Wrap LargeQuant Omni into your own product.
LargeQuant exposes one stable Omni contract across Finance, Risk, Treasury, Physics, Molecular, Biology and Scientific Discovery, backed by test/live identities, deterministic sandbox execution, request IDs, rate limits, evidence and developer observability.

}LQDX3 developer workflow
From key to observable integration.
The Developer Console now brings credentials, a no-secret-storage API playground, request logs, webhook deliveries, usage and integration documentation together in one place.
Create
Discover Omni
Call /api/v1/omni and inspect capability contracts for each quantitative world.
Run safely
Use deterministic sandbox mode before moving the same contract to lq_live_.
Observe
Trace request IDs, latency, status, rate-limit state and signed webhook delivery from the console.
Authentication
Personal keys for development. Service accounts for machines.
Authorization: Bearer is the canonical transport. LargeQuant also supports X-LargeQuant-API-Key as a hosting-safe fallback. Service accounts bind production access to organization, workspace, project and environment boundaries.

Official SDKs
Eight Tier-1 source contracts are already in the platform.
Node/TypeScript, Python, PHP, Laravel, CodeIgniter, Java, .NET and Dart/Flutter SDK source exists today. Registry publication, contract-generation checks and automated package release are the dedicated LQDX4 step; REST remains the production contract until that seal is complete.

Commercial model
Evaluate in sandbox. Scale into governed production.
Developer evaluation uses deterministic test mode. Production access uses live credentials, commercial entitlements, Quant Balance telemetry and institutional controls where required.
