OASIS API Core

The core library of the OASIS API — the Open Advanced Secure Interoperable Scalable-System.

OASIS API Core contains all foundational interfaces, base classes, enums, data models and provider contracts that the entire OASIS ecosystem builds upon. Every OASIS provider, the ONODE WebAPI, and STAR ODK all depend on this library.

Part of the OASIS Omniverse

- OASIS Omniverse Reboot and Rebrand: major ecosystem relaunch under oasisomniverse.one after ~3 years of deep development.
- Added WEB6 (The AI Layer) with full LLM routing via FAHRN — supports OpenAI, Anthropic Claude, Cohere, HuggingFace, and Azure OpenAI.
- Added WEB7 (The Spatial/AR Layer), WEB8 (The Holographic Layer), WEB9 (The Neural Layer), and WEB10 (The Omniversal Layer) decentralised API tiers.
- Added ONET P2P network with FAHRN (Federated Adaptive Holonic Routing Network) and HolonicBraid mesh routing.
- Added OASIS HyperDrive v2 with DHT-based distributed storage and replication.
- Added OASIS MCP Server for seamless WEB4-WEB10 tool integration.
- Full implementation of all remaining provider interface stubs across all ~55 OASIS Providers.
- Security overhaul: CORS hardening (open/pluggable API policy), JWT validation fixes, NuGet vulnerability remediation across all projects.
- Fixed GetKarmaAsync returning 0: now falls back to AvatarDetail.Karma when in-memory cache is empty.
- Auto-creates AvatarDetail on first karma award if it does not exist yet.
- Fixed MongoDB holon save always inserting instead of updating for REST clients.
- Fixed circular reference serialisation causing truncated JSON in loadHolon responses.
- Fixed null max_tokens causing 400 errors across OpenAI, Cohere, AzureOpenAI, and HuggingFace providers.
