Plug-and-Play Open APIs & Interoperable HCOS Credential Infrastructure
Seamlessly connect your learning platform to DISHA 4.0 HCOS with developer-first SDKs, real-time xAPI/LTI webhooks, and Zero-Knowledge credential issuance nodes.
Why EdTech Providers Choose DISHA HCOS
Overcome integration barriers and unlock universal credential interoperability.
Isolated Walled-Garden LMS Platforms
Proprietary LMS ecosystems lock learner data in silos, preventing cross-platform skill recognition and portability.
Interoperable Unified HCOS Ecosystem
Open xAPI/LTI-compliant data streams connect your platform to the HCOS ecosystem, enabling universal skill recognition.
Custom Proprietary Certificate PDF Exports
PDF certificates are easily forged, unverifiable at scale, and incompatible with employer verification workflows.
Universally Verifiable ZK-Skill Credentials
Cryptographically signed Zero-Knowledge credentials issued directly to learner wallets — tamper-proof and instantly verifiable.
Complex Manual Integration Pipelines
Weeks of custom engineering work to connect LMS platforms to external credential or analytics systems.
RESTful Open APIs & TypeScript SDK Client Packages
Full integration in under 2 days using our OpenAPI 3.0 spec, TypeScript SDK, and pre-built webhook connectors.
HCOS Runtime Stage Integration
Three core HCOS pipeline stages power the EdTech Provider integration layer.
Cryptographic Event Ledger
Automated event logging via lightweight xAPI/LTI streams into the immutable ledger. Every course completion, assessment pass, and skill milestone is cryptographically anchored — creating an auditable, tamper-proof learning record.
- ✓xAPI 2.0 & LTI 1.3 Compliant Streams
- ✓Immutable Merkle-Tree Event Anchoring
- ✓Real-Time Webhook Delivery (< 200ms)
Open Developer Platform
OpenAPI 3.0 specification, webhooks, and OAuth2 machine-to-machine authentication. Full developer tooling including TypeScript SDK, Python client, Postman workspace, and sandbox environment.
- ✓OpenAPI 3.0 Full Specification
- ✓OAuth2 M2M & API Key Auth
- ✓Multi-Language SDK Packages
Zero-Knowledge Proof Gateway
Issue tamper-proof micro-credentials directly into learner wallets without storing raw PII on partner servers. Your platform triggers credential issuance; HCOS handles the cryptographic proof generation.
- ✓ZK-SNARK Credential Issuance Engine
- ✓PII-Free Partner Server Architecture
- ✓Learner Wallet Direct Delivery
