# GENBN > Public registry for identifiers of books created with generative AI. Registration is open to publishing services. lazybook.ai is the first planned official publisher. ## Integration documentation - [Integration guide](https://genbn.org/integration.md): Registration, email confirmation, credentials, minting, URL updates, retries and recovery. - [OpenAPI](https://genbn.org/openapi.json): Public publisher API contract. Admin access is separate and not needed for integration. - [Category catalog](https://genbn.org/api/v1/categories): Canonical supported category/subcategory pairs. - [Register a service](https://genbn.org/register): Human registration and API key recovery. Use server-side credentials. Never include real API keys in prompts, generated frontend code, or public repositories. Registration verifies email ownership, not publisher identity.
