Developer platform / SDK programme

LargeQuant in the stack you already use.

REST and OpenAPI are the canonical production contract today. Tier-1 SDK source is already maintained for eight ecosystems; registry publication and automated contract-parity release engineering are completed in LQDX4.

Tier-1 source

Eight official SDK codebases already follow the LargeQuant contract.

“Maintained source” means SDK code is present in the LargeQuant distribution. It does not imply that a package is already published to a public registry.

Common abstraction

The SDKs wrap the same Omni and platform contracts.

Language packages should remain idiomatic while preserving the same identity, request ID, idempotency, run lifecycle, evidence and error semantics as REST.

Developer access

Start with REST. Move to official packages when LQDX4 publishes them.

The API contract does not change when you move from direct HTTP calls into a native SDK.
