Acadia

Acadia, founded in 2009 as AcadiaSoft, provides risk, margin and collateral management services to the global uncleared OTC derivatives market and now operates as part of LSEG Post Trade following LSEG's December 2022 acquisition. Its AcadiaPlus platform — Agreement Manager, Margin Manager, Collateral Manager, IM Exposure Manager, Payments Manager, Settlement Manager and Relay, alongside the Risk Suite analytics services — connects more than 2,000 market participants for initial-margin calculation, margin-call messaging, reconciliation, dispute resolution and settlement. Acadia's own factsheets state its applications are reachable by web user interface, direct API and SFTP, but that interface is delivered under customer contract: the product documentation portal is authenticated and no public specification is published. The company's one public machine-readable artifact is simm-lib, an MIT-licensed Java implementation of the ISDA SIMM initial-margin model.

Acadia is profiled on the APIs.io network. Tagged areas include Company, Financial Services, Capital Markets, Derivatives, and Risk Management.

Acadia’s developer surface includes changelog and 11 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/acadiasoft: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Acadia's entire product documentation set lives on an Atlassian Confluence instance at portal.acadiasoft.com whose
    every anonymous request 302s to an OAuth2 authorization endpoint with realm=docportal, and whose own OpenID/RFC 8414 discovery
    documents return 401 — so the direct API its factsheets advertise has no publicly readable contract, reference or limits.
