MultiLynq

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.

MultiLynq publishes 1 API on the APIs.io network. Tagged areas include Company, Fixed Income, Bond Trading, Capital Markets, and Financial-Services.

MultiLynq’s developer surface includes support and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/multilynq: open an issue to ask a question, or submit a pull request to add artifacts.

  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.
