x-no-public-api: true
x-no-public-api-reason: SEI Investments does not publish a public developer portal, OpenAPI specifications, SDKs, sandbox
environments, or self-serve API keys. The SEI Wealth Platform, SEI Data Cloud, SEI Sphere, SEI Novus, and SEI Access for
CITs are delivered to institutional clients (banks, RIAs, asset managers, pension plans) under contract, with integrations
arranged through SEI onboarding, professional services, and partner programs. There is no developer.seic.com, api.seic.com,
or public GitHub organization for SEI as of this profiling. The "SEI Connect" naming sometimes referenced in advisor partner
contexts is not a public API product with documentation or specifications available outside contractual relationships.
