Provision DISHA 4.0 HCOS Sandbox Credentials & API Access
Accelerate your integration with test-environment API keys. Build, test, and validate decentralized identity verification, CEL ledger queries, and zero-knowledge underwriting flows with zero rate-limit restrictions during staging.
Sandbox Capabilities & Developer Environment Features
Everything you need to build, test, and validate your DISHA HCOS integration before going live.
Isolated Staging Network
Test endpoints without affecting live production identity ledgers or state registry records. Full environment parity with zero cross-contamination risk.
Pre-Populated Mock Persona Suite
Access test identities across student profiles, institutional issuing bodies, and verified skill achievements — ready for immediate sandbox queries.
Automated Key Rotation & Rate Limits
Manage environment secret keys, configure webhook endpoints, and inspect request payload logs in real time with zero manual overhead.
HCOS Stage 1–5 Sandbox Coverage
Multi-stage technical simulation environment available in the sandbox for comprehensive integration testing.
Decentralized Identity Testing
Mock decentralized identifier (DID) generation and cryptographic signature testing. Simulate sovereign identity anchoring for learners and institutions.
- ✓Mock DID Generation & Resolution
- ✓Cryptographic Signature Validation
- ✓Identity Schema Testing Suite
Credit Completion Simulation
Simulated credit completion blocks and certificate validity checks. Test immutable ledger writes and Merkle-tree anchoring without touching production data.
- ✓Simulated Completion Block Writes
- ✓Certificate Validity Check APIs
- ✓Merkle Proof Verification Testing
Zero-Knowledge Proof Testing
Zero-knowledge proof generation testing with pre-configured validation parameters. Validate ZK-SNARK circuits and proof assertions in a safe sandbox environment.
- ✓ZK-SNARK Circuit Simulation
- ✓Pre-Configured Proof Parameters
- ✓Privacy-Preserving Assertion Testing
Interactive Key Provisioning & Quickstart Console

Developer & Integration Team Testimonials
Engineering managers, solutions architects, and integration leads on zero-friction API key onboarding.
“We had our first API call returning mock ZK credentials within 20 minutes of receiving the sandbox key. The onboarding experience is genuinely frictionless.”
Rohan Kapoor
Senior Engineering Manager · EduTech Ventures
“The pre-populated mock persona suite saved us weeks of test data setup. We could simulate end-to-end skill loan underwriting flows on day one.”
Ananya Krishnan
Solutions Architect · FinSkill Labs
“Sandbox key provisioning was instant for our verified business domain. The staging environment is a perfect production mirror — no surprises during go-live.”
Vikram Nair
Integration Lead · GovTech Solutions
“The real-time request log inspector in the sandbox console is exceptional. We could debug ZK proof generation issues without any back-and-forth with support.”
Meera Joshi
Senior Engineering Manager · LMS Connect
“10,000 free staging API calls per month is more than enough to build a complete integration prototype. The rate limit generosity signals a developer-first culture.”
Siddharth Rao
Solutions Architect · CredVerify Systems
“The mock DID registry and pre-configured ZK parameters meant our team could test Stage 5 ZKPG flows without needing to understand the cryptographic internals.”
