For developers & integrators
Building credential issuance into an existing product — APIs, webhooks, SDKs, Blockcerts interop.
You have an integration to ship, not an education platform to run. LearnCoin is REST-first, webhook-driven, and standards-conformant — the API surface is designed to fit into whatever backend you already have, and the credentials are readable by any Blockcerts or W3C VC tool your partners might use.
What you're up against
The pains this page exists to answer
- !Assistive UI you don't need — you're integrating, not issuing from a dashboard.
- !Proprietary credential formats that lock your users into a specific verifier.
- !Vendors whose API documentation lags six months behind their actual surface area.
- !Unclear migration path if the vendor's product direction changes.
Why LearnCoin fits
What specifically maps to this use case
REST + GraphQL, idempotent writes
POST /v1/batches with an Idempotency-Key header. Webhooks for batch.anchored.v1, credential.claimed.v1, credential.revoked.v1. Exponential backoff on delivery retry.
Standards-native output
Every signed credential is W3C VC 2.0 + Blockcerts v3 + Open Badges 3.0. The signed JSON-LD is the only integration contract — no proprietary wrapper format to reverse-engineer.
Test mode, free forever
lrn_test_ API keys anchor to Base Sepolia and are unlimited. Ship your integration without a credit card. Upgrade to live mode when you're ready to issue production credentials.
Open-source Blockcerts forks
Our Base L2 chain support is contributed upstream to lds-merkle-proof-2019 and explorer-lookup. The verification path is Blockcerts-canonical; no LearnCoin-specific verifier required.
Typical organisations
Backend engineers integrating credential flows into existing LMSes, SaaS products with a credentialing adjunct, internal platform teams at universities, Web3 / identity startups.
