major and emerging electronic U.S. fixed
  income trading venue — including MarketAxess, Tradeweb, Trumid, Bloomberg, ICE Bonds,
  LTX by Broadridge, Liquidnet, Octaura, TMC Bonds and Bonds.com — into one interface
  for credit, municipal bond and loan trading. The platform covers pre- and post-trade
  workflows including price dissemination, market data aggregation, RFQ negotiation,
  portfolio trading, auction mechanisms, quoting conventions, smart order routing,
  and post-trade reporting and reconciliation, delivered as a fully hosted solution
  in which clients establish a single physical connection to a MultiLynq data center
  while MultiLynq maintains all upstream venue connectivity. The company has raised
  funding from Citadel Securities and Jane Street. The API is the entire product, but
  it is sold and onboarded through a sales conversation: MultiLynq publishes no public
  developer portal, documentation, specification, SDK or pricing.'

  description: 'MultiLynq''s single normalized API for electronic fixed income trading
    across every major and emerging U.S. venue. It abstracts each venue''s native
    messaging and trading protocol — RFQ negotiation, portfolio trading, auctions and
    quoting conventions — behind one interface, and carries pre- and post-trade
    workflows including price dissemination, market data aggregation, smart order
    routing, and post-trade reporting and reconciliation. No baseURL is recorded because
    MultiLynq publishes none: the service is fully hosted and reached over a dedicated
    physical connection into a MultiLynq data center that is provisioned per client
    during onboarding, and no public endpoint, specification or documentation exists.'

  detail: >-
    MultiLynq's API is its entire product, but the company publishes only a
    four-page WordPress brochure site whose single call to action is a contact
    form stating "a member of our team will be in touch shortly" — there is no
    docs, api or developer subdomain in DNS at all, so the specification exists
    solely inside a per-client onboarding engagement.
