## API status — read this before trying to integrate

Acadia's own product factsheets state that Margin Manager is "accessed via Web user
interface, direct API or SFTP". That API is real, and it is entirely private:

- There is NO public OpenAPI, Swagger, GraphQL, AsyncAPI, gRPC or WSDL contract.
  Probed 2026-09-06 across acadia.inc, www.acadia.inc, portal.acadiasoft.com,
  cadence.acadia.inc and www.lseg.com.
- There is NO public developer portal, API reference, quickstart or sandbox.
- The product documentation portal is https://portal.acadiasoft.com/ — an Atlassian
  Confluence instance (realm "docportal") that 302s every anonymous request to an
  OAuth2 authorization endpoint. Access requires a customer account.
- There is NO MCP server, no A2A agent card, no llms.txt and no /.well-known document
  of any kind on any Acadia host.
- There is NO status page (status.acadia.inc and status.acadiasoft.com do not resolve)
  and no published pricing, rate limits, SLA or deprecation policy.

An agent cannot call Acadia. Integration begins with a commercial conversation:

## What Acadia does publish publicly

- simm-lib — https://github.com/AcadiaSoft/simm-lib
  MIT-licensed Java implementation of the ISDA SIMM initial margin model (v2.5 and all
  prior versions) plus the ISDA Schedule method. Consumes ISDA CRIF-formatted input and
  returns initial margin in USD. Passes ISDA's own one-day and ten-day benchmark suites.
  Not on Maven Central; built from source, or resolved via JitPack.
  Latest tag 2.5.0 (2022-09-19); last commit 2023-07-25.
  The README directs users to the Open Source Risk Engine
  (https://github.com/OpenSourceRisk/Engine) for all future SIMM versions.

## Standards Acadia speaks

- ISDA SIMM 2.5 — benchmark-verified in simm-lib
- ISDA CRIF (Common Risk Interchange Format) — the library's entire input surface
- ISDA Schedule (grid) initial margin method
